摘要:

为了解夏热冬冷地区绿色公共建筑的资源消耗水平和能源利用效率,筛选出位于夏热冬冷地区的35个获得绿色建筑标识并投入运行的公共建筑项目,通过数据调研、现场核实等方式获取了项目的运行数据,量化分析了绿色建筑运行中的资源消耗数据及关联性因素,并与相关标准和统计数据进行了对比。从样本项目的分析结果来看,与普通公共建筑相比,投入运行的绿色公共建筑有明显的节能优势和较好的节水效果。绿色公共建筑能耗与星级的关系不明显,与合理的增量成本投入呈负相关关系,与可再生能源利用、空调形式选择、运营管理水平有密切关系;绿色公共建筑运行中过高的用能负荷、设备运行效率低、设备与负荷不匹配都会提高能耗水平。在此基础上提出了降低绿色公共建筑资源消耗、提高能效的措施和建议。

Abstract:

In order to acquaint the resource consumption level and energy efficiency of green public buildings, selects thirty-five operating public buildings with green building logo in hot summer and cold winter zone. Obtains the operating data of the buildings through the data research, on-site verification and other ways, quantitatively analyses the resource consumption data and the related factors during the operation of green buildings, and compares with the relevant standards and statistical data. The analysis results of the sampling projects indicate that, compared with the general public buildings, the operating green public buildings have obvious energy saving advantages and better water saving effect. The energy consumption of green public buildings has less relationship with the level of green star and negative correlation with the reasonable increment cost, but closely related to the renewable energy utilization, the air conditioning forms and the operational management level. High operating load, low equipment operating efficiency, and mismatching between load and equipment in green public buildings will increase their energy consumption level. On this basis, puts forward the measures and suggestions to reduce resource consumption and improve energy efficiency of green public buildings.
