以北京市东城区某综合园区为例,根据园区现状对其围护结构热工性能、供暖空调、建筑照明及用水器具进行节能诊断及能耗分析.结果显示:建筑供暖耗热量及照明耗电量占比分别为58.96%和10.24%,为挖掘改造潜力并确定基准能耗提供了依据;通过围护结构保温层加装、门窗更换、高效空调设备更换、照明灯具更换及节水器具更换等节能技改措施进行综合节能改造,计算改造后能耗;将不同能源类型能耗归一化为标煤,经测算,改造后项目节能量约为71.0 tce,综合节能率35.52%,减少向大气排放二氧化碳175.38 t,节能减排效果显著,为类似地区公建节能改造提供了借鉴和参考.本次能评估多采用理论模拟计算方法,还需改造后实际运行数据对比支撑.
A comprehensive park in Beijing is analyzed to conduct energy-saving diagnosis and energy consumption analysis based on the current enclosure structure,heating and air conditioning,building lighting,and water appliances.The results show that the proportion of heating and lighting energy consumption in buildings is 58.96%and 10.24%respectively.The data provides a basis for exploring the potential of transformation and determining benchmark energy consumption.Comprehensive energy-saving transformation is carried out through technical transformation measures such as installation of insulation layer of enclosure structure,replacement of doors and windows,replacement of high-efficiency air-conditioning equipment,replacement of lighting lamps and water-saving appliances,etc.The energy consumption of different energy types is normalized to standard coal.After calculation,the energy savings of the modified project are approximately 71.0 tce,the comprehensive energy-saving rate of the reconstructed project is 35.52%,which provides reference for similar energy-saving reconstruction projects of public buildings in the region.The energy efficiency evaluation mostly adopted theoretical simulation calculation methods,and required comparison and support of actual operating data after retrofitting.
