Buildings consume a very high
percentage of energy compared
with other economic sectors.
Although the percentages vary
among countries, buildings are
responsible for between 30% and
45 % of global energy demand. The
high rate of energy consumption
and carbon dioxide emission in
building environments have made
energy efficiency and cost-saving
strategies a priority objective for
energy policies for most countries.
E
fficient use of electricity in Government
buildings is one of the Malaysian
Government’s efforts to manage the
country’s energy resources efficiently and
effectively. This is important because our country
has seen rising energy consumption in line with
its rate of economic development. The world is
facing challenges due to decreasing fossil energy
sources such as oil, gas and coal, while prices are
rising. Therefore, the Government must lead the
effort to use energy efficiently.
The typical portion of energy in Malaysian
office buildings is 50% for air-conditioning, 25%
for electrical lighting and 25% for small power
consumption i.e. electrical equipment. In addition,
air-conditioning energy consumption is not only
due to solar heat in the building, but also due to
heat emission from electrical lighting, electrical
