以某既有公共建筑节能改造为例,对比改造前后全年耗电量及分项能耗,分析不同节能改造措施对应的节能效果;通过改造后现场温度实测,分析说明围护结构改造后对室内热环境的影响。研究结果为夏热冬冷地区既有公共建筑节能改造方向和节能改造重点提供参考。 Take the energy-saving retrofit of an existing public building as an example, comparing the annual electricity consumption and energy consumption before and after the retrofit, and analyzing the energy-saving effects corresponding to different energy-saving retrofit measures. By means of on-site temperature measurement after reconstruction, The impact of indoor thermal environment. The results provide reference for the retrofit direction and energy-saving renovation of existing public buildings in hot summer and cold winter area.
