What is Sustainability?
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Brundtland Commission report of 1987

WHAT ARE THE KEY ISSUES FOR MALAYSIA?
KEY ISSUES FOR MALAYSIA Urban Population expected to grow by between
40% to 50% by 2030 from 70% to 80% of Total Population. The way we plan our Cities will be a Key component of a sustainable future
24% of Urban Home Energy consumption is from the use of the Car to & from work
31% of Urban Home Energy consumption is from the use of the Car for after work
Malaysia will become a Net Importer of Energy by 2015. How we design our homes will reflect how much energy they require to run.

OVERVIEW OF ENERGY USE IN MALAYSIA
Petronas supplies gas to TNB at a discount of 76% international market rates
71% of power stations rely on natural gas If gas were supplied at international rates to
power stations, Electricity Tariffs would increase by 25%
Electricity Tariffs were last increased by 12% on 1st June 2006

Public Transport Availability
Proximity of Basic Services such as Mini Markets, Schools, Places of worship, Libraries, Sports facilities, Community Halls and Parks, Transport Hubs
Sufficient Green Open Spaces to counter the Urban Heat Sink effect
Construction Systems that encourage IBS
Storm Water management to prevent Localized Flooding
Avoiding environmentally sensitive areas
Re-development of Brownfield sites rather than opening new sites

SITE PLANNING & MICRO-CLIMATE
Urban Heat Island Effect : Case Singapore
Green Malaysia GBI Residential 7-3-09 14
A parameter that measures the Energy Efficiency of the Building without inhibiting the design options and creativity of the Architect is used that is RTTV and OTTV
The Sun, Heat and High Humidity are the key elements Architects have to deal with for the Malaysian Climate
A low RTTV and OTTV means overall a lower heat gain into the home and therefore a a lower Air conditioning load and less hours of operation.
Use of renewable energy such as solar hot water systems and photo-voltaic panels is rewarded
Encourage the development which discourage commuting and encourage work from home
2. ENERGY EFFICIENCY
ROOF INSULATION IS ONE OF THE MOST IMPORTANT DESIGN DECISIONS FOR ENERGY EFFICIENT BUILDINGS
The roof plane receives the most Solar Radiation and for the longest period through the day
>75% of the Solar Gain by a typical Intermediate Single Storey Terraced House is through its ROOF
>50% of the Solar Gain by a typical Intermediate Double Storey Terraced House is through its ROOF
>40% of the Solar Gain by a typical 5 Storey Bock of Flats is through its ROOF

5. WATER EFFICIENCY
Green Malaysia GBI Residential 7-3-09 17
The average Malaysian uses 300 liters of water a day, double therecommendation by United Nations and more than twice the average Singaporean.
Selangor, KL & Putrajaya projected to face water stress as early as 2009 when demand reaches 4,375 mil liters while supply is at 4,336 mil liters.
This is projected to remain until 2013 when Langat 2 increases supply by 1,000 mil liters.
Most water shortages are cause by uneven people-water distribution.
In the most densely populated states, the river basins have reached their limits for maximum supply, but demand continues to raise.
