| 为探究夏热冬冷地区近零能耗公共建筑能耗特征及降耗技术路线,选取温州某近零能耗办公建筑为研究对象,利用eQUEST建筑能耗模拟软件并根据GB∕T 51350—2019等相关规定,首先对项目基准建筑与设计建筑全年能耗进行仿真模拟,分析其能耗构成和能耗特点,然后对冬夏季能耗占比最大的外窗负荷进行研究；其次探讨了建筑全年用电构成及降耗技术路径；最后计算了建筑碳排放水平、本体节能率、综合节能率及可再生能源利用率。通过以上途径,实现了项目近零能耗建筑的设计目标,判断了建筑碳排放水平。研究结果为建筑节能专业人员合理选择技术路线,进行近零能耗公共建筑的设计提供参考建议。
| In order to explore the energy consumption characteristics and consumption technical routes in the nearly zero-energy consumption public building in the summer cold area, model selects a nearly zero- energy- consuming office building in Wenzhou as the research object, uses eQUEST building energy consumption simulation software and relevant provisions in the national standard GB/T51350. First of all, it stipulates that the energy consumption simulation of the project and design building of the project yearly, analyzes its energy consumption composition and energy consumption characteristics. Then it studies the largest outer window load, electricity composition and consumption technology path in winter and summer. Finally, it calculates the level of carbon emissions, the energy saving rate of the body, the comprehensive energy saving rate and the utilization of renewable energy, through the above channels, and achieves the design goals of the nearly zero energy consumption building of the project, also judges the carbon emission level of the building. The results of the research energy-saving professionals selects the technical route reasonably, and provides reference suggestions for the design of nearly zero energy consumption public buildings.
