As the issue of global warming becomes more substantial, office buildings in Malaysia widely use air conditioning as an active design solution to cool the building. However, thermal comfort is often a problem in many offices using centralized air conditioner where occupants complain that the indoor climate is too cold. The overcooling effect is a result of over-specification of air conditioning systems, which lead to inefficient energy consumption and thermal discomfort. This paper identities and explains the underlying causes of over-specification. The investigation focuses on understanding the factors affecting active design decisions. A total of 39 construction consultants participated in face-to-face interviews that were conducted in individual and group meetings. Research 􀏐indings revealed that the problem can be attributed to the practice of quick solutions, resistance from design consultants, a ‘bigger is better’ mentality, unsupportive fee structures, and poor testing and commissioning practices. The highest contributing factor is the resistance of design consultants to change and consider new solutions that break away from customary practices.
