Building environment design simulation software DeST(2): dynamic thermal process of buildings

Explains the dynamic building thermal process model of DeST based on state space solution method. Starts with a presentation of problems to be encountered and the equations to be solved when constructing such a thermal process model. Points out that it is imperative to solve the heat transfer equations of opaque envelopes correctly and consider the interaction among components in a room and among rooms in a building in details. Then describes detail procedures on how to solve these problems and how to carry out a building thermal environment simulation by DeST with some examples. Finally compares the state space method with other solution methods.
