摘要正如2003年欧洲热浪所表明的那样，家庭过热会导致大规模的死亡。随着气温和热浪频率预计将因气候变化而增加，预计此类事件将变得更加普遍。因此，调查建筑物过热的风险是了解问题规模和设计解决方案的关键。关于这个主题的大多数工作都是理论性的，并且基于可能会过热的轻质住宅。相比之下，这项研究收集了两年内脆弱和非脆弱的英国家庭的温度和空气质量数据，预计过热不会很常见。过热的情况被发现，特别是和不成比例地发生在有弱势居住者的家庭。由于所讨论的夏季并不极端，也没有长时间的热浪，这是一个重要而令人担忧的发现。脆弱的家庭也被发现有更差的室内空气质量。这表明，一些问题可以通过加强室内通风来解决。收集的热舒适调查数据也验证了欧洲自适应模型。结果表明，该模型低估了温暖条件下的不适，对脆弱和非脆弱的家园都有影响。
ABSTRACT As the 2003 European heatwave demonstrated, overheating in homes can cause wide-scale fatalities. With temperatures and heatwave frequency predicted to increase due to climate change, such events can be expected to become more common. Thus, investigating the risk of overheating in buildings is key to understanding the scale of the problem and in designing solutions. Most work on this topic has been theoretical and based on lightweight dwellings that might be expected to overheat. By contrast, this study collects temperature and air quality data over two years for vulnerable and non-vulnerable UK homes where overheating would not be expected to be common. Overheating was found to occur, particularly and disproportionately in households with vulnerable occupants. As the summers in question were not extreme and contained no prolonged heatwaves, this is a significant and worrying finding. The vulnerable homes were also found to have worse indoor air quality. This suggests that some of the problem might be solved by enhancing indoor ventilation. The collected thermal comfort survey data were also validated against the European adaptive model. Results suggest that the model underestimates discomfort in warm conditions, having implications for both vulnerable and non-vulnerable homes.
