ABSTRACT: Due to the need of low-carbon design for public buildings and carbon emissions measurement, the article constructed low-carbon design analysis for public buildings and carbon emission measurement models based on BIM, and established low-carbon design analysis process of public buildings; with a sample of public buildings as an example, the article analyzed geographical environment impact on building and architecture noumenon energy-saving effect, including building’s thermal performance and architectural light environment analysis, obtaining the optimization strategies for low-carbon design. With the establishment of public building measure carbon emissions inventory and analysis processes, the study respectively calculated carbon emissions in three stages including construction, operation and dismantling, obtaining a total value of carbon emissions for building life circle. Then the article analyzed carbon emissions contribution of public buildings’ life circle, pointed out that reducing the energy consumption of public buildings lifecycle operations phase is the most important measure to control and reduce carbon emissions in public buildings. The research results provided empirical reference for further low-carbon design of public buildings and building carbon emission measurement standard of public buildings.
