摘要
据统计,建筑运行阶段的碳排放占总碳排放比例为28%,对我国实现“二氧化碳排放力争于2030年前达到峰值,努力争取2060年前实现碳中和”的目标至关重要,而建筑运行阶段也确实有较大节能潜力。故基于寒冷地区某城区当前民用建筑的建筑类型、节能标准执行情况、项目设备选用情况、运行阶段能源消费水平以及城市碳排放指标体系等基础数据,采用四分位统计方法,应用LEAP软件对碳达峰的路径进行仿真和情景分析,制定符合此城区实际运行情况的民用建筑动态碳排放基准线。研究实施方案和策略,并搭建能源管理平台对建筑进行精细化控制和管理。经过测算,2030年有望实现碳达峰,城镇住宅、政府办公、中小学、幼儿园、普通办公、商业、文体设施、星级酒店、医疗建筑的碳排放基准线分别为50.52kgCO_(2)/m^(2),129.92kgCO_(2)/m^(2),68.27kgCO_(2)/m^(2),96.15kgCO_(2)/m^(2),59.67kgCO_(2)/m^(2),136.31kgCO_(2)/m^(2),146.99kg CO_(2)/m^(2),132.73kgCO_(2)/m^(2),164.37kgCO_(2)/m^(2)。
According to statistics,the carbon emission in the building operation stage accounts for 28% of the total carbon emission.So reducing building energy consumption is very important for China to achieve the goal of "carbon peak in 2030 and carbon neutralization in 2060".Zero energy consumption building is the future development trend,which relying on renewable energy without conventional energy consumption.Therefore,basing on the basic data of the current civil buildings in an urban area in the cold area,such as the building type,the implementation of energy-saving standards,the selection of project equipment,the energy consumption level and the urban carbon emission index system,the paper formulates the dynamic carbon emission baseline of civil buildings with the actual operation of this urban area.Using the quartile statistical method,the path of carbon peak is simulated and analyzed by LEAP software.At the same time,the implementation scheme and strategy are studied,and an energy management platform is built for fine control and management of the building.It is estimated that the carbon peak is expected to be achieved in 2030.The carbon emission baseline of urban housing,such as government office,primary and secondary schools,kindergartens,general office,commerce,sports facilities,star hotels and medical buildings are 50.52kgCO_(2)/m^(2),129.92kgCO_(2)/m^(2),68.27kgCO_(2)/m^(2),96.15kgCO_(2)/m^(2),59.67kgCO_(2)/m^(2),136.31kgCO_(2)/m^(2),146.99kgCO_(2)/m^(2),132.73kgCO_(2)/m^(2),164.37kgCO_(2)/m^(2).
