夏热冬暖地区典型办公建筑低碳化技术及减碳量评估
Low-carbon technologies and carbon reduction assessment of typical office buildings in hot summer and warm winter zone
摘要：
降低建筑运行阶段的二氧化碳排放量对于建筑行业乃至社会全行业实现碳达峰碳中和目标至关重要。本文聚焦夏热冬暖地区的办公建筑，就建筑运行阶段低碳化技术在不同体量办公建筑中的适用性及二氧化碳减排水平展开研究。能耗模拟和碳排放量计算结果表明：在夏热冬暖地区，主动式低碳技术的减排潜力高于被动式技术，其中空调系统能效提升的减排效果在不同体量的建筑中均较为显著；高效照明和高效电梯技术的减碳水平随办公建筑体量的增大分别呈上升和下降趋势；小体量建筑能够通过铺设屋面光伏板大幅减少外购非绿电造成的间接碳排放。
Abstract：
Reducing the CO2 emissions in the building operation stage is crucial for the construction industry and even the whole society to achieve the goal of carbon peak and carbon neutralization. This paper focuses on office buildings in hot summer and warm winter zone, and studies the applicability of low-carbon technologies in different volume office buildings and the level of CO2 emission reduction. The results of energy consumption simulation and carbon emission calculation indicate that the CO2 emission reduction potential of active technologies is higher than that of passive technologies in hot summer and warm winter zone. Especially, the increase in air conditioning energy efficiency leads to a significantly higher CO2 emission reduction rate among all the building volumes discussed. Meanwhile, the CO2 emission reduction rates of efficient lighting and efficient lift will ascend and descend with the increase of building volume, respectively. The indirect CO2 emission from the purchased non-green power of smaller volume buildings can be dramatically reduced by installing photovoltaic panels on the roof.
