国内建筑碳排放计算标准对比分析
Comparative analysis of domestic building carbon emission calculation standards
摘要：
在“双碳”战略驱动下,我国建筑碳排放计算标准进入密集更新阶段。本研究基于全生命周期理论框架,系统对比了国内现行6部建筑碳排放计算标准,重点从计算边界、计算方法及计算参数3个核心维度解构标准间的共性与差异性。研究发现,各标准在运行阶段精细化计量、比例系数估算、新型建材和新型建造方式碳排放因子、地域性碳排放强度指标数据库建设等方面都有创新突破。研究成果不仅为建筑全生命周期碳排放计算提供了多维度方法选择,也为推动行业碳排放计算标准迭代升级提供了优化思路,具有一定指导价值。
Abstract：
Driven by the “dual carbon” goals, China’s building carbon emission calculation standards have entered a phase of intensive updates. Based on the whole life cycle theory framework, this study systematically compares six current domestic building carbon emission calculation standards, with a focus on deconstructing their commonalities and differences across three core dimensions: calculation boundaries, calculation methods, and calculation parameters. The study finds that various standards have achieved innovative breakthroughs in areas such as refined operational phase measurement, proportional coefficient estimation, carbon emission factors for new building materials and construction methods, and the development of regional carbon emission intensity indicator databases. The findings not only provide multi-dimensional methodological options for whole life cycle carbon emission calculation in buildings, but also offer optimization pathways to promote iterative upgrades in industry carbon emission calculation standards, demonstrating significant guiding value.
