ABSTRACT: The main objective of energy efficiency in building design is to use the minimum amount
of energy while meeting thermal comfort standards. The most fundamental and effective design
principle to reduce heat gains for a building in Hot Humid climates is to orientate the building to take
maximum advantage of prevailing breezes for ventilation and for the reduction of heat gains from direct
solar radiation for better comfort of the occupants.

A survey using questionnaires and interviews was conducted in a terraced housing area to investigate
the correlation between orientation of the subdivision and energy consumption and thermal comfort of
the occupants. A total of seventy-three households from houses of various orientations were
interviewed and the findings form part of the present research investigations. It is expected that the
information on the correlation between orientation and energy consumption will provide the foundation
on which energy efficient design can be developed for terraced housing in Malaysia. The results
revealed no strong correlation between orientation of a building and its energy consumption, however
buildings facing directions of prevailing winds are more likely to benefit, through physiological cooling,
the effects of comfort ventilation.
