Energy consumption parameter selection in architectural scheme design stage based on BIM platform

In architectural design, the selection and combination of architectural elements directly affect the cooling and heating load and the energy consumption of building equipment system. In order to guide the building energy saving design scientifically, and control the energy consumption of the building from the source, taking a typical office building as an example, presents the orthogonal experimental scheme, and obtains the building energy consumption index range with the different design parameters. All these works can provide some reference for BIM architectural design in the future，give full play to the advantages of BIM platform in the architectural scheme design stage, and achieve the rapid and efficient energy saving optimization design purpose.
