Global warming has become a matter of great concern worldwide. One of the major contributor to the problem is uncontrolled release of global warming agent, carbon dioxide (CO2).The harmful CO2 which is also a greenhouse gas is released into the atmosphere each time the power plant generate electricity. One of the ways to address this issue is by building innovative sustainable buildings or buildings that use energy efficiently. Efficient use of energy will reduce the rate of harmful CO2 emission and contribute towards a better environment.
Building are responsible for approximately 40% of the greenhouse gas emission into the environment due to the embodied energy used during its construction and operation. The lifespan of a building is normally up to a half century or more. The longer its lifespan, the higher accumulated energy is used and more CO2 is released into the atmosphere.
The degree of energy efficiency of a building is normally measured and compared in Building Energy Index (BEI). The BEI is expressed in total energy used, which is normally the total kWH of electricity per square metre per annum (kWh/m2/year) of the building’s net area. An energy efficient building should aim for a lower BEI. In Malaysia, the recommended BEI of an energy efficient building is not more than 100 kWh/m2/year.

The Green Energy Office (GEO) building is the first government building design with capability to generate its own energy from green energy sources. It has been designed to demonstrate the extent to which energy efficiency (EE) features can be exploited to achieve a low Building Energy Index (BEI) and incorporates extensive use of renewable energy through the use of solar photovoltaic power generation. The objective of the building project is to demonstrate the intensive use of EE in lowering the energy consumption and RE to generate most of the energy needs from green energy source. This is based on the economic and fuel price scenario within the next 10 to 15 years.
The Low Energy Office (LEO) building is the first government energy efficient building designed in 2001 with integrated EE features. The objective of the building project is to demonstrate the feasibility of an EE building without compromising user’s comfort with current economic scenario. A number of known and proven energy efficiency technologies has been incorporated into the design of the building and has achieved it Building Energy Index of 100 kWh/m2/year.
The Diamond Building is the first government building to be designed with integrated green building features. It is designed to have a Building Energy Index (BEI) of 85 kWh/m2/year as well as to incorporate solar photovoltaic system to generate clean electricity upon its completion in 2010.
A special feature of the building is the “inverted pyramid” concept, which creates extensive shading of the building to reduce heat gained from the sides of the building. It will also enhance the use of daylight to minimise the use of artificial lighting. The cost-effective Diamond Building received provisional “Green Building Index Platinum” rating based on its unique design and green building features.
