An overview of an integrated building simulation tool -designer’s simulation toolkit (dest)

In early 1980s, Tsinghua University has started to develop a new building simulation tool with the aims to benefit for teaching, research and practical use of HVAC related applications in China. With the concept of “base temperature” of a space, it provides a handy link between thermal behaviour of buildings and dynamic performance of HVAC systems. It emphases on finding the predicted ideal performance of a system and compare with the user selected design conditions of a space, ie the degree of satisfaction, rather than go straight to find the size and capacity of the system. This paper reviews the theory and main features of DeST.
