| Abstract |
Building simulation has enormously developed over the past three decades. Building simulation tools can describe mass and heat transfer phenomena in buildings with high accuracy. However, such tools are not widely and pervasively used in the design firm on daily basis. At most, the tools are being used for code check or green building accreditation, not being iteratively used throughout the whole building design process for better decision making. This paper reports three factors (external, internal, technical) to investigate the aforementioned issue. For this purpose, the authors utilized international literature and domestic surveys. The external factor includes tight schedule, limited budget and cost, overloaded and ill-informed staff, and lack of education and proper training. The internal factor includes differences in knowledge and praxis between designers and simulationists. The technical factor includes steep learning curves and user-unfriendly interface of simulation tools, language barrier in program manual, lack of modeling information and library suited for domestic circumstances. Finally, in the paper, it is elaborated what should be done for better use of building simulation tools in the design process. |
