人类大部分时间都在密闭空间中度过,因此主要暴露在室内气候的直接影响下。2013年和2014年夏季,在柏林(德国)的31个房间(8栋建筑)中获得了通用热气候指数(UTCI)。室内UTCI的确定从测量的空气温度和相对湿度和平均辐射温度和空气流速的数据,这是测量或建模。相关的室外UTCI是通过立面测量的空气温度和相对湿度,模拟平均辐射温度,从中央气象站的风数据。结果表明,所有的房间经历了热应力根据UTCI水平,特别是在热浪。室内UTCI在城市内变化高达6.6 K,在建筑物内变化高达7 K。白天或夜间的热应激发生在所有天数的35%。通过比较白天和夜间的热负荷,我们确定了夜间强热应力的最大值高于32 °C阈值。室外UTCI的外墙测量的基础上提供了室内UTCI的变化比中央气象站没有更好的解释。相比之下,我们发现室外空气温度和室内空气温度的关系更强。建筑物的特性,如楼层或窗面积,对室内热应力的影响不明显。我们的结论是,室内热应力是一个主要的危害,并需要更多的努力,了解原因,并制定有效的对策。
Humans spend most of their time in confined spaces and are hence primarily exposed to the direct influence of indoor climate. The Universal Thermal Climate Index (UTCI) was obtained in 31 rooms (eight buildings) in Berlin, Germany, during summer 2013 and 2014. The indoor UTCI was determined from measurements of both air temperature and relative humidity and from data of mean radiant temperature and air velocity, which were either measured or modeled. The associated outdoor UTCI was obtained through facade measurements of air temperature and relative humidity, simulation of mean radiant temperature, and wind data from a central weather station. The results show that all rooms experienced heat stress according to UTCI levels, especially during heat waves. Indoor UTCI varied up to 6.6 K within the city and up to 7 K within building. Heat stress either during day or at night occurred on 35 % of all days. By comparing the day and night thermal loads, we identified maximum values above the 32 °C threshold for strong heat stress during the nighttime. Outdoor UTCI based on facade measurements provided no better explanation of indoor UTCI variability than the central weather station. In contrast, we found a stronger relationship of outdoor air temperature and indoor air temperature. Building characteristics, such as the floor level or window area, influenced indoor heat stress ambiguously. We conclude that indoor heat stress is a major hazard, and more effort toward understanding the causes and creating effective countermeasures is needed.
