|Summary:||This research has been carried out with the aim to investigate ho\\· high rise ollice building
design in tropical climate can contribute in reducing energy consumption \\·hile maintaining
comfort. The main objective of this study is to compare the performance of a sample \11'
bioclimatic high rise office blocks with that of conventional ones when situated in a tropical
climate such as that in Malaysia. The research firstly reviewed all the characteristics of
bioclimatic buildings in the Malaysian Peninsula particularly the traditional ~lalay house and
the transformation through time. Secondly. the research studied some design planning and
architecture of several high-rise office buildings principally the bioclimatic approaches.
Thirdly, the claimed benefits of bioclimatic design approach for high rise office buildings
were examined in the results of previously conducted research projects. dealing with energy
consumption and design approaches which compares the bioclimatic and con\·entional high
rise. The performance was measured according to a combination of technical and social
criteria: direct observation on various architectural aspects. environmental measurement and
users' perception of comfOl1 and satisfaction with their working enyironment \·ia
questionnaires. The energy consumptions were compared based on the electricity bills
recorded for at least a year period. The local building energy index is used as the benchmark
to check whether there were real energy savings in the bioclimatic high rise office blocks or
otherwise. The major finding of this work is that the occupants in bioclimatic high rise oflice
buildings have a higher level of satisfaction with their working environment than those in
conventional office blocks. There is evidence that bioclimatic high rise office buildings are
energy efficient as the most recent bioclimatic high rise office building U\'1cnara L~l0:()).
has a lower energy index than the ASEAN standard and within the latest Malaysian Standard
related to energy efficiency. In the past. high rise buildings have been perceived as
inefficient users of energy, with the new bioclimatic design concept and technologies. there
is no doubt that high rise office buildings in the future would be much beller in design that
provide better environment to the users and consume less energy.|
