夏热冬冷地区幼儿园建筑运行碳排放和经济性分析

Carbon Emission and Economic Analysis of Kindergarten Building Operation in Hot Summerand Cold Winter Areas

幼儿园建筑运行与与常规建筑相比具有显著区别,通过识别碳排放源,明确运行阶段碳排放边界,基于能源消耗情况开展碳排放测算,得出以下结论:厨房设备能耗最大占49.43%,空调系统能耗占21.28%,照明系统能耗找18.07%,电风扇能耗占10.87%。结合运行特点、用能情况等,对各类用能设备开展减碳改造和实施经济性分析,实践表明:采用空调和风扇联合运行策略及更换高效照明灯具具有显著的减碳效益。

The operation of kindergarten buildings was significantly different from conventional buildings.Identified the sources of carbon emissions,clarified the boundary of carbon emissions in the operation stage,and carried out carbon emission measurement based on energy consumption,the following conclusions were drawn:Kitchen equipment consumes the largest 49.43%of energy,air-conditioning systems consume 21.28%,lighting systems consume 18.07%,and electric fans consume 10.87%.Combined with the operational characteristics,energy use,etc.,various types of energyusing equipment to carry out carbon-reducing renovation and implementation of economic analysis,practice showed that:the use of air-conditioning and fan joint operation strategy and the replacement of high-efficiency lighting fixtures has a significant carbon-reducing benefit.
