energy consumers in hot and humid countries like Malaysia. For building complexes
such as those in a university, the cooling energy varies depending on the varying
activities of students and staff. Some of these buildings are intentionally
designed and built by architects for aesthetic values and those with building
envelope that comprises large areas of glazing consequently face high energy
cost of air-conditioning due to the high heat gain through solar radiation.
Due to the present uncertainties in the cost and availability of local and global
energy, along with the environmental problem related to global warming, studies
on how to reduce cooling energy in highly glazed buildings are imperative. The
objective of the present work is to study a few possible strategies to reduce
energy consumption through the air conditioning systems in a highly glazed academic
building. The strategies considered in the study are through forced reduction
of air-conditioning load during lunch-time and during rain and also by switching
off some of the lights during office hours. The study is conducted by computer
simulation using EnergyPlus software which estimates the cooling energy of a
building or areas. It is found in the study that the strategies for reduction
of cooling energy have potentials and are practical for implementation in the
buildings.]]>Malaysian Standard MS1525,20072007DuPont,20102010EnergyPlus,20102010Eskin, N. and H. Turkmen,200840763773Lam, J.C.,2000351926Lee, K.H. and J.E.
