现役住宅碳排放研究进展

Research Progress on Carbon Emissions from Existing Residential Buildings

摘要: 本文针对住宅建筑在运行阶段的碳排放问题展开研究，探讨了住宅运行阶段的碳排放来源、影响因素以及减碳策略。通过对主要能耗来源、围护结构节能改善、国内外碳排放因子差异以及住宅减碳优化策略的分析，得出住宅运行阶段在现役住宅碳排放量中占比最大，能耗主要来自供暖与制冷。围护结构对住宅碳排放影响显著。国内外碳排放差异表明我国可借鉴清洁能源利用和立法促进建筑减排。生态绿化和可再生能源利用是重要减碳策略。未来研究应考虑居民生活习惯、围护结构材料更新和维护材料选择等因素，以实现住宅建筑的低碳发展目标。住宅减碳是重要课题，需平衡环境效益和经济效益，促进绿色建筑行业发展。

Abstract: This paper examines carbon emissions during the operational phase of residential buildings, exploring the sources, influencing factors, and carbon reduction strategies. By analyzing the main sources of energy consumption, energy-saving improvements to building envelopes, differences in carbon emission factors between China and abroad, and optimizing carbon reduction strategies for residential buildings, it is concluded that the operational phase accounts for the largest share of carbon emissions from existing residential buildings, with energy consumption primarily coming from heating and cooling. Building envelopes have a significant impact on residential carbon emissions. The differences in carbon emissions between China and abroad suggest that my country can learn from clean energy utilization and legislation to promote building emission reduction. Ecological greening and renewable energy utilization are important carbon reduction strategies. Future research should consider factors such as residents’ living habits, building envelope material upgrades, and maintenance material selection to achieve the goal of low-carbon development for residential buildings. Residential carbon reduction is a critical issue that requires balancing environmental and economic benefits to promote the development of the green building industry.
