This model is called ID3 model. Based on the three basic models of Stepwise, Apriori-rule and ID3, an integrated model of building's energy consumption benchmark evaluation called SAI-Voting is proposed by voting. However, the model is too complex, and there is still a problem of low accuracy of energy consumption testing. In reference [4], a Revit-based energy consumption simulation software for complex buildings is proposed. This software has good advantages in sunlight irradiation and radiation, can read directly the documents exported by Revit, and can return the data directly to Revit. Although the energy consumption simulation software will have a very good development trend in the process of complex building design, there is the problem of low accuracy of energy consumption measurements.
