INTRODUCTION The new Abu Dhabi Accountability headquarters will be located on a site that offers views of downtown to the south and the surrounding governmental and business district in addition to the limited opportunity of the site, the building restrictions, regional environmental conditions and response to traditional presents are the primary factors informing the design.

The headquarters building is composed of two main building masses the first mass is oriented perpendicular to the main road and obtaining the ideal orientation (East‐West) while the other mass is oriented parallel to the first one and forming a big scaled gate to the project.

The court yard at the North is derived from the traditional Islamic and gulf type, provides a shaded and protected center to the complex from here the view expands towards the external.

While maximizing views, the exterior facades are also designed to respond to climatic conditions. The Western, Southern and Eastern exposures incorporate both horizontal screens and deep ribbon windows to reduce glare and heat gain. Transoms above the screens have tinted glazing for additional solar protection. The response to the solar condition, together with variation in curtain wall treatment add a layer of detail and scale to the compact building mass. Metal structures shade the roof and provide a support to the photo voltage panels that will help using the facades.


STE ANALYSIS As per Abu Dhabi plan 2030

The Abu Dhabi Accountability site location is planned to accommodate national and institutional use and the maximum height allowed in this area is G+9 (40m) due to Al bateen airport being nearby.

Al Khaleej Alarabi and Sh. Saeed Al Maktom Roads are the main high ways leading to the area.

The site is located in the middle of the business district where some important and governmental buildings are surrounding the site.

Al the required facilities and services for the project are available around the site.

ENVIRONMENTAL ANALYSIS

OPTIMUM BUILDING ORIENTATION

Using Ecotect Environmental Design Software The Optimum Orientation For The Buildings In Abu Dhabi Has Been Calculated To Be 97.5o From North.

We have oriented the office mass to a close angle that is parallel to the plot boundary to achieve the maximum utilization of the land.


SITE ORIENTATION / WIND STUDY

Overlaying the climatic data onto the site shows the seasonal sun path as well as prevailing wind directions.

The high sun angles in summer can be efficiently blocked by horizontal shading devices, however lower sun angles at the east/west facades have to be mitigated with deeper shades.

The alternating wind direction is beneficial in designing the openings the favorable cool wind in summer, while blocking it in winter.

Simulating the movement of prevailing wind around the building’s mass, the court yard and the gate void will be utilizing designing natural ventilation strategies, to cool the building during appropriate summer months hence reducing the requirement for mechanical ventilation.


SOLAR SHADING

According to the studies done on the Building’s mass, Locations receiving the highest solar heat gain where identified and accordingly shading devices where introduced to block solar rays during the peak hours of summer,


SUN PATH STUDY


CONCEPT DESIGN Because of the function of the project as an important authority one of few that handles the monitoring of the accountability of other governmental authority and departments of Abu Dhabi, the transparency, clarity and this transparency was reflected in the overall design of this project

Using strong straight lines, curtain walls and white cladded walls that reflect the transparency that the function of the authority acts upon.

Culture

This building is considered as a new landmark which expresses the culture of UAE in general; The concept of this project come to emphasize on the future and to record this moment of change through the relationship between the old and the new, through the relationship between the traditional culture and the new emerging culture through the relationship between the past and the emerging future of Abu Dhabi.

The project is intended to be integrated within the local culture of UAE. Studying the different elements of the Libyan culture, the project has been inspired by the following elements:


GATE

As a symbol of traditional architecture, UAE is considered as an organic city at the heart of the desert, which has been developed through the years by its residents reflecting the unique gulf culture and reacting to the external environment of the place.

The traditional Gate is one of the features that تميز the Arabic Culture in general and Gulf style in particular. It has been used for the City Gates and palaces and even traditional houses and mosques.

Gypsum ART

This form of art, the “GRC” has been known in the Gulf culture since the times of the االسالمية فتوحال With its sophisticated details and natural colors, Gypsum pattern is considered as a symbol of the gulf art


CULTURAL ASPECTS After a thorough study of the UAE culture; we chose these four illustrated patterns to be used in the building somehow whereas it is either used inside the building, the building gate frame, the large glass box located in the middle of the gate or on the boundary wall around the building.


Design Challenges: One of the main challenges is the future surrounding buildings witch will negatively affect the present of the building along the main street and in case they are built on the edge of the plot will hide most of the ADAA Headquarters.

We have tried all possible shape configurations within the plot to exam the vision impact on the building in the future we found out that To Form an Iconic monumental frame for the building which has a strong present on the area will avoid 0000000 of the building within the site however parts of it are hidden behind the new neighbors.

SETBACKS

We have recommended creating a courtyard facing the North versus having equal wider setbacks in both sides allow having internal shaded area for social gathering for the building users as well as welcoming the important visitor for the Authority.

And Further To The Setbacks Defined By The Site Boundaries. It Was Seen To Introduce a Setback Spacing Between The building and the adjacent Buildings At three sides. This Insures That The l Buildings Receive Sufficient Natural Sunlight, Natural Ventilation And Sky Access.

Accordingly a Distance of 4 m was allowed as a setback.

GRID OPTIONS

To Achieve the Highest Structural and Geometrical Efficiency, a Study has been Done to Optimize the Column Locations, Parking Grids And Aisles. This Insures the Optimum Organization of The Floor Plans Without Impacting On The Flexibility.


Views:

Studying The Site’s Context Reveals Recommended Views Towards the main Road to the west and towards the sport city and Sh zayed grand mosque from the upper floors with Less Recommendable Views towards neighbor sides.

The courtyard space became a considerable internal view which maximize the opportunity of good views for most of the office spaces.

The two main masses are positioned in a way not to obstruct the view for each other and open the view to outside towards the main road.

The last floor where the chairman office located enjoys the best views as two side views towards the main road and to the internal courtyard is obtained.

DESIGN SKETCHES The initial thought was to create a statement that presents the governmental Importance. Examining different type of shapes that give this effect meanwhile have the best site utilization, constructability and efficient and confortable office spaces.


BUILDING CODE Occupancy Load:

As per international Building Code which Abu Dhabi is implementing; 9.3 square meters are dedicated for each person in business use buildings which means that the maximum capacity of the building could reach up to 1236 occupants.

However as per the design brief; the building will accommodate 160 occupants while in future with some modifications in internal partitions and furniture the capacity of the building will reach to its maximum.

Sanitary:

As per International plumbing Code table: 403.1 two groups of male and female toilets should be provided contains 3 toilets and 2 wash basins for each.

Handicap toilets for M/F have been provided as per the accessibility chapter in international building Code.

Parking:

As per (Car Parking Design Standard) issued be Department of transportation of Abu Dhabi a rate of 2.4 cars per 100 square meters of Gross floor area should be provided.

Having 3 underground levels for Car parking we obtained 183 parking slots with a shortage of 105 parking slots.

The shortage could be covered be having a forth basement as a solution.

Other option is to use Automated parking Garage that will provide extra parking and could reduce the basement depth.

1 GENERAL This volume summarizes the construction methodology for the Abu Dhabi Accountability Authority Head Quarters. The parameters have been established as being the most appropriate for the Project, where the proposed structural system accommodates the building functions, its architectural design and the building service requirements.

2 MATERIALS

The choice of construction material in Abu Dhabi is affected by many factors specific to the region. The following list identifies the most significant of these:

• High temperatures, which can exceed 45 Celsius at peak times. • Airborne salt contamination due to the coastal location and high humilities. • Large temperature ranges from day and night and seasonally, these can have significant

effect on the thermal movements of material such as concrete and hence the requirement for regular spaced movement joints.

• High evaporation rates due to the high temperatures; this can cause in‐situ concrete to dry quickly causing damaging thermal shrinkage.

• Availability of local sources of raw materials

The above mentioned factors are considered in the selection of construction material along the structural advantages and disadvantages of different options, where in all cases great care must be taken to ensure the structural integrity.

2.1 Reinforced Concrete

Reinforced concrete is the most common indigenous and locally available structural construction material. Concrete’s versatility, durability and economy have made it the world’s most used construction material. It is used in buildings, high‐rise, dams, homes, floors and numerous other applications. Concrete is strong in compression, but weak in tension, thus adding reinforcement increases the strength in tension. In addition, the failure strain of concrete in tension is so low that the reinforcement has to hold the cracked sections together.

For a strong, ductile and durable construction the reinforcement shall have the following properties:

• High strength • High tensile strain • Good bond to the concrete • Thermal compatibility • Durability in the concrete environment

Reinforced concrete can encompass many types of structures and components, including slabs, walls, beams, columns, foundations, frames and more. Much of the focus on reinforcing concrete is placed on floor systems. Designing and implementing the most efficient floor system is key to creating optimal building structures. Small changes in the design of a floor system can have significant impact on material costs, construction schedule, and ultimate strength, operating costs, occupancy levels and end use of a building.

Figure 2.1 Reinforced Concrete Constructions.

S T R U C T U R E

The advantages of using reinforced concrete are:

• Local contractors and their tradesmen are experienced in reinforced concrete construction;

• The reinforced concrete trade is well established in the Emirates; • The building materials used are available locally; • Total flexibility in space planning; • Better resistance to environment attack from salt‐laden water; • Concrete has increased resistance to explosion and/or impact; • Concrete resists very high temperatures from fire for a long time without loss of

structural integrity; • Concrete inherent mass and strength provides resistance to lateral forces; • Concrete seeks the form – any shape can be achieved; • Concrete has flexibility to accommodate design changes later in the progress; • The inherent mass of concrete provides benefits in terms of acoustics and

vibration criteria of the building.

High yield deformed steel bars with a characteristic strength not less than 460 MPa proposed to be used. Reinforcement used for the concrete piles can be epoxy coated and/or special admixtures to the concrete can be used to control corrosion.

Fig. 2.2 Epoxy Coated Rebar Fig. 2.3 High Yield Rebar

2.2 Precast – Prestressed Concrete

Precast Concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site‐specific forms and cured on site. Precast stone is distinguished from precast concrete by using a fine aggregate in the mixture so the final product approaches the appearance of naturally occurring rock or stone. By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. Utilizing a Precast Concrete system offers many potential advantages over site casting of concrete. The production process for Precast Concrete is performed on ground level which helps with safety throughout a project. There is a greater control of the quality of materials and workmanship in a precast plant rather than on a construction site. Financially, the forms used in a precast plant may be reused hundreds to thousands of times before they have to be replaced which allow cost of formwork per unit to be lower than for site‐cast production. There are many different types of precast concrete forming systems for architectural applications, differing in size, function and cost. Precast architectural panels are also used to clad all or part of a building facade free‐standing walls used for landscaping, soundproofing and security walls and some can be Prestressed concrete structural elements. Prestressed concrete is a technique that greatly increases loadbearing strength of concrete beams, slabs and walls. The reinforcing steel in the bottom part of the beam, which will be subjected to tensile forces when in service, is placed in tension prior to the concrete being poured around it. Once the concrete has hardened, the tension on the reinforcing steel is released, placing a built in compressive force on the concrete. When loads are applied, the reinforcing steel takes on more stress and the compressive force in the concrete is reduced, but does not become a tensile force. Since the concrete is always under compression, it is less subject to cracking and failure.

Figure 2.4 Precast construction

3 DURABILITY

Concrete structures shall be designed to resist attack from the following environmental conditions:

1. Sulphates and chlorides in the subsoil. 2. Sulphates and chlorides in ground water. 3. Wind‐blown salts including aerosols. 4. The aggressive climate, including marine conditions. 5. Availability of suitable water for mixing and curing concrete. 6. Possible contamination by Sulphates and chlorides in aggregates.

4 DESIGN PHILOSOPHY

Generally, the design philosophy for the structure is as follows:

• Gravity loads will be transferred from the floor plates to vertical elements like columns and walls, lateral loads will be transferred through floor diaphragm to the lateral loads resisting

system of shear walls and / or rigid columns. Scheme framing diagrams is shown in figure 2.5.

• Efficient transfer of loads from floors to foundation will be adopted consistent with the

architectural requirements.

• Maximization of materials and content of local origin will be a priority and will be taken into account in the design decision process relating to the structural media and form.

• Incorporation of local construction practices and methods and use of local materials, which

may give rise to savings, will be considered during the design process.

• High strength materials for concrete, reinforcing steel and structural steel will be used where possible within the constraints set by serviceability requirements. This results in greater efficiency of construction materials and a lower cost of construction.

4.1 FOUNDATIONS

Abu Dhabi is situated towards the eastern extremity of the geologically stable Arabian Plate and is separated from the unstable Iranian Fold Belt to the north by the Arabian Gulf. It is believed that a tilting of the entire Arabian Plate occurred during the early Permian period, resulting in uplift in southern Yemen and depression to the north east. Tectonic movement’s peripheral to folding of the Iranian Zagros Range during the Pilo‐Pleistocene epoch probably contributed to the formation of both the Arabian Gulf depression and the mountainous regions in the north east of the UAE and Oman. Of particular interest geologically and geotechnically is the presence of weakly cemented calcareous deposits, deposits of evaporates, mainly gypsum and potential cavities/vast features.

The foundation design will be based on the subsurface soil investigation interpretive report and recommendations of the geotechnical specialist. Foundation type will be further discussed during the Schematic Design phase upon soil investigation completion. A combination of high performance concrete and an external membrane system to achieve the necessary water proofing and durability will be used for the foundation. The use of a high performance concrete in the foundations and basement external envelope is essential to the design. The concrete mix needs to be dense and impermeable, to prevent the ingress of water, chlorides and sulphates into the concrete matrix to achieve the required level of durability. The concrete must also display low shrinkage and coefficient of expansion characteristics to achieve the joint‐less construction required by the design.

4.2 SUPER STRUCTURE SYSTEM DESCRIPTION

Abu Dhabi Accountability Authority Head Quarter comprises of 7 story plus two basement level structure with span requirements of approx. maximum of 9 meters and with approximate height clearance of 4 meters.

Building’s lateral stability is provided by the conrete shear walls. Slabs are acting as diaphragms in order to transfer horizontal forces to the vertical bracing elements (columns and shear walls). The diaphragm action is obtained by a system capable of transferring the horizontal forces by arching or bending. The system is capable to obtain all forces due to in‐plan action like bending, shear and tension and shall be continuous both in longitudinal and transverse direction. The utilization of Precast Concrete Hollow Core Slab framing system is introduced for this building which has an approximate uniform spanning of 8.5 meters. 265mm thick hollow core slab with 65mm cast in situ concrete topping with minimum reinforcement area is

capable to support the transfer loading forces as composite section to the transversal nipped beams resting on the vertical structural elements “columns and walls”. See figure 2.6 for Hollow Core Slab photo. Hollow core slab is supported on beams, refer to figure 2.7 for the typical detail of hollow core slab resting on beams. Beams are supported by 800x800mm columns that are placed typically in a grid system. In addition to the reinforced concrete columns, 300mm thick reinforced concrete walls are introduced as lateral forces resisting system. Refer to figure 2.8 for the Proposed Building Frame and figure 2.9 for the proposed Typical Framing Layout.

4.3 ADVANTAGES OF THE PROPOSED SYSTEM The proposed system presented part traditional construction and part Off‐site construction. Advantages of traditional construction are discussed on section 2.1. This section will focused on the Off‐site Construction advantages, as follows:

• Speed of design (typically 30‐60% quicker design time) • Flexibility of design (ability to “plug & play”) • Concurrent production, whist enabling works are under way • Minimized site disruption, due to far less time on site compared to traditional

construction methods • Improved quality: controlled conditions not weather dependant • Flexibility, through future expansion & relocation • Far greater control over MEP, installation and design most of which is pre‐commissioned

under factory controlled conditions • Construction schedule, reduced construction time by up to 50% • Risk, increased predictability of project outcomes in terms of quality, cost and time • Quality, factory production methodology allows for the improvement of building

quantity • Procurement, increased ability for collaboration and single‐point of responsibility • Factory Time Efficiency, methods of production reduce construction tast time • Disturbance minimizes, disruptions to adjacent buildings and occupants and increase

cleanliness of building process • Technology, greater ability to manufacture components with high degree of technical

complexibility • Site, eliminates various site constraints such as staging, weather, transportation, etc. • Security, factory environment improves conditions for constructioin workers • Sustainability & Waste, improved project sustainability and viability of LEED ESTIMADA

rating • Relocability, possibility to move structure to new location • Economies of Scale, typical benefits of economy of scale are amplified for large projects

For Abu Dhabi Accountability Head Quarters two types of superstructure system can be adapted,

1. Hollow core slabs with Reinforced Concrete Framing. This system is a Hybrid Style Construction that comprises of traditional beams,columns and shear walls cast in‐situ construction and precast slabs construction.

Hollow core slabs are introduced for the floor system. Pre‐cast pre‐stressed concrete elements with continuous voids to reduce self‐weight and achieve structural efficiency are very popular and economic across a wide range of spans and loadings. The slabs are part of a full frame system and are capable to provide rigid floor diagphram in precast construction. Figure 2.10 Hollow Core Slab supported on Concrete Beams.

The continuous slab voids can be used as heating or cooling ducts and as raceways for electrical wiring while reducing sound transmission and vibrations between floors. Hollow Core floor planks are usually designed as simple, one‐way‐spanning slabs. Floors are often subject to non‐uniform loads such as line loads, concentrated loads or loads at openings.

2. Precast slabs, beams, columns and cast in‐situ shear walls. This system is a Precast Construction throughout with cast in‐situ shear walls only. It is best recommended to use reinforced concrete for shear walls to resist lateral forces applied to the building.

Precast Construction is one of the most versatile and sustainable building materials available for today's fast‐paced, environmentally conscious construction. Combining the strength and durability of concrete with the flexibility and aesthetics of precast elements, it is considered on the most economical and attractive construction solution available. As discussed, several advantages using precast or Off‐site construction.

8.5.6 Capacitor Banks

8.5.6.1 Reactive Power Compensation

Electrical networks which include major inductive loads (e.g. motors) shall operate under poor overall lagging power factor conditions. Also, in case these inductive loads are constantly being switched on and off (e.g. HVAC equipment motors), the power factor of the overall system shall change with every switching operation. A poor power factor is a major (and avoidable) cost factor. There are basically three methods which are commonly used to compensate for the inductive power drawn by a load or an electrical installation, and thereby improve its power factor.

Option‐1:

Individual Compensation

In the case of individual compensation, the capacitors are connected directly to the terminals of the individual loads and are switched in and out of circuit by the same common switching device. The chillers shall be provided with its own PFC capacitors to improve the power factor to 0.95.

Option‐2:

Group Compensation

In this case, the power factor correction equipment provides a fixed value compensation for a number of motors or e.g. fluorescent lamps which are switched as a group by means of a common contactor or circuit – breaker.

Option‐3:

Centralized Compensation

In most cases power factor correction units, which automatically switch power capacitors into or from the load circuit, are used for centralized power factor correction. They are usually directly associated with, and installed centrally at, a particular switchboard, distribution board or incoming supply.


8.5.6.2 Selection of Type of Compensation

The most suitable type of compensation is arrived at based on a number of technical and economical aspects. Generally, central power factor correction units have a higher price per installed kVAR. As a guideline, it has been found that the cost of the two methods is comparable for a diversity factor (or load factor) as high as 0.7 to 0.8. If the diversity factor is lower, the centralized method of compensation becomes more attractive.

In general, the system proposed for the project is centralized compensation which also complies with ADDC requirements. The chillers shall have its own PFC capacitors as part of the soft starter.

Capacitor banks shall be provided to improve the system power factor to greater than 0.90 lagging and shall be installed across the MDB.

8.12 Lightning Protection System

8.12.1 Effects of Lightning Strike

8.12.1.1 Electrical Effects As the current is discharged through the resistance of the earth electrode of the lightning

protection system, it produces a resistive voltage drop which may momentarily raise the potential of the protection system to high value relative to true earth. It may also produce around the earth electrode a high potential gradient dangerous to people and animals.

8.12.1.2 Side Flashing The point of strike on the protection system may be raised to a high potential with respect to

adjacent metal. There is therefore a risk of flashover from the protection system to any other metal on or in the structure. If such flashover occurs, part of the lightning current is discharged through internal installations, such as pipes and wiring, and so this flashover constitutes a risk to the occupants and fabric of the structure.

8.12.1.3 Thermal Effects For the purposes of lightning protection, the thermal effect of a lightning discharge is

confined to the temperature rise of the conductor through which the current passes. Although the current is high, its duration is short and the thermal effect on the protection system is usually negligible.

In general, the cross-sectional area of a lightning conductor is chosen primarily to satisfy the

requirements of mechanical strength, which means that it is large enough to keep the rise in temperature to 1°C.

8.12.1.4 Mechanical Effects

Where a high current is discharged along parallel conductors in close proximity or along a single conductor with sharp bends, considerable mechanical forces are produced.

Similarly, with a side-flash inside the building, the shock wave can result in damage to the

building fabric.

8.12.1.5 Function of a Lightning Conductor

A lightning conductor is incapable of discharging a thunder cloud without a lighting flash. Its function is to divert to itself a lightning discharge which might otherwise strike a vulnerable part of the structure to be protected and to convey the current safely to earth. The range over which a lightning conductor can attract a lightning flash is not constant but it is now believed to be a function of the severity of the discharge.

The range of attraction is therefore a statistical quantity.

On the other hand, the range of attraction is little affected by the configuration of the conductor, so that vertical and horizontal arrangements are equivalent. The use of pointed air terminations or vertical finals are therefore not regarded as essential, except where dictated by practical considerations.

8.12.1.6 Need for Protection

The following situations are to be considered while ascertaining the need for protection:

a) Where large numbers of people congregate. b) Where essential public services are concerned. c) Where the area is one in which lightning is prevalent. d) Where there are very tall or isolated structures. e) Where there are structures of historic or cultural importance. f) Where there are structures containing explosive or flammable contents.

1. Heat recovery units 2. Water supply pumps with VFD 3. Glass thermal properties and external walls construction details 4. Building management system 5. Thermal control and zoning 6. Power factor correction 7. Lighting control system 8. Energy saving lamps 9. Electronic ballasts

15.3 Heat Recovery Units The central extract system risers from toilets and general areas shall be discharging cold/hot air with different temperature related to every season.

Heat recovery sections comprising thermal wheel shall be added to the FAHUs to exchange cooling/heating from the extract air duct risers, which leads to increasing/reducing the temperature on the heating/cooling coil of FAHU.

A significant amount of cooling/heating can be retrieved by this unit, thereby reducing the cooling/heating load on chillers /boilers and electrical power consumptions accordingly.

15.4 Water Supply Pumps with VFD Main booster water pumps will be equipped with negotiable speed drives and shall be employed to supply water to the entire facility.

These pumps will supply varying amount of water proportional to the demand dictated by the project. Therefore at a time of low demand these pumps shall not work on full capacity and thus reduce electrical consumption.

15.5 Glass thermal properties and external walls construction details We recommend the use of high performance double glazing for all floors and thermal insulated external walls for the entire building. This will help in reducing the cooling/heating load as well as in reduction of noise transmission.

15.6 Building Management System (BMS) Introducing BMS for the building will result in significant energy saving by switching off all unnecessary loads

15.7 Thermal Control and Zoning The design will allow individual users to control air supply rates, air temperatures and humidity (for some specific areas) which will allow a reduction in load requirement during partial/no‐occupancy hours.

15.8 Power Factor Correction

Utilization of power factor correction system will result in a huge reduction of the reactive power as described hereunder:

Total connected load = (X) KW

S = Apparent Power = (X) KW

P = Active Power = S cos Ø

Q = Reactive Power = S sin Ø

COS Ø1 = Uncorrected power factor = 0.8

COS Ø2 = Corrected power factor = 0.93

Estimated reactive power saving = 7.5 %

15.9 Lighting Control System

The most intelligent lighting control system will be utilized and will be based on occupancy sensors, timers and photo cells. By utilizing this system all unnecessary luminaires will be switched off and accordingly a saving of 20% in energy consumption for lighting will be achieved.

INTRODUCTION A‐Introduction:

Environmental impact of Buildings

According to the UAE Minister of Public Work the baseline benchmark referring at energy: 300kWh /sqm annually and water: 500 liter per person per day. The U.S. Department of Energy data book – October 2009, commercial building in the United States indirectly contribute 18%, or 6 billion metric tons, of the nation’s dioxide (Co2) emission through the consumption of energy, and consume 35.8% of all electricity generated in the United State. More than 50% of this electricity is derived from carbon –intense energy sources, such as coal and petroleum. Built a green building is not only mandatory by law but is an opportunity to positively impact the environment and meet the requirement of the RFP. The Owner is receptive to implementing measures that will positively impact them and will appreciate that you have educated them about green options

Commitment to sustainability

The process of integrating Estidama principal into property management is not always a linear journey. There are multiple entry point, and most owners and operators will have already start on many of the task outlined propose in this proposal. Regarding of where one begins, there are several consistent element to achieve success, beginning with making a commitment.

Changing the manner in which commercial property is operated does not need to be complex, but it has to start with commitment from stakeholders. Building Managers and owners must be committed to adopting sustainable practices and incorporating sustainability into their decision making. Many measures and policy changes can help transform a building’s operation, but without a commitment, these actions will not necessarily deliver the intended results. Greening a new building does not always demand a significant capital investment, but it does require the desire to find solution and willingness to measure efforts.

Greening Process.

There are five areas in which building can be greened:

‐ Energy‐saving ‐ Potable water reduction and water conserving initiatives ‐ Health ‐ Safety ‐ Indoor and outdoor environmental quality

In order successfully pursue Estidama Pearl Rating System PBRS certification, proper preparation and visioning is critical before commencing. Without buy‐in from of the involved parties, the creation of committed team, and proper financial planning, projects run the risk of falling short on their certification goals. Estidama Vision Abu Dhabi's Plan 2030 establishes a clear vision for sustainability as the foundation of any new development occurring in the Emirate and capital city of Abu Dhabi. This commitment is a reflection of the values and ideals of our nation. The tenets

of sustainable living in the Middle East are the guiding force behind Estidama. More than just a sustainability program, Estidama is the symbol of an inspired vision for governance and community development. The ESTIDAMA certification system is a flexible framework that allows project teams to decide which sustainable strategies to pursue based on the specifics of a particular project. ESTIDAMA requires all projects to meet certain prerequisites, and project teams choose which optional credits to pursue for additional points toward certification.

Method Statement for the Estidama Services RW Armstrong Sustainability Team will collect the data and develop strategy for sustainable, green building technologies and energy efficiency for ADAA headquarters. To provide the best sustainability intent in the cost effective way to achieve tree pearl required from the client. RW Armstrong as Sustainability Team will refer as guideline on the ESTIDAMA Building Perl Rating System (PBRD ver. 1) developed by Abu Dhabi Urban Planning Council (UPC).

After the data collection RW Armstrong Sustainability Team will consolidate the “Estidama strategy” and necessary report necessaries for the UPC preliminary design review for the New Headquarter for Abu Dhabi Accountability Authority (ADAA) Project.

The final result of the consolidation we will a list of achievable credit/recommendation to achieve the main target of the project.

The Consultant will must follow the ESTIDAMA Review Process of Abu Dhabi UPC and the framework. The Design team will be assisted in all the stage of the project to comply with: credit intent, credit requirement, and calculation methodology and should use all the reference included in the Rating System Sheet during the design stage. RW Armstrong Sustainability Team will provide the required document that will show the effective compliance with the credit requirement split in the 7 project stage.

Stage 1 – Concept design Stage 2 Schematic Design Stage 3 – Design Development Stage 4 – Tender/Construction Document Stage 5 – Tender services Stage 6 – Construction Supervision Stage 7 – Project Close out RW Armstrong Sustainability Team will assist the design team in all the project stage, in coordination and the implementation of an Integrated Design Process. The integrated project delivery will be maintain with interact keck‐off meeting, a program workshop and other workshop spitted in all the project stage. Regular weekly and bi‐weekly meeting


RW Armstrong Sustainability Team will assist the Design Team to develop a holistic concerted concept in order to considerably improve the energy efficiency, sustainability and living quality of the building. RW Armstrong Sustainability Team will develop in the Estidama Concept Report, the best strategy in order to provide a cooling building strategy. The Sustainability Team will support the Landscape architect to create an interconnected network of open spaces, differing in size, character and purpose to support a variety of human activities and natural systems, in order to increase the permeability of the building and create and improve the active urban environments of the area with less urban heat reduction. All the consideration will demonstrate and commented with the utilization of tools (Autodesk Ecotect Analysis and SunPath), and develop inside of the Sustainability Concept Report:

‐ Commented Bio‐Climatic Analysis: ‐ Climatic Analysis (latitude, climatic data, solar radiation, local specific condition of prevalent winds) ‐ Natural input (orientation and morphology) ‐ Dynamic shadows Analysis ‐ Orientation and shadow analysis ‐ Outdoor Thermal Comfort Strategy ‐ Thermal analysis Study ‐ Passive housing strategy and calculation ‐ Cool Building passive strategy ‐ PBRS Energy calculation ‐ PBRS Water Calculation ‐ PBRS Waste Calculation ‐ Selection of plant strategy for landscape or xeriscaping

RW Armstrong Sustainability Team will assist the MEP Team to develop and optimize and integrate a comprehensive water strategy during the early stage of design with the goal of minimizing the overall water consumption and establishing a project water balance. The Sustainability Team will also recommend the MEP Design Team to reduce the potable water use in exterior water features by minimizing evaporative loss and through the use of recycled water for achieve the target of 20% base on the ESTIDAMA PBRS water Calculator ver. 1.2. Will also help the MEP Design Team to recued the energy consumption and carbon emission associated with lighting and reduce peak electricity demand and increase efficiency in order to achieve the target of 45% of reduction base on ASHRAE 90.1.2007

Estidama Strategy for ADAA This ESTIDAMA approach to integrate the various design elements, in order to reach a Sustainable Green Building Design included in the Client’s vision for the Abu Dhabi Accountability Authority (ADAA) Project

The client vision related to the sustainability is to achieve Estidama 3 pearl according to the PBRS that mean achieve all mandatory credits plus 85 credit point The main design considering the following criteria:

‐ Reduce impact on the environment by proper selection of construction materials ‐ Design energy efficient building ‐ Create and maintain a healthy and natural environment ‐ Provide the residents‐users controls on their comfort ‐ Enhance natural lighting (day lighting) ‐ Waste Management and recycling. ‐ Integration to surrounding urban networks The building will be designed in a way to operate and serve to achieve luxury level of 5 star hotel the expected not ordinary comfort in compare to in similar projects, while minimizing energy and resources usage. Various systems and components

are to be coordinated to provide the maximum energy usage efficiency under the buildings’ operating and budgetary constraints alongside with provision of thermal comfort and enhanced and monitored indoor air quality.

In addition, the sustainable design will also cover the construction and the operating phases of the Project. In the Construction phase, controlling construction waste and emissions, using environmental friendly and renewable materials, and minimizing construction and equipping induced environmental effects. During the Operational phase, the aim is to mitigate the Project’s impacts on its surroundings, by reducing both its energy usage and waste production.

ESTIDAMA‐based Sustainable Design Basic Concepts For the purpose of the Abu Dhabi Accountability Authority (ADAA) Project, a set of basic design concepts are defined earlier in this phase. They constitute the Sustainability Basis of Design of the ADAA project, addressing architectural and structural aspects, as well as the HVAC and electrical utilities and services.

These basic design concepts fall under seven major categories:

• IDP ‐ Integration Development Process • NS ‐ Natural System • LBo ‐ Livable Building: Outdoor • LBi ‐ Livable Building: Indoors • PW ‐ Precious Water • RE ‐Resourceful Energy • SM‐ Stewarding Materials

It is worth defining in this ESTIDAMA Proposal report these basic design concepts as follows:

IDP – Integration Development Process An essential part of the strategy for achieving Estidama is to fundamentally change the way we approach design, construction. The Integration Development process calls for cross‐disciplinary teamwork and builds upon sound thinking, delivery quality and environmental management through the life of the project. This approach requires an integrated design approach from very early on in the design a clear vision and sustainability targets and implementation strategy.

The strategy to achieve the requirement past by:


The forecast Estidama achievable credit related to this Pearls Building Rating System section will include:

1. Develop and maintain an Life Cycle Cost (LCC) analysis from the concept design by a qualified professional, to evaluate and compare various design option throughout the design stage in option appraisals

2. Develop an Guest Worker Accommodation Plan with the contractor to promote fair labor practices in building construction

3. Develop with the contractor the Construction Environmental Management Plan (CEMP)

NS – Natural System Fundamental of the Abu Dhabi Plan 2030 is the need to foster careful, sensitive growth that will conserve, preserve, and restore the region’s critical natural environments and habitats. Plan 2030 concept is to create a green gradient that design an adequate level of conservation, prevention and restoration and propone an open space framework, a system of formal and informal spaces to implementing leading to healthier ecosystem, habitat and ultimately communities.

The intent of this credit section is intended to encourage natural resource management and sustainable land use trough:


1. Enhance the ecological value of the site by planting native or adoptive species

LBo – Livable Building: Outdoors In order to be considered truly sustainable, new development must go beyond the environment to address the other three pillars of Estidama: Social, Cultural and Economic. This requires consideration of issues such as increased mobility and access to community facilities and connectivity and comfort of the public realm to encourage increased pedestrian activity. Our ultimate goal is to create a cohesive, contemporary and sustainable urban fabric for this new city and prosper as an attractive, livable place that preserves the emirate’s unique culture and environment.


1. Increase outdoor thermal comfort during transition months and reduce thermal discomfort during summer months in public spaces and walkways

2. Encourage active lifestyle by providing building occupants and users with recreational public open space 3. Encourage the reduction of night time light pollution and its associated impact on human and ecological health.

LBi – Livable Building: Indoors Further research suggests that Green Building with improved indoor environmental quality can reduce the number of work days lost to sick leave by approximately three day per person per annum. Similarly, an increase of almost 5% in productivity has been attributed to healthier indoor environments. In order to creating a ‘livable indoors’ the new development buildings that address the challenges of improving occupant health and wellbeing whilst fostering economic growth anticipate from productivity gains, staff redemption and reduced absenteeism.



1. Increase outdoor thermal comfort during transition months and reduce thermal discomfort during summer months in public spaces and walkways

2. Encourage active lifestyle by providing building occupants and users with recreational public open space 3. Encourage the reduction of night time light pollution and its associated impact on human and ecological health. 4. Promote the provision of building system that support the wellbeing and comfort of occupants by providing

sufficient outside air ventilation 5. Low emission material to encourage the desirability of their space in relation to improved occupant 6. Implement Hybrid‐construction method off‐site construction practice that promotes a high degree of indoor air

quality (IAQ) for construction workers and building occupants. 7. Provide adequate air quality within enclosed car parks. 8. Provide individual comfort control for the wellbeing productivity and thermal comfort of occupants. 9. Promote indoor visual comfort through the interior natural daylight and use of high frequency lighting solution 10. Provide building occupants with a visual connection to the outdoors 11. Provide acoustic conditions that area commensurate with the sensitivity and the privacy requirement of the

propose use.

PW – Precious Water Water conservation is a priority for Estidama, because Abu Dhabi has a limited annual rainfall, hot climate, and the significant embodied in potable water due to desalination. One of the most important challenges for the Emirate is to balance water supply and demand as efficiently as possible given that the per capita consumption of fresh water is among the highest in the world and new water supplies are expensive

The Precious Water section of the PBRS includes the building calculator that should be used throughout the entire design process. This will help the designer team to assess inputs and flows of water to and from the project with holistic perspective, and assist in identifying how and where reductions in the use of potable water may be made.


1. Improve of the reduction of 20% for the interior potable water consumption through the use of efficient fixture and appliances, and the use of recycled water.

2. Minimize landscape water demand through effective plant selection, irrigation strategies and promoting the use of recycled water

3. Reduce potable water use for exterior landscape excluding the any water feature from the project 4. Minimize peak storm water discharge and protect the storm water drainage system and receiving water bodies

from pollutant loading during and after storm events.

5. Minimize the storm water discharge and protect the storm water drainage system and receiving water bodies from pollutant loading during and after storm event.

RE – Resourceful Energy Through the Pearl Rating System, Estidama seeks to target energy conservation through technological transitions in the building sector. Techniques to conserve energy at the building design and construction stage can have significant impacts on reducing overall energy consumption during operation. The resourceful Energy section requires energy calculation and assessment process to be undertaken. This assessment will facilitate careful consideration of energy issues during the design of building, resulting in better informed decision making.


1. Determine the most effective solution to reducing a building’s cooling demand by incorporating passive design strategy as a priority awarded based on reduction in the annual external heat gain of the propose building compare with the baseline

2. Minimize the energy consumed by common building appliances 3. Promote project that specify and install energy efficient vertical movement and transportation system

SM – Stewarding Materials In a sustainable development, the materials chosen, and the process by which associated waste is disposed, should be viewed as a complete cycle, not two disconnected processes. Transportation of waste use large amount of fossil fuel and decaying landfill trash generates methane, a major greenhouse gas. The stewarding material section of the PBRS encourage the design team to consider this entire continuum – or ‘whole‐of‐life’ cycle when selecting and specifying material, with an overall objective to improve the social and environmental outcomes associated with their manufacture, transport, installation and disposal.



1. Promote selection of material that do not have long term negative impact on human health or pollute natural systems

2. Lengthen the useful life of building through design that is easily adaptable for other program uses. 3. Facilitate the future deconstruction and reuse of building and their structure and envelope components 4. Minimize waste associated with replacement of flooring system through the use of modular system 5. Encourage the use of timber sourced from legal and sustainable sources
