SUSTAINABILITY..WHAT IS THE

DRIVEN

FACTOR???


3/33

MAJOR FORCES TO CONSIDER

SUSTAINABILITY???

1. Sustainable development movement

2. Environmental Issues

Climate change increasing concentrations of human-

generated carbon dioxide, methane,

etc affect our future temperature regimes &

weather patterns.

Green house effect

3. Social interest (workers safety, occupiers safety,

etc)

4. Long term economic return (intangible value)


4/33

CLIMATE CHANGE

Global temperature increase 0.75C over thepast century

Rainfall patterns wet getting wetter, drygetting drier

Humidity increases over the last two or threedecades make extreme rainfall and flooding morelikely

Warming oceans e.g Atlantic, Pacific and

Indian oceans, not linked to natural variation Salinity increased evaporation is making the

Atlantic saltier in sub-tropical latitudes

Sea-ice summer Arctic se-ice is declining by600,000km2 per decade


5/33

GREEN HOUSE EFFECT

Natural process of the atmosphere letting in

some of energy we receive form the Sun (UV and

visible light) and stopping it being transmitted

back out into space (infrared radiation of heat).

Earth more warm

Nowadays, human has influence the balanced ofatmosphere, resulted on climate change


6/33

CAUSES OF GREENHOUSE EFFECT

Human activity is changing the amount of green

houses gasses in three major activities;

Burning fossil heating/cooling homes,

transporting, cooking food, travelling, treatingwater to make it drinkable

Deforestation causes 5.9 billion tones of CO2per year

Growing world population

need foods, producemore waste, use more natural resources


7/33

WORLD CRISIS DUE TO CLIMATE

CHANGE..

MIT Integrated Global System Model

To the population

Water & food live in water stress regions &

malnutrition is expected to increase inDeveloping country

Health threatened by heat-waves, floods,

storms

Environment flooding.. Ecosystems damaged by deforestation

Increased CO2 emissions


8/33

CONSTRUCTION IS ONE OF THE

MAIN CONTRIBUTOR OF

ENVIRONMENTAL ISSUES..THAT IS WHY, WE NEED TO

ADOPT SUSTAINABILITY IN OUR

INDUSTRY..


9/33

WHAT IS THE DEFINITIONS OF

SUSTAINABLE CONSTRUCTION??

Creating and operating a healthy built

environment based on resource efficiency and

ecological design..Charles J. Kibert

The balanced uses of resources on a global scale

including physical elements, human elements,and national political context.

Ronald Rovers


10/33

WHAT IS THE DEFINITIONS OF

SUSTAINABLE CONSTRUCTION??

The development which meets

the needs of present without compromising theability of future generation to meet

their own need

Bourdeau, 2000


11/33

THE HISTORY INMALAYSIA???

Has been applied in Malaysian Developed Plan

since 1970s.

Has been the buzzword since 1980s.

Logically sustainable and balance being themain focus to improveMalaysian economic (1991

2000).

Years by years, the Department of Environment,

in close cooperation with central agencies,government related agencies, institution experts,

and NGOs work together to develop plans to

make sure Sustainable Development can be

achieved by 21st century.


12/33

DEVELOPMENT BACKGROUND???

The book Malaysias Vision 2020 published in 1993defined national ambitions and future opportunities forresearchers and to consider long-term strategies to assistthe achievement of national goals. One of the basic visionsthat emerged is for the country to be ecologicallysustainable. This basic vision has become an impetus

toward sustainability agenda in the country. The issue ofsustainable development has emerged as one of the topissues in the Eight Malaysia Plan (20012005). Accordingto the plan, the government gave high priority to researchand development as one of their strategy for sustainabledevelopment (EightMalaysia Plan, 2001). Section 19 of the

plan was devoted to integrate environmental considerationinto development planning. During that period, concertedefforts were expected to intensify in order to improveenergy efficiency, forestry, waste and environmentalmanagement.


13/33

EXAMPLE OF THE DEVELOPMENT???

o At present, there are several sustainable

projects that are being or have been constructed

inMalaysia. One of the examples is project

Tanarimba at Janda Baik, Pahang. Tanarimba

is a sustainable housing project that blends

man-made and natural elements in an exciting

concept of ecologically sensitive community

development and also introduces the world to

eco-tourism opportunities inMalaysianhighlands. The project has been dubbed as the

forefront of the ecological movement in

construction (Tanarimba, 2006)


14/33

EXAMPLE OF THE DEVELOPMENT???

o DDC Project (Demonstration and Documentation

Centre for Sustainable Urban Household Energy

Usage), launched in 2004 by the Centre for

Environment, Technology and Development,

Malaysia (CETDEM). This project pioneered the

construction of urban energy saving house

(CETDEM, 2006). Malaysia Energy Centre

(PTM) has also embarked on energy-efficiency

building by constructing a zero energy officebuilding (ZEO) at Bandar Baru Bangi, Selangor

(PTM, 2006).


15/33

NOWADAYS DEVELOPMENT???

However, projects on sustainability inMalaysia

are mostly at the pioneering stage, indicating

thatMalaysia construction industry is still at

infancy when dealing with sustainability

matters.

However, government has stressed the

importance of sustainability in construction by

putting the clause under thrust #3 saying to

ensure a better Environmental Sustainabilityand ResourcesManagement.


16/33

THE DEVELOPMENT..TARGET???


17/33

WHAT IS THE DIFFERENCES BETWEEN

SUSTAINABLE DEVELOPMENT AND

SUSTAINABLE CONSTRUCTION???


18/33

TARGET??


19/33

BENEFIT???

Use natural resources efficiently

Creating healthier building that improve human

health

Built a better environment Provide cost saving

Protecting occupant health

Improving employee productivity

Reducing the overall impact to environment


20/33

SO, WHAT IS THE DISADVANTAGES???

1.Higher initial cost than ordinary

building.

oNot every project manage to get back

their overall net increase cost in a

short period

oSolution?? Life cycle cost should be

conducted to account for reduction of

operating cost & increase theproductivity

2.Lack of relevant skills & knowledge


21/33

PRINCIPLES OF SUSTAINABLE

CONSTRUCTION

Minimize resource consumption (conserve)

Maximize resource reuse (reuse)

Use renewable and recyclableresources(recycle/renew)

Protect the natural environment (protect nature)

Create a healthy, non-toxic environment (non-toxic)

Apply life cycle cost analysis and true cost

(economics) Pursue quality in creating the built environment

(quality)

Etc..


22/33


23/33

WHAT ELSE???

Enhanced biodiversity

Support communities

Use resources effectively

Minimize pollution

Create healthy environments

Manage the process


24/33

THE IMPACT OF CONSTRUCTION

INDUSTRY..??

Environmental biophysical environment,

enormous demands on global resources,

construction & demolition waste

Social

labor-intensive nature of constructionactivities; opportunities for poverty alleviation,

major role in human development

Economic normally would enhance economic

sustainability through its structure, conduct, and

performance until more than half of totalnational capital investment, can also enhance

environmental sustainability (least cost method,

optimal resource, discourage waste)

32/33

WHAT TO BE CONSIDERED

WHEN WE WANT TO START

MANAGING SUSTAINABLE

CONSTRUCTION???

There are some standard provided by US GreenBuilding Council (USGBC) such as Leadership inEnergy and Environmental Design (LEED), and

even Malaysian agency ( Persatuan ArkitekMalaysia).

PAM Just provide Green Building Index and theaccompanying Panel for certification andaccreditation of Green-rated buildings inMalaysia.
