This paper analyzes the energy consumption simulation based on BIM by researching a lot of documents. BIM is used to construct various building models to conduct the comparative analysis. The horizontal sunshade of the building is 487 mm. When the heat transfer coefficient of outside window materials reduces, the annual energy consumption of per square meter drops from 237.78 k Wh/m2 to 206.89 k Wh/m2. BIM is used to assist the architectural design, which can directly analyze and design the energy consumption with strong practicab
