ENERGY PERFORMANCE OF THREE RESIDENTIAL COLLEGE BUILDINGS IN UNIVERSITY OF MALAYA CAMPUS, KUALA LUMPUR

Abstract

Three residential collegeslocated in Kuala Lumpur, Malaysia, were selected for energy performance
analysis in regards to its implementation of bioclimatic design strategies. Specifically, passive design
strategies on daylighting and natural ventilation were examined. In Malaysia, the residential college or
hostel is a multi-residential building providing accommodation to university students. The three
residential colleges in this study, namely C1, C2 and C3, were built in different years with different
designs and forms, particularly with regards to enclosure and facade design, solar control devices,
passive daylight concepts, and natural ventilation strategies. The building designswere carefully studied
and an electric consumption analysis was carried out in each residential college. This study revealed
that the wide-scale implementation of bioclimatic design strategies in college C2 help reduced the
annual energy consumption. The building bioclimatic design features that are accountable to reduce
energy consumption are the internal courtyard and balconies on each unit of floor area, as shown in
C3.Results from this study highly recommend internal courtyard and balcony building combinationfor
multi residential building design, especially in tropical urban regions.
