Abstract: Abstract Building energy consumption is increasing great over time so that we need to take measures to reduce it. Building energy analysis and evaluation is the premise to realize building energy-saving. Calculating the heating or cooling load by static algorithm is a traditional method to do building energy analysis. This method ignores the delay and attenuation of heat transfer so that it’s not accurate as well as unsustainable. According to BIM’s completeness of information, good visualization and sustainability, a method to evaluate building energy based on BIM is presented in this paper. Firstly, BIM technology and it’s research status are introduced. Secondly, a framework to explain how to analyze and assess building energy by BIM software is presented. Then, a teaching building in Hefei is taken as an example, and it’s building energy evaluation is done with Ecotect. Some energy-saving measures are put forward finally. This article provides some ideas and methods for evaluating building energy in hot summer and cold winter region.
