Review of building performance simulation methods in conceptual design period

Reviews the research achievement of energy saving design in the fields of building performance simulation methods in conceptual design period, including process analysis of design by simulation, simulation of microclimate around buildings, single building performance simulation and performance evaluation method. Analyses the deficiencies of present study methods, and points out that to solve these problems, the process of design by simulation should be discussed and the availability of input parameters in conceptual design period needs further analysis. Moreover, uncertainty analysis should be considered in building performance simulation.
