1SUSTAINABLE ENERGY USAGE IN
MALAYSIAN URBAN HOMES: Reducing GHG
emissions
GURMIT SINGHChairman CETDEM
[cetdem@po.jaring.my]
2SUSTAINABLE DEV. POLICIES & PRACTICES
Minimize ecological footprints
Eliminate all forms of wastage
Optimize energy efficiencies & switch to renewables
Efficient, clean & affordable transport
Organic farming
Clean technologies [poll. prevention] as well as LCA assessments
Public participation, accountability & transparency
Conservation of all vital natural resources - from water to air
Eliminate hazardous wastes & products
REDUCE GHG EMISSIONS
3SOME SUSTAINABILITY INITIATIVES
Design & construction of Energy Efficient & cool buildings
Retrofitting of existing buildings
Integration of good mobility in new towns
Improvement of public transport in Klang Valley
Organic Farming Energy conservation
after audits Better Landscaping &
adequate green lungs Biodiversity
conservation esp. in nature parks
Proposed comprehensive Nat. Energy Policy

Idea is to keep the cool air in & hot air out (of & from the house)..
8Thermal Comfort - Sun Breakers
to block direct sunlight from heating up glass windows

SUSTAINABLE ENERGY USAGE
Contributes to reduction of GHG emissions as overall energy usage is curbed;
Should also affect the usage of construction material that has a low carbon footprint & if possible low transport-miles;
Accelerate the greening of the supply chain from the manufacturers up to final use.
22
SUSTAINABILITY OPPORTUNITIES for Const. Sector Comply with ISO14000
stds. Esp. dealing with EP & LCA;
Try to achieve energy efficiency levels of MS1525 for office buildings;
Comply with occup health levels in OSHA;
Demonstrate Care for the Environment
Monitor env conditions during construction & in vicinity of work sites;
Ensure construction waste is minimal & re-use as much as possible;
Avoid open-burning & illegal dumping;
23
SUST. OPPS. [ctd] Observe diligently env
mgmt plans, whenever they exist or develop on own initiative;
Be responsive to any complaints from workers or occupants /residents of neighbourhood;
Insist on vendors / suppliers observing good env practices;
Publish detailed CSR reports & ensure adequate distribution;
Take pride in environmental performance & care!

The Malaysian Scene
25
Developers & civil engineers just refuse to build along contours. Their levelling craze is worsened by the unwillingness to protect bare soil. Hence the ever common
EROSION & SILTING-UP of drains & rivers
26
WHERE ARE THE WORKING SILT-TRAPS?
Can anyone name a specific site where soil erosion is prevented? Where silt-traps are adequate in nos & fully maintained?
Do developers/ constructors fully compensate the community for damage caused by resulting floods?
Are do they just pass the buck to someone else?
27
DO CONSTRUCTORS PROVIDE
Adequate & safe transport facilities for their staff?
Enough accommodation for their site workers? Satisfactory slope protection and environment-
friendly drainage systems at sites? Enough protection to staff & passerbys at their
sites?
END 28
DO MALAYSIAN ENTITIES CARE?
Not many vie for the Hibiscus Award
How many winners have sustained their efforts?
CSR reports are NOT the norm
Financial institutions virtually ignore people & environment [with a couple of exceptions]
Support is more forthcoming for GREEN rather than BROWN issues
Only project rather than programme funding for env. NGOs
Little public disclosure instead confidentiality invoked !
