在满足室内环境热舒适要求的同时，节约空调能耗对于建筑节能至关重要。本文根据人体服装调节行为，提出了适应气候变化的动态设定温度（DST），即室内空调设定温度随室外气温动态变化；此外。建立了获取DST的方法。首先根据历史温度预测日平均服装隔热性，然后根据变化的服装隔热性计算室内热舒适温度，最后确定夏令时。根据热舒适度对应的预测平均投票值或范围（0、-0.5~0.5、-1~+1），定义了三个级别的DST。相应的热可接受率分别为95%、90%和73%。根据2017年气象资料，对中国长沙市某公共建筑进行了夏令时模拟，得到了三级夏令时范围，分别为I级20.1~27.8℃、II级17.8~28.7℃和III级15.4~29.7℃。运行空调能耗模拟结果表明，采用DST比传统的固定设定温度（FST）可节省高达65.5%的能耗，采用三级DST使运行能耗比一级DST降低59.1%。因此，本文提出的DST在满足热舒适性要求的同时具有显着的节能潜力。
Saving energy consumption of air-conditioning is essential to building energy conservation while satisfying the thermal comfort requirements of indoor environment. On the basis of human clothing adjustment behavior, a dynamic setting temperature (DST) that adapts to climate change was proposed in this paper, i.e. indoor air-conditioning setting temperature changes dynamically with outdoor air temperature; furthermore. A method was established to obtain the DST. The daily mean clothing insulation was predicted according to the historical temperature at first, then indoor thermal comfort temperature was calculated based on the variable clothing insulation, and finally the DST was determined. According to the value or range of predicted mean vote (0, -0.5~0.5, -1~+1) corresponding to the thermal comfort, three levels of DST were defined. The corresponding thermal acceptability rates were 95%, 90% and 73%, respectively. A simulation of DST was conducted in a public building in Changsha, China based on meteorological data of 2017. Three levels of DST ranges were obtained, varied from 20.1 to 27.8 °C in level I, 17.8 to 28.7 °C in level II and 15.4 to 29.7 °C in level III, respectively. The simulation results of operational air-conditioning energy consumption shows that the application of DST could save up to 65.5% of energy consumption compared with the traditional fixed setting temperature (FST), and the operational energy consumption decreased by 59.1% due to the application of level-III DST compared with level-I DST. Therefore, the DST proposed in this paper has significant energy saving potential while meeting the thermal comfort requirements.
