[摘　要]　中国目前正处于城市化进程的关键阶段，每年有大量的在施工程项目，施工过程的碳排不容忽视。结合施工实际，梳理施工过程的碳排影响因子，重点对施工现场的机械碳排进行量化。结合某项目案例，对其施工过程的碳排进行测算，并对各个分部分项工程的碳排进行分析对比，进一步提出施工阶段节能减排的宏观和微观措施。通过研究，探寻建筑施工节能减排的潜力，为建筑业节能减排提供参考。
[关键词]　建筑施工；碳排量化；节能减排
Abstract: China is currently in the critical stage of process of urbanization, many buildings are invested in construction each year, and the carbon consumption of construction process cannot be ignored. Based on the construction situation, this paper sums up the impact factors of carbon emissions for construction process, and quantifies the carbon emissions of construction machine. According to one villa project, this paper calculates the carbon emissions, compares the carbon emissions of each part, and then proposes the macro and micro energy saving measures for construction phase, in order to explore the energy saving potential for construction, and provide a reference for the implementation of the national construction industry's energy conservation work.
Key words: building construction; carbon emission; energy conservation
