Energy Overview on Building: In Malaysia, almost50% of total electricity generated consumed byresidential and commercial sector.

According to MGTC, the commercial building consumed one-third of allelectricity in ASEAN region and will account for more that 40% of the

demand for additional generating capacity in near future.

In a conventional building, 60-70% electricity consumed by lighting and

Air-Conditioning & Mechanical Ventilation (ACMV) and the rest remainingare plug loads, food preservation/preparation and equipment.

What is sustainability and why is it important?

The United Nations Brundtland Commission Report (1987) defined

sustainable development and urged the world to take note: Sustainable development is that which meets the needs of thepresent without compromising the ability of future generations to

meet their own needs. A growing global population is straining the

finite resources available on the planet. Sustainability seeks to balancethe economic, social, and environmental impacts, recognizing thatpopulation growth will continue. Sustainable development brings thisevaluation to the design and construction industries, which have

significant potential to reduce the negative impact of human activitieson the environment.

The importance of Sustainable Development andGreen Technology are highlighted by our YAB

Prime Minister during the opening speech of

IGEM 2010 as:

1. Green Technology to become new engine of growth for

Malaysia2. Reduce global green house gas emission by 30% in

2020

3. Increased investments in green technology will alsomake available a wider scope of eco-products and

services
