上海近零能耗居住建筑技术指标研究
Study on technical indicators of nearly zero energy residential buildings in Shanghai
摘要：
在“碳达峰、碳中和”国家发展战略背景下，发展近零能耗建筑已成为建筑领域节能减排的发展方向。由于地域气候和用能习惯上的差异，有必要开展适用于上海地区的近零能耗建筑技术指标研究。本文在上海市超低能耗建筑技术体系的基础上，通过典型居住建筑案例分析，提出了适用于上海的近零能耗居住建筑技术指标建议：建筑综合能耗指标为48～50 kW·h/(m2·a)，供暖年耗热量和供冷年耗冷量指标值分别为5 kW·h/(m2·a)和25 kW·h/(m2·a)；可再生能源利用率指标应根据空气源热泵热水供热是否计入可再生能源来确定。
Abstract：
Under the background of the national development strategy of “carbon peaking and carbon neutrality”, the development of nearly zero energy buildings has become the development direction of energy conservation and emission reduction in the building field. Due to the differences in regional climate and energy consumption habits, it is necessary to carry out the research on the technical indicators of nearly zero energy buildings suitable for Shanghai. Based on the technical system of ultra-low energy consumption buildings in Shanghai, this paper puts forward the technical index suggestions for nearly zero energy residential buildings applicable to Shanghai through the case analysis of typical residential buildings. The comprehensive energy consumption index of the building is 48-50 kW·h/(m2·a), and the annual heat consumption for heating and the annual cold consumption for cooling are set at 5 kW·h/(m2·a) and 25 kW·h/(m2·a), respectively. The renewable energy utilization rate index should be determined according to whether the hot water heating of the air-source heat pump is included in the renewable energy.
