Dear Friends

Th e recently held Singapore International Water Week (SIWW) 2010 and World Cities

Summit 2010 brought the world’s major stakeholders on a common platform to fi nd

solutions to the most important challenges confronting every country in the world.

SIWW also served as a showcase to highlight Singapore’s capabilities and achievements

in attaining water sustainability and in addressing the issues of urban transformation.

While much of the attention was focused, and correctly so, on the challenges at the

national-, state- and city- level during the SIWW, it must be pointed out that there are

a lot of possibilities at the facility-level engineering and management to conserve energy

and water resources. Experts have stated that energy-saving, particularly in buildings,

can have a greater impact on the issue of sustainability, than the harnessing of renewable

energy sources. Likewise, the use of recycled water such as NEWater and ‘grey water’

for non-potable applications, within the premises of buildings, can help to achieve the

desired degree of conservation of water as well as energy.

Th e project teams responsible for the creation of buildings should therefore give the

utmost importance to these objectives at the earliest stage of the design process. Further,

facility engineers and managers have the task of ensuring energy-effi cient and water-

effi cient operation of buildings.

I am heartened to note that relevant technical committees within IES are playing their

part in highlighting the importance of facility design, operation, and management,

and enhancing the standing of the professionals working in these fi elds; organising

professional training; and managing certifi cation programmes. In this way, we can

ensure that buildings are designed and operated in a sustainable manner.

Come 4 September 2010, IES will be launching the National Engineers’ Day (NED) at

*SCAPE, with Deputy Prime Minister and Minister for Defence Mr Teo Chee Hean as

Guest-of Honour. Intended to promote the engineering profession as an attractive career

among the young, especially at the secondary school levels, NED promises to be an

extravaganza of engineering-centric activities and exhibits which will appeal to the target

audience. Among the programmes will be the hosting of secondary school students by

engineering fi rms. We hope to count on your support to make NED a success!

IES Update

Singapore Aerospace Forum 2010On 25 June 2010, the IES Aerospace Engineering Interest Group, Singapore Institute of Aerospace Engineers, and Singapore Polytechnic, organised the Singapore Aerospace Forum 2010 that addressed the subject ‘Seletar Aerospace Park (SAP)’. It was attended by about 130 participants.

Prof Yeoh Lean Weng, IES Vice President and Chairman for IES Industrial Group, in his welcome address, said, ‘The aviation industry in Singapore is a thriving one, having been identified as a key component of Singapore’s quest to become a major transport hub. Singapore has evolved to become a major aerospace maintenance, repair and overhaul (MRO) centre in the Asia Pacific region. Our sustained high growth has created strong clusters of aerospace activity, mainly concentrated in the Changi area’.

‘With Asia expected to double its fleet of aircraft by 2018, we can be certain that the Singapore aerospace industry will experience exponential growth. No longer will Changi alone be sufficient to serve the needs of the rapidly expanding industry. This is why the Seletar Airport has been identified as a dedicated aerospace facility to meet the needs of the industry’, he added.

Four speakers, namely Mr Kevin Chow, Deputy Director, Precision Engineering and Transport Engineering, Singapore Economic Development Board, Ms Tang Wai Yee, Director, Aerospace, Marine & CleanTech Cluster, JTC Corporation, Mr Koh Chwee, Director, Engineering Planning Division, JTC Corporation, and Mr Daniel Ng, Deputy Division Head, Aviation Industry Division, Civil Aviation Authority of Singapore (CAAS), gave their presentations on the latest developments and projects that their respective organisations are embarking on.

After the presentations, Prof Yeoh presented plaques to the speakers as tokens of appreciation.

Cover Story: Dawson Estate BTO Projects

SkyTerrace @ DawsonWinner of a Green Mark for Buildings

Award, for Residential New Buildings,

under the Platinum category, at

BCA AWARDS 2010, the Housing &

Development Board (HDB) Build-To-

Order (BTO) project also received the

ABC Waters Certifi cation from PUB,

the national water agency.

DESCRIPTION OF PROJECT

‘Housing in a Park’

Located in Dawson Estate, the project site is bounded on the north and east by Margaret Drive, and on the west by Dawson Road. Running along its entire southern boundary is the Alexandra Canal Linear Park. Th e key driving concept of the project is the creation of ‘Housing in a Park’ and a ‘City in a Garden’, with the public residential development set in a scenic park-like environment.

In response to this vision, the intention is to convert Margaret Drive into an ecological corridor with fi nger park linkage to the Alexandra Canal Linear Park along the eastern boundary of the site. Th e project site will thus eventually enjoy seamless connectivity to greenery on three sides. Th is green concept is further brought into the development by introducing lush landscaping on the ground plane, which travels up the building facades taking the form of green terracing, roof gardens, and green sky terraces.

Multi-generational living and

community building

Th e project design aims to reinforce the idea of multi-generational living and community building by providing extended families the opportunity to buy interconnected loft units. Th ese loft units are designed such that a paired larger fl at and a studio apartment can be combined by removal of the internal walls.

Th e concept of community building is further promoted by creating a variety of active and passive recreational spaces to allow for greater communal interaction. Th ese community spaces and integrated recreational facilities are designed in a park-like setting, enabling residents to enjoy the natural environment.

THE PRECINCT DESIGN

Th e 758-unit development comprises fi ve residential 40-storey to 43-storey towers and a 4-storey linear multi storey car park (MSCP) podium.

Th e MSCP podium is connected to the residential towers by bridges, at every level of the podium, enabling the residents to have an uninterrupted covered entry experience from the car parks to the lift lobbies and to their apartments.

Running east-west along the central spine of the project, and interspersed by pockets of greenery, is the Heritage Gallery, the main circulation spine, which celebrates the history of Dawson Estate, whilst spatially linking the residential towers and MSCP with various community and recreational facilities – outdoor amphitheatre, precinct pavilion, community centre, children’s playground, fi tness corner etc. All these amenities are located within easy walking distance from

all the blocks.Th e site planning takes full advantage

of the long north and south boundary, by aligning the residential towers along this axis, thereby maximising the development’s north-south exposure. A formal main entrance and drop-off court is carved out in the north-west corner which connects to a peripheral road that runs along the western, south-western, and northern boundary, and loops into the MSCP. Th is road also serves as the service access route to the residential towers. Th e majority of the southern periphery of the development is thus preserved as a vehicle-free green park that opens up seamlessly to the Alexandra Canal Linear Park.

LANDSCAPE STRATEGY

Th e landscaping concept aims to provide

the residents with a natural and green living environment and complements the idea of community living by creating a varied collection of communal spaces within the development.

Th e main arrival into the development is at a shaded arrival court anchored by two large rain trees and a formal canopied drop-off area. Th is space is linked to the residents’ lift lobbies and other communal facilities through the Heritage Gallery. Th e residents enter their homes at the end of a journey that is complemented by landscaped courts and green vistas. Th e soft landscaping strategy here is to provide trees that introduce vertical rhythmic elements and shade to the journey, and ground cover that imparts colour and texture to the garden spaces.

Th e southern periphery of the Heritage Gallery extends out to a

generous open lawn that stretches out and seamlessly merges with the Alexandra Canal Linear Park. On the eastern edge of this lawn space sits an outdoor amphitheatre that serves as a focal point for the community.

Adjacent to the amphitheatre are located the active recreation facilities like the children’s playground, fi tness corner, and outdoor badminton courts.

Th e northern periphery of the site is currently lined with existing mature rain trees. Th e landscape design responds to this environment by the addition of similar rain trees to complement the scale and rhythm of the existing foliage, and the planting of low level shrubbery to create lushness at pedestrian scale. Th ere is careful and sensitive selection of shrubbery and ground cover to subtly announce the three pedestrian entrances

to the development that run south towards each of the residential towers facing the ecological corridor. Th is area will blend seamlessly with the ecological corridor in the future, especially with the introduction of a linear bio-retention basin along the northern periphery.

Th e green concept is reinforced by having cascading green terraces and edge planters that screen the bulk of the MSCP, culminating in a green landscaped roof of the MSCP. Ascending from the adjacent open lawn at ground level, landscaped terraces on the southern side of the MSCP provide a continuous route with intermediate communal spaces, up to the green roof above. Th ese terraces, together with the green roof, serve as convenient communal gathering spaces for the residents due to their close proximity to the residential towers. Th e majority of the green roof is covered by a linear undulating turfed area, anchored by a tai-chi court, on one end, and a multi-purpose trellis covered court, on the other. Low-level shrubbery and small trees are planted along the sides of the roof to defi ne the edges and provide shade and screening to the residents.

Adjacent residential towers are linked by sky terraces at two levels. Th us there are sky terraces at levels 13 and 28, 18 and 33, and 19 and 34, connecting pairs of adjacent towers. Th ese serve as fi re refuge holding areas as well as communal gathering points that provide unparalleled views of the surrounding cityscape. Each

BLOCK & UNIT LAYOUT

Block layout

Each residential block is designed with four units on each fl oor, which are served by three lifts and two staircases.

Th e common areas are designed to have through-ventilation, including the staircases which are clad with lightweight metal mesh. In the evenings, back-lighting to the staircases converts the mesh cladding into a silhouette, creating a ‘lantern eff ect’.

Th e service areas of the units are grouped close to the core of the block, making available the outer periphery



Th e sky terraces serve as communal gathering points that provide unparalleled views of the surrounding cityscape.

for major spaces like living rooms and bedrooms.

As each fl oor has only four units, only one unit occupies each of the four wings of the block, ensuring privacy and minimising the amount of common areas in this compact layout.

Unit layout

Th e apartment design is based on one of two confi gurations - the multi-generational loft unit and the double-height loft unit.

Multi-generational loft units are a combination of a double-storey 4- or 5- room unit and a studio apartment. Th e double-storey unit enjoys a double-height living room that is attached to a loft space above. Th e buyer is provided the opportunity of purchasing and combining these apartments by connecting the upper storey loft space of the 4- or 5- room unit directly to an adjacent studio apartment. Each unit will still have its respective individual entrances, for privacy.

Th e double-height loft units are special apartments that enjoy a double-height living/dining room space. Th e ceiling height for this space is a soaring 5.4 m. Each double-height loft unit is designed to have a balcony as an extension of the living room space.

Generally, unit plans are designed with minimal structural beams traversing major spaces. Th is feature allows for fl exibility in catering for future conversion into diff erent bedroom confi gurations to suit the evolving requirements and lifestyles of residents. All living rooms and bedrooms have full perimeter frontage for best possible views out and maximum daylight penetration. Th is feature is enhanced by having full height windows for all the bedrooms and living rooms.

A service yard is provided for each unit for the washing and drying of clothes. Th ese yards and other service areas of the units like bathrooms face the internal elevations of the block, keeping the main external facades clean and uncluttered.

ELEVATION DESIGN

Th e tower elevation design showcases the interlocking spaces that are created by the loft concepts. Units are clearly defi ned by architectural edge fi ns that give a clear

crisp silhouette to the tower facades as well as provide some sun-shading to the south-facing facades. Spanning vertically between the fi ns are full-height windows. Th ese, together with the vertical groove lines on the pre-cast panels, provide an interesting relief pattern on the facades, which creates an additional level of detail and refi nement to the elevations.

As an extension of the site landscaping, the MSCP elevations are softened with green terracing and edge planting. Th is green elevation concept is carried through vertically to the sky terraces that span horizontally between the tower blocks at staggered intervals, thus providing compositional juxtaposition to the verticality of the towers.



GREEN FEATURES

Th e design of the project incorporates a green strategy which has several components. Th e green features are expected to produce energy savings of 793,962 kWh/yr and water savings of 40,616 m3/yr.

North-south orientation

Th e fi ve residential tower blocks are oriented north-south, to minimise solar gain to the apartments.

Th e facades of the towers consist predominantly of pre-cast panels and full-height windows. East and west facing facades are designed to have minimal openings and all windows are installed with low-e glass to further minimise heat gain. Th e Residential Envelope Transmittance Value (RETV) achieved is 18.01W/m2.

Th rough-ventilation of common areas

Typical lift lobbies and common areas are designed to maximise through-ventilation. Staircases are clad with lightweight metal mesh which introduces a large degree of porosity and openness to the staircase enclosures. Together with the open parapets surrounding the typical lift lobbies, uninterrupted fl ow of air across the common spaces is encouraged.

Bio-retention basins

Bio-retention basins are incorporated on the northern, western, and south-western peripheries of the site, to catch storm-water surface run-off from the peripheral road. Th e water that percolates through these bio-retention basins undergoes a natural bio-fi ltration process that removes water borne pollutants and is stored in several underground catchment tanks. Th e stored water is then recycled for irrigating ground level landscaping. Excess water from the bio-retention basins is discharged directly into government drains in line with PUB’s ABC water policies.

Rainwater harvesting and drip

irrigation

In addition to bio-retention basins, a rainwater harvesting strategy is employed to irrigate above-ground landscaped areas at the sky terraces, the landscaped MSCP roof, MSCP green terraces, and edge

planters. Rainwater is collected from roofs and is fed to intermediate holding tanks by gravity, to irrigate these areas through a drip irrigation system.

Early estimates indicate potential water savings of about 40%. Th e system also allows for a top-up with PUB water to supplement the system during periods of low rainfall.

Water-effi cient fi xtures

Th is residential development has water-effi cient fi xtures such as water closets, bath mixers, wash basin mixers, and bib

taps, as certifi ed by the Water Effi ciency Labelling Scheme (WELS).

Solar panels

Solar panels are installed on the upper roofs of the towers, to harvest solar energy which will be used to supplement the power for common area lighting and lift operation in the residential towers. Preliminary estimates indicate potential minimum savings of 24.6% of the total power consumed using T5 fl uorescent fi ttings (the HDB requirement of 3.15 hours/day is used as the baseline).

BCA AWARDS 2010, the Housing &

Development Board (HDB) Build-To-

Order (BTO) project also received the

ABC Waters Certifi cation from PUB,

the national water agency.

INTRODUCTION

Th e project presents an opportunity for the team of design consultants to conceive and design a new and exciting vision for the future of public housing in Singapore.

Th e design proposal re-thinks conventional norms for public housing by creating spaces that range in scale, location, and function.

Th e Sky Villages, Rooftop Penthouse, • Urban Plaza, and social facilities, help foster community spirit.

Confi gurable unit layouts allow • expression of individuality and diversity of character.

A sustainable environment is achieved • by utilising good passive design, a variety of foliage, and on-site renewable energy, creating the potential to reduce energy consumption and carbon emissions.

Th e design for Skyville @ Dawson is the product of integration of the three key concepts of community, variety, and sustainability, as mutually benefi cial concepts, and presents a glimpse of what the future of public housing in Singapore could be.

Skyville @ Dawson will be a precedent for HDB’s new generation of public housing.

Located in Queenstown, the site for Skyville @ Dawson is bounded on the north and east by a newly aligned Margaret Drive and Dawson Road. Th e south boundary runs parallel to the Alexandra Canal Linear Park. Th ere are many mature trees in this estate which will be conserved and developed into a landscaped park, covering about 30% of the site area.

Th e 960-unit public housing development is located within the HDB landscaped master plan for the Eco Corridor and Alexandra Canal Linear

Park. Th is project will be developed by HDB to fulfi l the vision of creating ‘Housing in a Park’, where public housing is set in a scenic park-like environment.

COMMUNITY

Th is project aims to build communities. A rich variety of sheltered and outdoor community spaces are designed to encourage social interaction among residents at diff erent scales and levels. By strategically locating these spaces along the daily routes of residents, this becomes part of their daily life.

Interaction takes place when residents cross paths at the ground level lift lobby of their blocks. Here they collect their mail, wait for the lifts, wait for school buses, or they can sit in the community living room to enjoy a chat as well as the serenity of the landscaped park just next to it.

Th e landscaped park and the landscaped deck of the podium block provide interaction spaces in an outdoor setting. Th ese accommodate precinct pavilions, playgrounds, fi tness stations, and beautifully landscaped gardens, for the enjoyment of residents, their families, and their communities.

FLEXIBILITY IN LAYOUT

All the apartment units are designed with beam-free ceiling in core spaces, and with columns along the perimeter, to maximise fl exibility in unit layout. Residents will enjoy a range of unit layouts with a variety of options in terms of living room and master bedroom sizes, and number of bedrooms, to suit their individual lifestyles and family needs.

THE FAÇADE

Th e tower façade is designed to highlight the diff erent clusters, with the sky gardens providing visual relief at regular intervals, as well as punctuating the solid element with a dispersion of voids and landscaping.

Each cluster within the block is characterised by a colour that diff erentiates it from other clusters, to

give a sense of identity.Th e playful staggering of the vertical

wall fi nishes and colours lends a rich and varied touch to the tall stately towers, thereby providing a special character to this development.

THE LANDSCAPE

A rich variety of landscaped areas is designed to bring an enjoyment of nature into the high-rise living environment.

Both the residential towers and the multi storey car park will be landscaped at the roof levels as well as at the sky villages.

At ground level, there is a huge landscaped park with majestic rain trees on the north side, 13 of which have been earmarked for conservation. Th e bio-swale, integrated at the edge of the towers, creates an eco-feature water garden, while at the same time pre-treating hardscape water run-off and managing storm-water.

Skyville @ Dawson has an intensive green roof system at the tower blocks, multi storey car park, and the adjoining 3-storey building. Th e extent of coverage

Th e tall, stately towers are conspicuous even when viewed from a distance. Th e landscaped areas bring enjoyment of nature into the high-rise living environment.

Th e buildings are topped by an intensive green roof system and there are sky gardens at various levels of the tower blocks.



of the green roofs is about 4,690 m2, out of the entire building roof top area of about 9,370 m2.

Sky gardens are created on the 3rd, 14th, 25th, and 36th storeys of the tower blocks. Each of these sky gardens is a communal sky village of 80 units. Residents share these community spaces just outside their doorsteps.

Residential units are also in close proximity to the Alexandra Canal Linear Park which forms part of the nation-wide park connector network.

SUSTAINABILITY

A sustainable environment is achieved in this project through utilising good passive design and a variety of foliage, and installing solar panels, thereby creating the potential to reduce energy consumption and carbon emissions.

Building orientation

Th e buildings are 100% north-south facing and more than 70% of the dwelling units enjoy true cross ventilation.

Computer simulation

In order to design and identify eff ective layouts and dimensions of the buildings, which will ensure cross ventilation, Computation Fluid Dynamics (CFD) simulation of natural ventilation within the units, was carried out at the design stage.

Daylighting and thermal analyses were also carried out during the initial design stage to identify the optimum façade design that would achieve a balance between reducing solar heat gain, allowing daylighting to permeate, and ensuring cost-eff ectiveness. A Residential Envelope

A grid-tied mono-crystalline PV system is incorporated into the roof garden features, to supplement the energy requirement for the common area lighting.

Transmittance Value (RETV) of 19.56 W/m2 was obtained.

Renewable energy

A grid-tied, mono-crystalline, photovoltaic (PV) system is incorporated into the

roof garden features to supplement the energy requirement for the lighting of the common areas. Th e capacity of the PV modules installed is 125kWp and the estimated electrical output is approximately 137 MWh/year.



Lighting

Th rough good daylighting designs and the use of energy-effi cient T5 light fi ttings with high frequency ballasts for the illumination of all common areas, the buildings aim to achieve savings in the power consumption for lighting, of more than 55%, as compared to a typical code-compliant building. In addition, motion sensors are installed to control the lights at the half landings of each staircase, so that half of the lights will be automatically switched off when there is no movement of people along the staircases, further reducing the energy consumption of the lighting.

Th rough the incorporation of PV technology and an effi cient lighting system, an estimated overall energy savings of approximately 394 MWh/year could be achieved for Skyville @ Dawson.

Dwelling units

Th e message of sustainability and ‘green living’ is extended into the dwelling units as well. All the water fi ttings such as basin taps, and WC fl ushing cisterns used, are rated ‘Very Good’ (2 Ticks) under the Water Effi ciency Labelling

Scheme (WELS). Th e estimated overall water savings for Skyville @ Dawson is approximately 53,000 m3/yr.

Eff orts were also taken during the design phase to ensure a good indoor environment quality within the residential units. All wet areas will be adequately ventilated with good daylighting and all refuse chutes will be located in open areas in the common corridors.

Environment-friendly materials

Where possible, the construction materials used will be certifi ed by Singapore Green Labelling Scheme (SGLS).

Non-structural elements will be made with concrete incorporating ground granulated blastfurnace slag (GGBS), and environment-friendly water-proofi ng materials will be used in all the wet areas.

Environmental protection

A compost bin centre will be installed at the ground level to promote recycling of landscape clippings as well as organic wastes, which will be used for landscaping. At the ground level, recycling bins for paper, plastics, and metals, will be located at the lift lobbies for use by the residents.

Dual bins will also be provided at the common refuse chutes on every level, to promote the concept of recycling among the residents.

Bicycle parking lots will be allocated at each tower block to encourage alternative transportation. In addition, the development is located within walking distance to the bus stop and the MRT station, further reducing the carbon emissions from transportation.

CONCLUSION

Skyville @ Dawson is among the forerunners that defi ne the new generation of public housing in Singapore. Th is BTO project sees the implementation of sustainable technologies at a large enough scale to show meaningful results on environmental sustainability design and also to deliver long-term savings to the end-user.


Interview

Energy-effi cient performance guaranteed

Artist’s impression of Gardens by the Bay.

‘Th e Singapore Engineer’ speaks to Mr

Pay Ngiap Poh, Vice-President – Asia

Energy Solutions, Ingersoll Rand,

Climate Solutions Asia Pacifi c, and asks

him about the company’s capabilities

and contributions in the area of energy

management in buildings.

Question: Trane has all along been a

well-known name in airconditioning

equipment and systems. When did

the company move into the role of an

ESCO (Energy Services Company)?

Answer: About 15 years ago, Trane started

providing Energy Services and Asset

Management Services in the US, and we

have been moving well. In Asia, we were

not doing much in this area. Around

three years ago, we decided to focus on

Asia by launching a bridgehead – Trane

Asia Energy Solutions – in Singapore,

and that is when we started off ering these

services.Mr Pay Ngiap Poh.


Interview

Q: How are the prospects for ESCOs in

Singapore and Asia, in both newbuilding

and refurbishment projects?

In general, the business opportunities have

gone up tremendously. With the emphasis

on ‘green’ buildings, there is a real need

to reduce the energy consumption of

buildings, with the airconditioning alone

accounting for up to 60% of the total.

With respect to the retrofi tting of

existing buildings in Asia, the prospects

are good as there are a lot of ‘matured’

buildings, especially in cities like Bangkok,

Hong Kong, Kuala Lumpur, Singapore,

and Taipei.

As a result of the need for energy

services, our Asia Energy Solutions expects

to grow 30% year-on-year.

Q: What are your comments on the

incentives being given to building

owners to incorporate ‘green’ features

in their projects?

A: With the widespread awareness of

global warming and climate change, we

see several countries in the region, such

as Japan, Th ailand, China and Korea,

introducing energy-saving programmes

that include incentives. Singapore has also

taken action, and the incentives provided

are good.

But for energy-savings to be actually

realised, accurate measurement of the

performance of the systems, particularly

the airconditioning system, is important.

Q: What are some of the projects that

Trane has successfully undertaken?

A: At our bridgehead in Singapore, we

have laid the foundation, and built up

the team through transfer of knowledge

and training. We have already established

a track record here, with completed and

ongoing projects such as Singapore Post

Centre, Th e Galen, Mapletree Business

City, and New Tech Park. Trane also

supplied our energy-effi cient chillers to

the national project - the Gardens by the

Bay.

We have several jobs in Malaysia

including Penang Times Square,

Dammansara Oasis, Parkson Shopping

Complex in Kuala Lumpur, and Hotel

Parkroyal Kuala Lumpur.

In Th ailand, we secured the Seagate

and Tetrapak building projects. We are

also moving to North Asia. A notable

project here is the Hong Kong Jockey

Club.

Q: What are the highlights of Trane’s

contributions in Gardens by the Bay?

A: Th e Conservatory Complex in Gardens

by the Bay comprises a ‘Cool Dry biome’

and ‘Cool Moist biome’, for the plants

and fl owers of two diff erent geographical

environments.

We supplied airconditioning

equipment including energy-effi cient

chillers, as well as the controls for the two

biomes.

Th e Gardens by the Bay project will

use Trane's Building Automation System

(BAS), which facilitates web-based facility

management of multiple buildings.

Th e BAS will control the functioning

of the diff erent equipment and systems in

the two biomes, including those for solar

tracking, fogging, shading, irrigation,

ACMV (Air Conditioning Mechanical

Ventilation), and lighting.

Q: What guarantees do you give on the

performance of chiller plants?

A: Trane gives 3-year, 5-year, and 10-

year guarantees on the performance of

chiller plants which are maintained by the

company.

For example, in Mapletree Business

City, we have a performance guarantee

of 0.65 kW/ton energy effi ciency, for a

cooling load varying from 2,000 ton to

10,000 ton.

Q: What is the signifi cance of the

acquisition of Trane by Ingersoll Rand?

A: Ingersoll Rand’s diversifi cation started

10 years ago. But it was in 2007 that

the company sold its road construction

machinery, construction equipment, as

well its utility equipment and attachment

products businesses. In December of the

same year, Ingersoll rand acquired Trane.

Th is gives the company a strong focus

in the area of ‘Climate Solutions’, together

with Th ermo King and Hussmann.

Whilst Trane is a leader in

airconditioning systems, services, and

solutions, Th ermo King manufactures

temperature control systems for a variety

of transportation modes including trailers,

trucks, buses, shipboard containers, and

railway cars.

Hussmann provides display cases,

refrigeration systems, installation, and

services to food retailers around the

world.

Trane’s Building Automation System will control the functioning of the diff erent equipment and systems in the two biomes at Gardens by the Bay.


Sustainable Energy Application

Solar Assisted Heat Pump – research and

development at NUSEnergy is considered to be a prime

agent in the generation of wealth

and a signifi cant factor in economic

development. Of all known energy

sources, solar energy is considered

clean and inexhaustible.

Solar energy is particularly suitable

for low temperature applications and

off ers an excellent opportunity for its

use with heat pumps. Th e unglazed

evaporator-collectors absorb both

solar energy and ambient energy due

to the low operating temperature.

At the National University of

Singapore (NUS), three diff erent

systems have been designed, fabricated

and installed. Th ey are:

A solar assisted heat pump system •

for producing hot water using an

unglazed evaporator collector.

A solar assisted heat pump for hot •

water production, drying, and space

cooling.

A solar assisted heat pump system •

for desalination using an unglazed

evaporator-collector and a solar liquid

collector.

Dr M N A Hawlader, Mr Zakaria

Mohd Amin, and Dr Ye Shaochun,

Department of Mechanical

Engineering, NUS, describe the three

systems.

INTRODUCTION

Taking into consideration the growing

energy needs and concerns regarding

environmental degradation, greater

attention is being given to clean and

inexhaustible energy sources, such as

solar energy, for various applications.

Th e use of solar energy systems

reduces pollution and waste, and has

little or no harmful eff ects on the

environment. It is understood that this

source of energy can complement, rather

than compete with, conventional energy

sources.

A combination of solar energy and

heat pump can improve the quality of the

energy available and has the potential for

being utilised in diff erent applications

[1- 2]. Th e evaporator-collector used in

such a system can absorb both solar and

ambient energy [3-4]. Huang and Lee

[5] studied the long-term performance

of solar assisted heat pump water heaters.

Grossman [6] conducted experiments

with a solar heat pump system to

provide cooling, dehumidifi cation, and

airconditioning. In 2003, Hawlader et al

[7, 8] conducted a series of experiments

on the application of a Solar Assisted

Heat Pump (SAHP) system for water

heating, drying, and desalination.

APPLICATION OF SAHP SYSTEMS

At NUS, several SAHP systems were built

for the evaluation of their performance in

various thermal applications, under the

meteorological conditions of Singapore.

SAHP for water heating

Th e most common use of solar thermal

energy is in the area of water heating.

Heat pumps are becoming more

popular, since they are more energy-

effi cient and have a better performance

than conventional heating systems such

as those using gas or electricity.

Hawlader et al [9] developed a

SAHP water heater, as shown in Figs

1 and 2, and conducted experiments

on such a system operating under the

meteorological conditions of Singapore.

Th e system includes two serpentine,

unglazed, evaporator-collectors

connected in series. Th e ambient air also

acts as a heat source depending on the

operating temperature of the evaporator-

collectors.

Fig 1: Schematic diagram of a SAHP water heating system [9]. Fig 2: Photograph of a SAHP water heating system [9].



Fig 3: Schematic diagram of an integrated solar heat-pump system.

Integrated SAHP system

At NUS, an integrated system for

airconditioning, water heating, and

drying, was designed and built, as shown

in Figs 3 and 4. Th e various components

of the system are an evaporator-collector,

evaporator, variable speed reciprocating

compressor, air-cooled and water-cooled

condensers, drying chamber, blower, and

other control devices. Th e evaporator-

collector and evaporator are connected

in parallel with individual expansion

valves. Th e air-cooled and water-cooled

condensers are connected in series.

SAHP for desalination

Desalination processes involve phase

changes and require signifi cant energy

inputs. At NUS, a direct expansion SAHP

system for desalination was designed and

built [9].

In the desalination system, as shown

in Figs 5 and 6, the heat pump provides

heating and cooling for the desalination

process. In the desalination section, the

water is preheated using a liquid solar

collector.

Previously, only an electrical heater

was used to maintain the temperature of

the feed water at 70° C [10]. Currently,

the heater serves as a booster. Th e heat

exchange between water and refrigerant

occurs in the desalination chamber and

water condenser tank.

RESULTS AND DISCUSSION

SAHP water heating

Fig 7 shows the thermal performance of

the system in water heating with solar

radiation for diff erent collector areas.

Fig 4: Photograph of an integrated solar heat-pump system.

As seen from the fi gure, for a particular

collector area, if solar irradiation increases,

the Coeffi cient of Performance (COP),

the ratio of heat gain to compressor work,

increases. It may happen if the fl uid

temperature in the collector increases due

to high solar irradiation and reduces the

work of the compressor. Again, for the

same reason, for a particular size of the

compressor and specifi c solar irradiation,

the COP of the system increases with

increasing collector area.

Integrated SAHP system

Here, all the three applications (water

heating, drying, and airconditioning), are

implemented simultaneously. A room is

cooled down by this system. A cooling

load analysis has been done and this

system has a cooling capacity of at least

4200 W. Cooling capacity is a measure of

the total amount of cooling needed for an

enclosed area during a specifi ed period of

time.

A total of 10 towels are placed in a

drying chamber and dried by the hot air

from the air condenser. Th e weight of the

10 towels in the drying process is shown

in Fig 8. Th e temperature of the air inlet is

around 55° C while the temperature after

drying is around 30° C. It can be seen

initially that the temperature diff erence

between the inlet and outlet is larger and

gets smaller after the towels are dried.

Within 30 minutes, 1400 g of water

evaporate, leading to the drying of the

towels. Th ere is a drop in the temperature

of air at the outlet as the heat from the

air inlet is used to dry the towels. While

most systems vent out the warm air, this

system eff ectively makes use of it to dry

the towels.



SAHP for desalination

Desalination is performed and compared

at two compressor speeds (30 Hz and 35

Hz) under the meteorological conditions

of Singapore. From Fig 9, it can be seen

that at 35 Hz, more water is produced.

Th is is because at higher compressor

speeds, the refrigerant is driven at a

higher fl ow rate, resulting in more water

evaporation and condensation.

Performance Ratio (PR) is defi ned

as the amount of distillate produced per

2326 kJ of heat input. Th e value ‘2326

kJ’ represents the theoretical amount

of energy required for evaporating 1 kg

of water. Higher PR indicates higher

distillate production per unit heat input

and better utilisation of the thermal

energy of the system.

From Fig 10, it can be seen that

the PR is lower when the compressor

is running at 35 Hz. Under similar

solar irradiation conditions, distillate

production by the system is slightly

higher when the compressor is running

at 35 Hz.

CONCLUSION

Th e SAHP system is an eff ective and

environment-friendly solution for low

temperature applications.

Th is system uses both solar and

ambient energy, enabling operation even

at night. Th e effi ciency of the unglazed

evaporator-collector was found to be

much higher than that of the air or

liquid collector.

Th e application of SAHP principles

facilitates the development of an

integrated multi-task SAHP system,

where solar and ambient energy, and

waste heat from airconditioning, can

be used for water heating, drying,

desalination, and space cooling.

New Intelligent Power Manager software simplifi es supervision of UPSs and ePDUs

Th e Intelligent Power Manager software facilitates the cost-eff ective supervision of networked UPS systems and associated equipment.

Diversifi ed industrial manufacturer

Eaton Corporation recently announced

the introduction of an intuitive, cost-

eff ective, and secure software that

will enable Information Technology

(IT) managers and administrators to

remotely manage and monitor all of their

networked power and environmental

devices across the enterprise. According

to the company, its Intelligent Power

Manager software is a robust and scalable

program that will enable the supervision

of networked Uninterruptible Power

Supply (UPS) systems to be done at a cost

that is substantially lower than the cost of

using major network management system

platforms.

Intelligent Power Manager can carry

out a scan for all the UPS systems,

regardless of the vendor, using both XML

Web services and SNMP protocols. It also

discovers and manages other critical power

components, such as ePDU products,

shutdown modules, and environmental

sensors, to give administrators

comprehensive control of their protected

infrastructure.

‘Intelligent Power Manager is an

excellent productivity tool that gives IT

managers a global view of their power and

environmental devices, from any secure

personal computer on the network’, said

Mr Bernard Lee, Product Manager, Eaton

Power Quality Business Unit.

‘Th e fl exible and intelligent monitoring

of devices simplifi es management,

minimises response time, reduces time to

repair, and substantially increases uptime

- benefi tting the bottom line’, he added.

Th e feature-rich software presents a

consolidated view of the main operating

parameters of all UPS systems, which can

be confi gured easily, according to the type

of UPS, location, operating status, and

other user-defi ned parameters. Th rough

its colour-coded displays and customised

views, administrators can activate advanced

functions such as automatic shutdown of

unattended servers, automatic re-boot, and

system operation scheduling of multiple

devices over multiple locations. Th e

software also off ers the ability to organise

devices by several diff erent criteria such as

Internet Protocol (IP) address, application

type, or owner. Users can assign automatic

actions such as e-mail notifi cation of

power or environmental events, as well as

centralise alarms and maintain event logs

for preventive maintenance of the entire

installed equipment base. Moreover,

network management card setup and

maintenance is reduced by mass-upgrading

the fi rmware.

As part of Eaton’s PowerChain

Management solutions, Intelligent Power

Accurate determination of insulation moisture contentDIRANA, the DIelectric Response

ANAlyzer, from OMICRON, determines

in a simple and effi cient way, the moisture

content of liquid-fi lled transformers.

Accurate knowledge of the moisture

content is a crucial factor in the condition

assessment of power transformers. High

moisture levels accelerate insulation

decomposition, decrease dielectric

strength, and may cause bubbles to form

at elevated temperatures. Additionally,

the condition (water content) of the oil

is determined. DIRANA can also be used

for the condition assessment of bushings,

instrument transformers, cables, and

rotating machines. Other applications

include verifi cation of proper drying

for a new transformer at the factory or

confi rmation that the transformer is

properly dried out after fi eld assembly,

repairs, or oil processing.

Speed meets precision

DIRANA determines the moisture

content on the basis of Dielectric

Frequency Response (DFR). A special

feature of DIRANA is the combination

of the two measurement techniques -

Polarisation Current Measurement (PDC)

and Frequency Domain Spectroscopy

(FDS). Th is allows for accelerated

measurements, even in the very low

frequency ranges which are often required

for measurements on transformers that

are new, cold, and dry. Th e extended

measurement range of 5 kHz down to

50 μHz, allows DIRANA to discriminate

between moisture in the oil, insulation

geometry, and paper. Th e result is

independent of moisture equilibrium and

insulation temperature. By combining

the time and frequency domain methods

(PDC and FDS), DIRANA achieves

superior speed that halves conventional

measurement times. Measurements made

with DIRANA are claimed to be more

accurate than traditional oil sampling, as

compensation for equilibrium conditions

and the use of equilibrium diagrams are

no longer required.

Integrated expert knowledge

DIRANA's assessment is based on

a database containing data from

measurements of real oil-paper-insulation

systems with varying moisture content

and oil/paper ageing. On this basis, the

measurement results are automatically

analysed and the moisture content is then

classifi ed according to IEC 60 422 between

the extremes ‘dry’ and ‘extremely wet’.

Additionally, the software compensates

Dielectric Response Analysis with DIRANA.

for conductive ageing byproducts in the

oil and is therefore well suited for older

transformers.

New features

A new ‘Pre Measurement Check’ feature

analyses the capacitance, signal to noise

ratio, and noise current, to ensure

a successful test. Th e software also

recognises when suffi cient data has been

gathered and the test can be stopped.

Th erefore the measurement time can

be minimised. Training videos are now

available that discuss moisture analysis

and test set operation.

LED lighting from AZ E-lite Light Emitting Diodes (LEDs) are

energy-effi cient and long-lasting. LED

lights create less heat than traditional

lights, which means they last longer (up

to 50,000 hours which is 50 times more

than incandescent lights and fi ve times

more than fl uorescent lights) and save

up to 50% in electricity bills.

Th e global LED lighting market is

expected to grow exponentially with

increasing acceptance and adoption of

LEDs as a viable mainstream and green

Philips sports lighting at 2010 World Cup stadiumsSix out of the 10 stadiums that hosted

the recently concluded 2010 FIFA World

Cup South Africa soccer tournament,

were lit up with the ArenaVision

MVF404 fl oodlighting solution from

Philips. Th ey are the Soccer City

Stadium in Johannesburg where the

fi nal was held, Ellis Park Stadium in

Johannesburg, Royal Bafokeng Stadium

in Rustenburg, Moses Mabhida Stadium

in Durban, Peter Mokaba Stadium in

Polokwane, and the Nelson Mandela

Stadium in Port Elizabeth.

Th e ArenaVision MVF404

fl oodlighting solution has been developed

to allow for 10% more light and fewer

luminaires to be used, thereby saving

on costs, energy use, and maintenance.

With increased optical effi ciency, the

light distributed has minimal spill.

Th e new ArenaVision systems off er

easy lamp fi tting and replacement, full

IP65 compliance, a new safety knife

connector system, and an electronic hot-

restrike solution, while continuing to

off er all the benefi ts of its predecessor.

Ellis Park Stadium in Johannesburg.

Th e advanced and yet unobtrusive

lighting solutions from Philips helped

to enhance the viewing experience for

players, referees, spectators, and TV

viewers alike, bringing the spectacle and

emotion of the soccer games alive.

‘Light represents less than 1% of the

stadium/arena budget, but determines

99% of the eff ect seen on TV. It is vital

that our lighting systems accommodate

the stringent demands of the TV

broadcasting industry in capturing the

details and emotion of the sports for a

remote audience. But it does not stop

there. Th e ArenaVision systems also give

live spectators the best possible viewing

experience to clearly see what is going

on from every seat. And, as we all know,

every detail can be of great importance.

Good and unobtrusive lighting help

players and referees deliver the best

performance. It is for this reason that

Philips was chosen to light most of the

South Africa’s top stadiums’, said Mr

Jeroen Jansen, Philips Lighting’s General

Manager for Southern Africa.

In the Moses Mabhida Stadium, for

example, Philips supplied a total of 548

ArenaVision MVF404 2kW fl oodlights

to illuminate the soccer pitch to 2000

lux average vertical while the athletics

track is illuminated to 1000 lux average

vertical.

Th e fl oodlights are mounted on two

aluminum catwalks suspended by tie-

rods from the roof steelwork - one on

the east side and one on the west side.

Th e average height of these catwalks is

45 m above the playing fi eld.

In the event of power failure, 46 hot

restrike versions of the 548 fl oodlights,

provide safety lighting.

To further ensure maximum

performance of its lighting installations,

the fl oodlights were powered by diesel

generators during the World Cup

2010 tournament, with supply utility

ESKOM acting as the backup.

Philips also supplied general

lighting luminaires for the venues. For

example, at the Soccer City Stadium,

the company provided 1900 roof truss


News & Events

luminaires (TCW216 2xTL-D 58

W) to illuminate the underside of the

skin of the roof canopy; 60 upper tier

aisle lighting luminaires (MVF616 1

kW halogen fl oodlights) to illuminate

a part of the spectator seating; 1600

luminaires (TCW216 2xTL-D 18W) to

illuminate the roof catwalks on which

the fl oodlights are mounted; and 136

upper concourse column spotlights

(BBB451 3 x LED-K2) for aesthetic

lighting as well as offi ce and general

lighting.

Further, Philips used LED solutions

to light up a hotel where the Dutch

soccer team was staying.

Philips’ ArenaVision sports lighting

already equips more than half of the

world’s major football stadiums, and the

technology has been further improved

since the 2006 FIFA World Cup in

Germany.

Philips has been the leader in sports

lighting applications. For years, the

company has been the technical partner

of international sports federations.

Th rough these partnerships, Philips has

helped to draw up offi cial specifi cations

and guidelines for fl oodlighting in

sporting venues.

Ensuring glare-free lighting of the Centre Court at Wimbledon

Wimbledon 2010 was held from 21 June

to 4 July 2010 at the All England Lawn

Tennis Club.

Traditonally, the matches were played

during the day under natural light, and

they were interrupted when the level

of light deteriorated. Now, with the

installation of a retractable translucent

roof over the Centre Court at Wimbledon,

matches could be played at night with the

help of artifi cial sports lighting.

Th e GRAFIK 7000 system, from

Lutron Electronics, is used to control the

more than 120 light sources when the

retractable roof is closed, off ering accurate

and glare-free lighting of the Centre

Court.

Th e new system controls both direct

and indirect lighting sources. It is the fi rst

time that indirect lighting has been used

to illuminate such a high profi le sports

arena. Sixty of the indirect lights are fi tted

blanket of overlay light.

Th e Lutron system can be programmed

in two operating modes – Championship

and non-Championship. Th e

Championship mode is pre-programmed

and fully automated to exacting

requirements, to ensure that players have

the minimum of distractions. Th e non-

Championship mode is more fl exible,

with a number of preset scenes being

possible for various training and spectator

conditions. Th e conceptual design of

the sports lighting was accomplished by

global engineering design company M-E

Engineers.

‘In designing the sports lighting for the

retractable roof on Wimbledon’s Centre

Court, we were presented with a unique

challenge - the sliding roof was to be far

lower than at any other major professional

venue in the world, creating a potential

problem with glare to the players’, said

Mr Corey Berhost, Associate Director,

M-E Engineers.

‘Working with the architects and

the client, we introduced the technique

of indirect sports lighting. What was

discovered was that by refl ecting some of

the light off the roof itself, we could add a

layer of diff use light to blanket the court

and this reduced the need for the quantity

of glare-producing direct luminaires.

Everything from the selection of a fabric

roof membrane to the colour selection

of the moving roof trusses, played a

major role in the symbiosis of the system

integration’, he added.

A key requirement was meeting the

high luminance levels required by TV

companies with the high-defi nition

coverage of the event. Th e All England

Lawn Tennis Club also specifi ed an ‘easy

to use’, fail-safe way of controlling the

lighting whether the roof was open or

closed.

Th e GRAFIK 7000 control system

provides the centralised lighting control

solution. With multiple processor capacity

(with up to 32 processors), 16,384 zones

and 6,144 Control Station Devices, the

system is well placed to cope with stadiums

of any capacity. At Wimbledon Centre

Pioneering tidal power moves closer to realitySurrounded by strong seas and winds,

Scotland has 25% of Europe’s tidal

resources and 10% of its wave potential.

One of the biggest energy suppliers,

ScottishPower Renewables, wants to

convert the natural power into clean

electricity, with banks of gigantic, high-

tech, underwater turbines turning the sea’s

tidal movement into green energy.

It is developing a system that will be

the largest demonstration tidal power

project in the world, putting the company

at the forefront of this activity, globally.

By building at least 40 underwater

turbines in various places off the Scottish

coast, the tidal farm sites would have a

combined output of 60 megawatt (MW),

enough to power 40,000 homes in

Scotland and Northern Ireland.

It is thought that, if fully accessed,

Scotland’s tidal resources could contribute

to more than 30% of its energy demand.

One of the benefi ts of tidal power is that

it is extremely predictable compared with

other forms of green energy.

Experts believe that thousands of

jobs could be created in this sector as the

technology is exported across the world,

with an estimated market of some 40

billion pounds. Scotland's government

recently stated that kick-starting the sector

is vital if a signifi cant industry, based in

Scotland, is to be created, and the long

term renewables targets are to be met.

Th e high-tech, underwater turbines

are 30 m tall and can work as deep as 100

m. Th e 20 m blades would turn at least

10 m below the surface to avoid shipping.

Th e energy zones would be off -limits to

trawlers for safety reasons.

According to Mr Keith Anderson,

Director, ScottishPower Renewables,

‘Tidal power is completely renewable,

being driven by the gravity of the sun and

moon, with no carbon dioxide emissions,

plus the added benefi t of being entirely

predictable’.

‘Th e rapid technological advance of

tidal power has been startling and is now

allowing us to progress plans for substantial

projects delivering major environmental

and economic benefi ts’, he added.

ScottishPower Renewables’ partner in

the scheme is Hammerfest Strøm UK, a

subsidiary of the Norwegian tidal power

developer Hammerfest Strøm.

Hammerfest has received a grant of

3.9 million pounds from the UK’s Carbon

Trust for the construction and testing of a

1 MW tidal power device off the Orkney

islands, northern Scotland.

Hammerfest Strøm’s underwater

turbines are mounted on the sea bed to

capture ‘tidal stream’ power, which is

diff erent to ‘tidal barrage’ power, because

there is no need to impound the water.

Th is is expected to bring signifi cant

environmental advantages by avoiding

impacts on sensitive inter-tidal zones

around coasts. In the future, arrays of

multiple devices are anticipated, that

could each generate 50 MW to 100 MW.

Th e tidal turbine is expected to be

fully operational near Orkney by 2011.

Hammerfest Strøm UK has already

completed the design and pre-engineering

and is now tendering for fabrication

and installation. After a test period, the

company will work with ScottishPower

Renewables which has plans to install the

device as part of a 10 MW tidal power

array off the coast of Islay, south-west

Scotland, by 2012.

Hammerfest Strøm's device is

designed, based on a 300 kW prototype

that has been installed in Kvalsundet,

Norway, for the last six years. Th e

prototype device was the fi rst turbine in

the world to convert kinetic energy in

tidal waters to electricity and deliver to

the grid in 2004.

ScottishPower’s Mr Anderson said,

‘We fi rmly believe that the tidal turbine

developed by Hammerfest Strøm is the

most advanced and rigorously tested

device anywhere in the world’.

‘Th e grant from the Carbon Trust

will enable the fi rst deployment of the

turbine in Scottish waters, where we have

ambitious plans to further utilise the

device at a number of locations to take

advantage of the fantastic tidal resources

that Scotland has to off er’, he added.

Th e tidal power resource is estimated

at some 150 billion kWh/yr globally

(representing capital investment of about

40 billion pounds sterling). Th e UK share

has been estimated at 13 billion kWh/yr

and more than 80% of this is located in

Scottish waters.

ScottishPower Renewables is part

of Iberdrola Renovables, a Spanish

multinational corporation, which is

the largest wind energy company in the

world, with an installed capacity of almost

11,000 MW at the end of 2009, and a

pipeline of 57,400 MW. ScottishPower

Renewables had more than 800 MW of

installed capacity at the end of 2009, and

a pipeline of 5,115 MW.

World Wind Energy Award 2010 given to IRENAOn the occasion of the 9th World

Wind Energy Conference 2010, the

Board of the World Wind Energy

Association (WWEA) decided to give

the World Wind Energy Award 2010

to the Founding Member States of

the International Renewable Energy

Agency (IRENA) and handed it over

to IRENA’s Interim Director General,

Ms Hélène Pelosse.

The World Wind Energy Award

has been given to honour all

Founding Members for the founding

of IRENA.

The creation of IRENA can be

seen as the most important decision

ever taken on the global level in

favour of renewable energy.

The founding of IRENA sent

out a very strong signal to the world

community that renewable energy

will have to play and will play a key

role in the future energy supply all

over the world.

With the award, WWEA has also

indicated that it is committed to

working closely with IRENA and will

continue to give its full support.

IRENA has already 145 members

and the ratification process is going

on rapidly.

WWEA says that it is pleased that

the crucial mark of 25 ratifications has

now been reached. This is expected

to make IRENA a legal entity by the

beginning of July.

With this impressive and fast

progress, IRENA is an example of the

successful creation of an international

governmental body.

In spite of a lot of opposition,

the world community convincingly

committed to the implementation

of renewable energy. The founding

of IRENA was a very long, often

difficult process, and many obstacles

had to be overcome.

Not everybody, in the traditional

energy sector and beyond, shared

the enthusiasm that the initiators of

IRENA had been showing for many

years. The WWEA has been one of

the initiators and one of the strongest

proponents since its own foundation

in 2001.

Officially launched by the

Governments of Germany, Denmark,

and Spain, in 2008, the initiative to

create IRENA has found many more

supporters than most people had

expected, at a breathtaking pace.

These countries and all those

countries that followed to support

IRENA showed extraordinary

leadership and passion by overcoming

huge internal and external barriers.

The Founding Member States

of IRENA, with all their authority,

have initiated a new and innovative

direction.

It is a direction that will lead

into a future where some of the most

pressing problems which mankind is

facing today, such as energy scarcity,

climate change, and equal as well as

fair access to energy, are overcome.

IRENA’s Founding Members

have indicated with their action

that they want to break the vicious

circle of increasing dependency on

limited fossil resources, and replace

it with energy independence by using

domestic renewable resources.

IRENA’s creation gives the

opportunity to create the long-due

access to energy for billions of people

that so far have been left out.

WWEA sees the creation as a

milestone to introduce wind energy

and other renewable energies on a

broad basis and on a large scale.

It will be important that the

working scope of IRENA be as

broad as possible, involving the

broad diversity of stakeholders and

applications in renewable energy.

Small, rural communities as well as

large cosmopolitan areas will benefit

equally.

WWEA however believes that

building the operational capacities

and capabilities of IRENA is an

enormous task which requires huge

efforts.

WWEA said that in these

circumstances, it is encouraging to

see the leadership and drive that

IRENA’s Interim Director General

Ms Hélène Pelosse and her dedicated

team have shown.

The creation of IRENA has raised

high expectations all over the world.

WWEA says that it hopes and

expects the World Wind Energy

Award 2010 to encourage the

Member States of IRENA to continue

the present path and without any

hesitation follow it to its successful

implementation.

WWEA also says that it hopes

and expects Ms Hélène Pelosse

and the whole IRENA Staff to feel

encouraged to continue the work

which has just started but which

will be of crucial importance for the

future of mankind.

World Wind Energy Award

ABB wins order for offshore wind power connectionABB, a leading power and automation

technology group, has won an order

worth around US$ 700 million, from

the German transmission grid operator,

transpower, to supply an 800 MW power

link that will connect more off shore wind

farms in the DolWin1cluster, located in

the North Sea, to the mainland German

grid.

ABB will deploy its innovative and

environment-friendly HVDC Light

(high voltage direct current) transmission

technology to transmit power from the

400 MW Borkum West II wind farm and

other wind farms to be developed nearby.

Th is is the second HVDC Light

off shore wind connection supplied by ABB

in Germany, the fi rst being the BorWin1

project, the most remote off shore wind

farm in the world.

For the DolWin1 project, the wind

farms will be connected to an off shore

HVDC converter station which will

transmit electricity to the onshore HVDC

station at Dörpen, on the northwest coast

of Germany via 165 km of underwater and

underground DC cables. Th e Dörpen/

West converter station will in turn feed

AC power to the mainland grid.

Th is is the largest power transmission

order in ABB’s history. At 320 kV, this

will be the highest voltage level at which

extruded cable is used in an HVDC

application.

ABB will be responsible for system

engineering, including design, supply,

and installation of the off shore platform as

well as the off shore and onshore converter

stations, and will also supply and install

the sea and land cable systems.

‘Off shore wind power is becoming a

key source of large-scale renewable energy

and is making a vital contribution to the

eff ort of lowering environmental impact’,

said Mr Peter Leupp, head of ABB’s Power

Systems division.

‘ABB has state-of-the-art transmission

technologies for integrating renewable

energy sources effi ciently and ensuring

grid reliability and stability’, he added.

HVDC Light transmission systems

off er environmental benefi ts such as neutral

electromagnetic fi elds, oil-free cables, and

compact converter stations. It is a solution

for connecting remote off shore wind

farms to mainland networks, overcoming

distance limitations and grid constraints,

while ensuring robust performance and

minimal electrical losses.

Scheduled to be operational in 2013,

this network of off shore wind farms is

expected to avoid three million tons of

carbon dioxide emissions per year, which

is the amount produced when generating

an equivalent amount of energy from

fossil fuels. Germany currently meets

about 8% of its electricity requirements

with wind power, and expects to double

that by 2020.

ABB commissions world’s longest and most powerful transmission link ABB has achieved another signifi cant

milestone with the commissioning of the

Xiangjiaba-Shanghai project in China, the

world’s fi rst UHVDC (ultrahigh voltage

direct current) transmission link to go

into commercial operation. ABB was the

main technology supplier to State Grid

Corporation of China (SGCC) and the

project was completed in 30 months, one

year ahead of schedule.

Th e ±800 kV Xiangjiaba-Shanghai

UHVDC link has the capacity to transmit

up to 7,200 MW of power from the

Xiangjiaba hydropower plant in southwest

China to Shanghai, the country’s leading

industrial and commercial centre about

2,000 km away. Th e new link is able to

meet the electricity needs of about 24

million people, and sets a new benchmark

in terms of voltage levels and transmission

capacity, superseding the 600 kV Itaipu

transmission line in Brazil, which was also

delivered by ABB.

‘Th e 800 kV UHVDC will play an

important role in providing China with

access to remote renewable energy, a key

focus area for us’, said Mr Zheng Baosen,

Executive Vice President, SGCC.

‘We are extremely pleased with the

support and co-operation of ABB and

the local Chinese suppliers during the

execution of this project, which enabled

its completion in record time’, he added.

Th e high-capacity power link comprises

a single overhead line and occupies less

space than the existing system. Moreover,

transmission losses on the new line are

under 7%, again considerably less than

the existing 500 kV system. Th e electricity

saved is equivalent to the power needs of

around one million people in China.

‘Th e Xiangjiaba-Shanghai link sets a

new standard in ultrahigh voltage power

transmission and underlines ABB’s global

leadership in HVDC technology’, said

Mr Peter Leupp, head of ABB’s Power

Systems division.

‘We congratulate State Grid

Corporation of China on this remarkable

achievement and acknowledge the

excellent cooperation and support of all

our local partners’, he added.

As part of the turnkey project, ABB

was responsible for overall system design

and supplied the main equipment. Th e

scope of delivery included 28 high- and

ultrahigh- voltage converter transformers,

10 of which were delivered from Sweden

and the rest manufactured with ABB

components and technology, in local

partnership. Other key products delivered

include thyristor valves, DC and AC

switchyard equipment and the newly

developed DCC800 HVDC control

system.

UHVDC transmission is a

development of HVDC pioneered by

ABB more than 50 years ago. Th e new

technology with an advanced control

system represents the biggest capacity

and effi ciency leap in power transmission

systems in more than two decades. It is

particularly suitable for vast countries

like China and India, where consumption

centres are often located far from power

sources including renewables.

Mitsubishi Electric launches NEXIEZ elevator series for the global marketMitsubishi Electric Corporation recently

announced that it has launched the

NEXIEZ series of elevators for the global

market. Th e series off ers a load capacity

ranging from 450 kg to 1,350 kg and a

rated speed of 60 m/min to 105 m/min,

and helps users reduce carbon dioxide

emissions through the high energy-

effi ciency resulting from the compact,

lightweight designs. Th e NEXIEZ

series is also designed to refl ect various

preferences and lifestyles to meet the

needs of customers worldwide.

Th e NEXIEZ series, positioned as

Mitsubishi Electric’s next global fl agship

elevator series, will be manufactured

by Mitsubishi Elevator Asia Co Ltd in

Th ailand, and shipped to other countries

in Southeast Asia, the Middle East, and

other areas worldwide.

In response to a growing demand for

elevators with reduced environmental

impact, the NEXIEZ series features

a permanent magnetic (PM) gearless

traction machine that hoists the ropes

using PM motors. Th e motors incorporate

technology devised by Mitsubishi

Electric, which achieves size reduction

and energy-effi cient operations.

OPTIONAL SPECIFICATIONS

Regenerative converters

Elevators are usually operated by

traction machines which carry the

elevator cars up and down. When a

car travels down bearing a load heavier

than the counterweight, or when a car

moves up bearing a load lighter than

the counterweight, the motor spins in

reverse and is operated as a generator.

Th e electricity generated by this

operation was previously wasted as heat,

but by using regenerative converters, the

electricity can be eff ectively utilised for

other equipment inside the building.

According to research conducted by

Mitsubishi Electric, building owners

can consume up to 35% less energy in

elevator operations and therefore reduce

annual carbon dioxide emissions when

incorporating regenerative converters.

LED lighting and LED hall lanterns

For ceiling lights and hall lanterns,

customers can select LED lighting

which can reduce energy consumption

by approximately 50% or more and

therefore reduce annual carbon dioxide

emissions compared to previous forms

of illumination. LED also has a long

lifespan, enabling building owners to

reduce operational cost.

New designs that suit each market

Mitsubishi Electric has conducted

market research and prepared designs to

suit the tastes of each market. 15 ceiling

design variations including two with

LED lighting, can be used with a variety

of decorative lighting boards. Six new

etching patterns in addition to the current

designs for the interior walls of elevator

cars and hall designs include geometric

patterns with modern arrangements and

sophisticated atmosphere created with

stainless steel in gold and other colours.

For hall lanterns, fi ve new choices that use

LED will be available.

Regenerative converters used in Mitsubishi Electric’s new NEXIEZ series can help building owners to reduce energy consumption in elevator operations. Th e new series features elevator designs to suit diff erent markets.

approximately 20 leading Asian business

capitals will be compared in terms of their

environmental sustainability. Th e cities

will be assessed in eight environmental

categories, including energy supply

and CO2 emissions, transport, water,

sanitation, and green governance.

According to Siemens, the Asian Green

City Index is the fi rst known attempt to

analyse and compare the environmental

performance of Asian cities and their

eff orts to improve sustainability.

Publication of the study is planned for

the end of 2010.

Th e ranking will cover cities from 11

Asian countries – China, India, Indonesia,

Japan, Malaysia, Pakistan, the Philippines,

Singapore, South Korea, Th ailand, and

Vietnam. Th e fi nal selection of cities will

be based on data availability.

‘With the Asian Green City Index,

the Economic Intelligence Unit and

Siemens are covering new ground. So

far, no other study of this scope has been

done for Asia’, said Mr Stefan Denig who

is leading this project at Siemens.

Th e study will be part of the Green

City Index series which sets out to

compare the environmental performance

of cities in diff erent regions of the world.

Following the success of the European

Green City Index, a study comparing

the environmental performance of 30

major cities from 30 European countries,

Siemens is now sponsoring similar studies

for Asia, Africa, and Latin America.

‘Th e results of the study will help the

cities to better understand and tackle

their specifi c environmental challenges’,

said Mr Lothar Herrman, CEO, ASEAN

Cluster, Siemens.

‘It will enable city stakeholders to

make more informed decisions about how

to reduce their environmental impact

by, for example, making their power

supplies, traffi c systems, and buildings,

more energy-effi cient and eco-friendly’,

he added.

Th e cities will be assessed in eight

environmental categories - energy supply

and CO2 emissions, transportation,

buildings and land use, water, sanitation,

waste, air quality, and green governance.

At the same time, the study will highlight

best-practice projects to enable cities

to learn from one another. As an

independent partner, the EIU will ensure

the objectivity of the research.

Over the past few years, Siemens has

been focusing on urban challenges and

urban sustainability, and has conducted

various studies on these topics in

cooperation with independent research

partners. On the occasion of the World

Cities Summit 2010 from 28 June to

1 July 2010 in Singapore, Siemens

published its latest study ‘ICT for City

Management – Using information and

communications technology to enable,

engage and empower city stakeholders’.

In recent years, a number of other reports

have been published including ‘Megacity

Challenges’ (2007), ‘Sustainable Urban

Infrastructure – Edition London’ (2008)

and the ‘European Green City Index’

(2009).

Cities must take a leading role in

climate protection. Th ey are responsible

for 80% of the world’s CO2 emissions

and consume three-quarters of its energy.

‘Urbanisation and climate change are

two megatrends we can help address with

our valuable and innovative solutions’

explained Mr Herrmann.

According to Siemens, it has the

world’s largest environmental portfolio

of energy-effi cient and climate-friendly

technologies. In fi scal 2009, the company

generated about 23 billion euros in

revenue from products and solutions in its

environmental portfolio – approximately

30% of the company’s total annual

revenue.

In Singapore, Siemens is providing

technological solutions to ensure the

sustainable development of the island

state, from clean and effi cient energy,

through its installed advanced gas turbines

in power plants, to energy-effi cient

building automation systems such as the

one in City Square Mall. Siemens is also

working with the authorities to provide

sustainable energy solutions such as smart

grid solutions and is also a major partner

of PUB, the national water agency, in the

recycling and production of clean water.

Elevators and escalators for Shanghai projectMitsubishi Electric Corporation recently

announced that it had received an order

for 127 elevators and escalators to be

installed in the Shanghai JingAn Kerry

Centre, a large complex of buildings

under construction in Shanghai, China.

Th e order is worth approximately 1.5

billion Japanese yen, and shipments will

be made from September 2010 through

July 2011.

Th e order was received from

Shanghai JiXiang Real Estate Co Ltd, a

joint-venture between Kerry Properties

Limited, a Hong Kong-based real estate

developer, and Shangri-La Asia Limited.

Th e twin towers of the Shanghai JingAn

Kerry Centre will house offi ces and

commercial facilities.

Th is order is for 42 high-speed

elevators capable of speeds of 120 to

480 m/min, 37 low-speed elevators that

can travel at 60 m/min to 105 m/min,

and 48 escalators.

To achieve energy savings, all of the

high-speed elevators and 30 of the low-

speed elevators, will feature an energy-

saving power-regenerative function

which allows the elevator to effi ciently

reuse energy generated from elevator

operation, contributing to energy

savings and reducing environmental

impact.

Th e elevators and escalators will be

manufactured by Mitsubishi Electric’s

Inazawa Works in Japan, Mitsubishi

Elevator Asia Co Ltd in Th ailand, and

Shanghai Mitsubishi Elevator Co Ltd in

Shanghai, China.

Siemens releases study on how ICT can be used to empower city stakeholders In the fi ndings of a recent study sponsored

by Siemens and conducted by the

Economist Intelligence Unit (EIU) on the

use of information and communications

technologies (ICT) for city management,

it was found that ICT has become the

life blood of all cities, enableing them

to be competitive and provides new

ways for cities to overcome some of their

most pressing challenges such as traffi c

congestion, environmental protection,

and the need to optimise infrastructure.

It also empowers citizens across the world

to get involved in devising solutions to the

challenges of urban living. Approximately

2,800 public offi cials, business executives,

and citizens, in 15 cities in 12 countries,

were interviewed. Th e results were released

at the World Cities Summit in Singapore

on 28 June 2010.

Enabling competitiveness and

environmental consciousness

Th e study found that a strong Internet

network and an ICT savvy workforce

are crucial for a city’s competitiveness.

Some 77% of businesses globally said an

improved broadband network would have a

signifi cant impact on city competitiveness,

making it the most important ICT feature

for attracting private sector investment.

Another signifi cant fi nding is

that ICT can infl uence the behaviour

of citizens and businesses towards

environmental conservation by giving

them more information about their usage

of resources, such as energy and water.

Globally, 74% of citizens and 61% of

businesses claim they would likely change

their consumption patterns if they can

have more information about their usage.

However, they admitted that the right

fi nancial incentives need to be in place as

well, to encourage environmentally sound

behaviour.

‘One of the most striking fi ndings

is the fact that ICT has become a basic

utility, like water and electricity, for all

cities’, said Mr Klaus Heidinger, Head of

Global Center of Competence for City

Management at Siemens IT Solutions and

Services in Singapore.

‘Th is study shows that there is a

lot of potential for ICT initiatives like

smart grid, which will enable citizens

and businesses to better manage and

optimise their electricity usage, improve

energy-effi ciency, and encourage the use

of renewable energy sources. As one of the

world’s leading infrastructure providers,

Siemens is uniquely positioned to assist

cities tackle their urban development

challenges. Th is is not only with

infrastructure improvements, but also the

integration of intelligent ICT solutions

into all parts of a city’s infrastructure

– from municipal transport to public

security’, added Mr Heidinger.

Engaging all stakeholders in a city

Th e study also revealed that businesses

and citizens are looking at e-government

initiatives to improve their interaction

with public offi cials. More than 89% of

businesses picked ‘higher effi ciency’ as an

expected key benefi t of using ICT in the

delivery of public or regulatory services.

Similarly, citizens felt that e-government

initiatives would have a major or signifi cant

impact on their quality of life.

While the benefi ts of e-government

initiatives are clear, stakeholders are

divided on the barriers for their adoption.

Businesses said that public offi cials could

be more open to adopting online public

services. On the other hand, a majority of

citizens felt that public offi cials could be

more responsive to their online feedback.

In contrast, these offi cials cite citizens’

resistance to online transactions as one of

the greatest challenges to e-government.

Overall, this fi nding suggests that

e-government initiatives can bring a lot

of value to cities. To derive maximum

value, all stakeholders will need to work

together.

Empowering citizens in providing

solutions for their cities

Th e study also found an increasing

trend where citizens, armed with data

from offi cial sources, video and other

information, are coming up with smart

phone and other mobile applications to

make city living easier and more enjoyable.

Public offi cials therefore may have to take a

closer look at embracing ICT to empower

their citizens to play a signifi cant role in

shaping their own cities.

For example, in Portland, Oregon,

USA, city offi cials have launched a

competition called CivicApps for

residents to create applications from

data that includes information on parks,

transportation, and building permits. And

in New York City, USA, an iPhone user has

taken a government census of more than a

million trees to create an application that

allows fellow users to point their devices at

any tree to fi nd out its size and species.

Th e study

Th e study ‘ICT for City Management’

was conducted by EIU from March to

April this year, and involved 240 public

offi cials, 2250 citizens, and 300 business

executives, across the 15 cities – Abu

Dhabi, Berlin, Buenos Aires, Copenhagen,

Delhi, Dubai, Istanbul, London, Madrid,

Mumbai, Munich, New York, Shanghai,

Singapore, and Vienna.

Collaboration on renewable energy managementTh e ZigBee Alliance and the SunSpec

Alliance recently announced an

agreement to collaborate on defi ning

standards for renewable energy and

microgrid management using the ZigBee

Smart Energy version 2.0 standard. Th e

ZigBee Alliance is a global ecosystem of

companies creating wireless solutions

for use in energy management, and

commercial and consumer applications,

while the SunSpec Alliance was formed

to accelerate the growth of the renewable

energy industry through standardisation

of monitoring and management interfaces

for energy system components. Th is

collaboration will bridge the gap between

distributed generation using renewable

energy resources and the Smart Grid.

Green features of CleanTech OneJTC Corporation is developing CleanTech

Park (CTP) as the choice location and

epi-centre for R&D as well as business

and supporting activities in clean

technologies, sustainable development,

and urban solutions, rather than as just a

home for cleantech companies.

CTP will serve as a large-scale

integrated ‘living laboratory’ for test-

bedding and demonstration of system-

level clean technology products and

solutions, especially those catering to the

tropics, before they are commercialised

for the market.

Th e masterplan of CTP was

developed with the aim of optimising

the natural environmental heritage, to

create a conducive, eco-friendly address

for the cleantech community. Th e

emphasis is on the eff orts to maintain a

long-term sustainable balance between

the commercial needs of CTP and the

preservation of the site’s biodiversity.

CleanTech OneCleanTech One (CTO), the first

building which JTC is developing

at CTP, will serve as a showcase for

sustainability.

USE OF SOLAR ENERGY

Solar-powered solutions

Solar panels based on the proven

monocrystalline and polycrystalline

PV cells, as well as on the new thin

film and nano-structured printed PV

technologies, will be installed over

2,600 sq m of roof space.

Solar thermal collectors will also

be placed on the roof to power a

dehumidifier attached to the air flow

ducts in the airconditioner units in

CTO. There will therefore be no need

for additional energy to dry the humid

air by extracting the condensation

during the cooling process, as is the

case with conventional airconditioning

systems.

Hydrogen fuel cell plant

A 1 MW integrated hydrogen fuel

cell plant will be test-bedded at

CleanTech One. Biomass will be used

as the feedstock for the generation

of hydrogen. In the first step, wood

chips, plant waste, and other cellulosic

materials, will be converted to syn-gas

(a mixture of hydrogen and carbon

monoxide) via a reformer.

The syn-gas will then pass through

a pressure swing adsorber, where the

carbon monoxide will be removed.

The purified hydrogen will then

enter a Proton Exchange Membrane

(PEM) fuel cell plant comprising one

thousand 1 kW fuel cells connected in

parallel and controlled by a network of

microcomputers.

Bio-digester

A 10 t bio-digester system will be

installed to decompose food waste

generated within CTP. With the help

of micro-organisms, the food waste will

go through a rapid aerobic digestion

process which leaves water and carbon

dioxide as end-products.

CTO will serve as a showcase for sustainability.


News & Events

ENERGY-EFFICIENCY

Building orientation

Th e building will be oriented in a direction

that will minimise heat gain and optimise

energy-effi ciency, that is, it will assist

in minimising the Envelope Th ermal

Transfer Value (ETTV).

Perimeter corridors will be built to

act as a buff er between the façade and the

units, which will reduce heat gain.

Th e Sky Trellis

CTO will incorporate JTC’s innovative

Sky Trellis - a ‘green’ canopy between

adjacent buildings. Th e canopy will lower

the heat build-up on the building façade

as well as in the immediate area between

the buildings. With the lowering of

ambient heat, the energy consumption of

the building is also reduced. Th e lowered

demand for airconditioning will ultimately

translate to savings in business costs.

Natural ventilation

Natural ventilation will be maximised

for corridors, lobbies, open spaces, and

staircases. A wind wall will channel wind

through the two tower blocks to improve

air circulation and the thermal comfort of

occupants.

Lighting

According to JTC, CTO will be the fi rst

building in Singapore to fully employ

LED lighting for all its indoor and

external lighting requirements. Lights

will dim depending on the intensity of

sunlight in the room, thereby ensuring a

more effi cient utilisation of energy.

Airconditioning system

Studies have been done to fi nd out the

needed specifi cation of the airconditioning

units. Th is is to ensure that there will not

be overcapacity leading to wastage of

energy. Th is will be the main criteria in

the design and selection of the system.

Further, bends and turns in the ACMV

ductwork, will be minimised.

WATER EFFICIENCY

Water conservation

Grey water from wash basins and

condensate from the Air Handling Units

(AHUs) will be recycled for non-potable

reuse such as irrigation and fl ushing of

toilets.

Stormwater harvesting

Stormwater will be harvested on the

rooftops with minimal use of pumps,

and also harvested in bio-retention ponds

within the perimeter of the buildings.

ENVIRONMENTAL PROTECTION

Usage of recycled materials

External works such as the construction of

roads, sewers, and drains, will utilise eco-

concrete, made of materials like recycled

concrete aggregate and ground granulated

blastfurnace slag (GGBS).

Reducing and reusing construction

waste

Soil excavated during construction will be

retained for reuse in planting operations.

Formwork will also be reduced where

possible to decrease construction waste.

Maintaining the green cover

Space on the surfaces of the building

facing the atrium will be allocated for

greenery. Apart from that, pockets of sky-

gardens will also be created on all fl oors

above ground, to replace that lost due to

development.

Space will be allocated on the surfaces of the building, for greenery.

Recognition for contributing to cleaner waters and sustainabilityPUB, the national water agency, recently

honoured 14 developments with the

inaugural ABC Waters Certifi cation.

Launched by Senior Parliamentary

Secretary for the Environment and Water

Resources, Dr Amy Khor, in conjunction

with Singapore International Water Week

2010, the ABC Waters Certifi cation

scheme recognises the eff orts of the private

and public sectors in creating a sustainable

and more liveable city through integrating

the ABC Waters (Active, Beautiful, Clean

Waters) concept in their developments.

Th is is done by integrating natural

elements, known as ABC Waters design

features, which help treat storm water

(rain water) closer to source, in a holistic

manner. At the same time, these features

such as rain gardens, cleansing biotopes,

bio-retention swales, and constructed

wetlands, optimise land use as they also

achieve multiple aims of helping to slow

down the fl ow of rain water, beautify

urban spaces, create new community focal

points, and enhance biodiversity.

Th e certifi cation scheme is built

around four main categories – Active,

Beautiful, Clean, and Innovation.

Mr Tan Nguan Sen, Director of

Catchment and Waterways, PUB, said, ‘By

next year, two-thirds of Singapore will be

water catchment. Storm water treatment

on every possible surface that rain falls on,

will be even more important. ABC Waters

design features can be applied in a variety

of ways to urbanscapes, architectural

structures, open plazas, as well as roads

and pedestrian walkways, and we

encourage our partners to play a part in

keeping our waters clean by incorporating

these features island-wide’.

Last year, the ABC Waters Design

Guidelines, a handbook, was introduced

for industry professionals to incorporate

ABC Waters design features into their

developments.

Th e ABC Waters Certifi cation scheme

takes it one step further by recognising

the eff orts of developments which meet

certain standards in fulfi lling the ABC

Waters concept. Organisations will also

be able to market their developments as

‘ABC Waters certifi ed’.

Mr Sng Cheng Keh, Deputy Chief

Executive Offi cer (Building), Housing &

Development Board (HDB), said, ‘HDB

houses over 80% of Singapore’s population.

We have a key role to play in supporting

Singapore’s commitment to sustainable

development. Over the years, we have

been driving sustainable development

eff orts in our projects. We are happy to see

fi ve of our projects ABC Waters Certifi ed

today. On top of recognising our eff orts

in promoting clean waters and caring for

precious water resources, it spurs us to

continue with our work to make public

housing in Singapore a world-class model

for sustainable development’.

Mr Tan added, ‘Th e ABC Waters

Certifi cation thus provides an incentive to

encourage public and private developers

to contribute to cleaner waters and a more

sustainable way of living’.

Expo Asia 2010 (BEX Asia 2010), from

13 to 15 September 2010, organised by

Reed Exhibitions. All the three events will

be held at Marina Bay Sands, Singapore,

and are part of the 2nd Singapore Green

Building Week.

Singapore’s green building movement

crossed another signifi cant milestone when

SGBC was unveiled as an Established

Member of the World Green Building

Council (WorldGBC) network at its

Annual General Meeting on 19 March

2010, and also won hosting rights for the

WorldGBC International Congress 2010,

the marquee event in the international

body’s calendar.

Representing Singapore at the

WorldGBC, SGBC is instrumental in

articulating the country’s green building

interests and leveraging on the wide

resource of international expertise that the

WorldGBC provides.

Th e WorldGBC International

Congress is an annual forum for

representatives from the diff erent Green

Building Councils around the world to

meet and discuss objectives, policies, and

developmental strategies. It also brings

together infl uential stakeholders from

various related industries and international

sustainable development experts.

Minister for National Development

and Founding Patron of SGBC, Mr Mah

Bow Tan, commended the council for its

role in raising Singapore’s profi le in the

area of global sustainable development.

‘Th e Singapore Green Building Council

is an example of how the private and

public sectors can work together to drive

Singapore’s environmental sustainability

strategy. I am heartened at the progress

the council has made internationally, and

would like to encourage the members to

keep up the good work’, said Mr Mah.

Founding President of SGBC, Er.

Lee Chuan Seng added, ‘Th e impetus

to move Singapore towards sustainable

building rests on positive linkages

between private and public stakeholders.

We have demonstrated in a short time

that sustainability can be given more

focus by companies in the building sector.

I am confi dent that SGBC will continue

to make progress in product certifi cation

as well as to build its global brand’.

SGBC has also entered into a long-

term partnership with REED Exhibitions,

the organisers of Build Eco Xpo Asia

(BEX Asia), to deliver a dedicated trade

event for the industry, that has a strategic

focus on bringing green building to the

forefront of the industry’s needs. BEX

Asia is a platform which allows exhibitors

to present their products and educate

potential customers on the benefi ts of their

solutions. Last year, at BEX Asia 2009,

over 200 participating exhibitors from 21

countries reached out to more than 6,400

visitors from around the region.

SGBC

Th e inauguration of SGBC opens

a signifi cant chapter in Singapore’s

commitment towards creating a

sustainable built environment. It is an

industry-led initiative which works

towards convergence of all stakeholders

in green building on a common resource-

and knowledge- base.

SGBC’s mission is to propel Singapore’s

building and construction industry

towards environmental sustainability

by promoting green building design,

practices, and technologies; integrating

green building initiatives into mainstream

design, construction, and operation of

buildings; as well as enhancing capacity

and professionalism to support wider

adoption of green building development

and practices in Singapore.

Its work will complement the

government’s eff orts to accelerate the

greening of Singapore’s buildings by

2030, while, at the same time, providing

opportunities to share knowledge with

other countries in its climatic zone.

Th e SGBC membership is open to

developers, contractors, manufacturers/

suppliers, engineers, architects,

institutions/associations, agencies,

and individuals concerned with or

interested in transforming Singapore’s

built environment towards a sustainable

future.

POWER-GEN Asia 2010 and Renewable Energy World Asia 2010POWER-GEN Asia 2010, the region’s

premier conference and exhibition for

the power generation and transmission

and distribution industries, will be held at

Marina Bay Sands, Singapore, from 2 to 4

November 2010.

In its 18th presentation this year,

POWER-GEN Asia 2010 will be part

located with Renewable Energy World Asia

2010, the event dedicated to the rapidly

developing renewable and sustainable

energy sector. Both the events are being

organised by PennWell Corporation.

Th e power generation industry in

Singapore has transformed signifi cantly

over the past few years. Beyond moving

towards the increased use of combined-

cycle gas turbines, companies have also

increasingly adopted co-generation and

tri-generation technologies, making

the electricity generation cleaner, more

effi cient, and responsive.

Singapore is one of the pioneers in

the deregulation of the electricity market.

Th e divestment of the state-owned power

generation companies has resulted in the

entry of leading global energy players.

Th e electricity grid in Singapore is

already among the best in the world, yet

eff orts do not stop there. Improving two-

way communication between utilities

and consumers is on the agenda, with

the introduction of an Intelligent Energy

System (IES) pilot project which seeks to

test and evaluate smart grid applications

and technologies.

Th ese issues, case studies, and

technologies, will be amongst many other

regional challenges and opportunities

that will be discussed during the 3-day

conference programme at Marina Bay

Sands.

POWER-GEN Asia 2010 has

launched its preliminary conference

programme, with over 50 conference

sessions, over six tracks, addressing

News & Events

Two steps ahead towards sustainable public housing in Singapore As the public housing authority

that houses over 80% of Singapore’s

population, HDB has a key role to play

in supporting Singapore’s commitment

to sustainable development. Recently,

HDB made further progress with two key

initiatives:

a) Procurement of 1MWp solar

photovoltaic (PV) panels worth about

S$ 2.3 million from Renewable Energy

Corporation (REC). Th e solar panels will

be installed at six HDB precincts covering

about 3,000 residential units.

b) Collaboration with Camp Dresser &

McKee (CDM) to develop a modelling

tool to quantify and formulate a set

of key performance indicators (KPIs)

on sustainable environment targets in

developing Punggol as an Eco-Town

for the tropics. Th is will enable a more

eff ective design for sustainability, and

support HDB’s planning eff orts to

enhance resource effi ciency and liveability

within Punggol Eco-Town.

Th e announcement of the two

initiatives marked a key milestone for

HDB as it progresses towards creating

a more eco-friendly and sustainable

environment for public housing.

Mr Tay Kim Poh, CEO, HDB, said,

‘As the largest developer in Singapore,

HDB can play a leading role in supporting

Singapore’s eff orts towards sustainable

development. We see a lot of potential

in developing clean, renewable energy,

and particularly solar energy, given our

extensive coverage of HDB blocks all over

Singapore. We also see a lot of potential in

Punggol, our youngest town, and we aim

to further our eff orts in developing it as

Singapore’s fi rst Eco-Town. Hence, we are

excited about our partnership with REC

and CDM. Th ese initiatives will support

our eff orts to providing the best possible

homes and living environment for our

residents’.

Procurement of solar PV panels

Th e procurement of solar PV panels is

part of HDB’s Solar Capability Building

Programme for Public Housing, a wide-

scale test-bedding project which is funded

by the Inter-Ministerial Committee for

Sustainable Development (IMCSD).

Th e Solar Capability Building Programme for Public HousingTh e procurement from REC of solar

photovoltaic (PV) panels is the largest

single solar panel procurement in

Singapore to-date. Th ey will be installed

in precincts in Jurong, Aljunied, Telok

Blangah, Bishan, Ang Mo Kio, and Jalan

Besar, commencing in the 4th quarter of

2010. A total of about 3,000 residential

units will benefi t from this procurement.

Th is is part of HDB’s Solar Capability

Building Programme which aims to

achieve the following:

a) Build up expertise in solar energy

generation

b) Achieve profi ciency in design and

installation

c) Achieve cost-eff ectiveness

d) Enhance maintainability

REC is among the world’s largest

producers of polysilicon and wafers

for solar applications, and a rapidly

growing manufacturer of solar cells and

modules. REC is also engaged in project

development activities in selected PV

segments. Founded in Norway, REC is an

international solar company, employing

more than 3,000 people worldwide.

REC will provide the PV panels which

it produces locally. HDB carried out its

fi rst solar photovoltaic (PV) installation at

the Serangoon and Wellington precincts

in 2008, under a trial programme. Th e

capacity generated for each block was 10

kWp, with energy generation of 900 kWh

per month per block. Of this, about 600

kWh is consumed by the common services,

and 300 kWh is exported to the grid. Th is

translates into a 10% reduction in the

common area energy consumption.

Developing Punggol as an Eco-Town

HDB is reinforcing its commitment to

sustainable development in its public

housing estates. One of the initiatives that

it has taken in this area, is the fi rst non-

commercial collaboration with CDM to

develop a modelling tool to quantify and

formulate a set of KPIs, particularly in the

areas of:

Water reduction•

Energy reduction•

Waste reduction•

Ambient air temperature•

Provision of town greenery•

Alternative transportation utilisation •

As Singapore’s youngest town,

Punggol is equipped with green spaces

for spatial relief and community use,

and the necessary elements and facilities

to embrace sustainable living. CDM’s

Neyasdurai Centre in Singapore will help

to develop the Urban Systems Model to

support planning and design decisions.

Th e results from the collaboration will

translate into HDB’s planning and

sustainability design processes for the

development of Punggol as Singapore’s

fi rst Eco-Town.

CDM has a 36-year history in

Singapore, and has been involved in many

local water supply, waste water, drainage,

and solid waste projects. Th is collaboration

is scheduled for the period 12 July 2010

to end-December 2010. Depending on

the fi ndings, the collaboration may be

extended to 31 March 2011.
