摘要

充足的睡眠对人类健康和幸福至关重要,夜间温度升高会降低睡眠质量。气候温和的欧洲国家使用25°C至28°C之间的温度阈值来识别过热的房屋。目前英国卧室的温度门槛是26°C,这是根据一项45年前的小型研究得出的。一项广泛的文献综述表明,使用现代夏季床上用品和床上用品,可以轻松调节身体覆盖范围,可以实现夜间卧室温度高达约29°C的热舒适。在英国有史以来最热的2018年夏天,591间卧室的温度被重新分析。将替代标准产生的夜间过热的发生率与已建立的适应性过热标准产生的发生率进行比较。对不同住宅和家庭特征的房屋进行了比较。最后,根据夜间卧室平均温度提出了一个新的过热标准,根据标准的应用,阈值在26°C到29°C之间。允许超过所选阈值的时间限于5月至9月之间的7个晚上。采用27°C和28°C的阈值,在2018年炎热的夏天,英国家庭中23%(550万)的主卧室被认为过热,远低于使用当前英国卧室标准获得的69%。无论所选择的阈值如何,根据住宅和家庭特征,过热患病率存在明显、一致和显著的差异。提出的新的过热标准适用于温带地区的无空调卧室。它试图在热卧室有空调的风险和温度不利于“晚上睡个好觉”的风险之间取得平衡。提出了一种新的过热标准来识别过热的卧室。它采用熟悉的温度阈值和允许超出的格式。当人们在没有空调的卧室里睡觉时,它适用于温带气候。该标准旨在帮助解释通过动态热模型和现有卧室的温度测量预测的夜间温度。适用于不同热敏度的人士、新屋的设计或现有屋的翻新。通过进一步的测试和改进,它为CIBSE指南a, TM59和其他指南中给出的现有英国卧室标准提供了可靠的替代品。因此,它可以为英国新住宅设计的新过热法规(Part O)提供支持。

An overheating criterion for bedrooms in temperate climates: Derivation and application
Adequate sleep is crucial to human health and well-being and elevated night-time temperatures can degrade sleep quality. European countries with temperate climates use temperature thresholds between 25°C and 28°C to identify homes that are overheated. The current UK bedroom threshold of 26°C, is based on one small study, which is now over 45 years old. An extensive literature review indicated that with modern summertime bedding and bedwear, which enables body coverage to be easily adjusted, thermal comfort can be achieved for night-time bedroom temperatures up to approximately 29°C. Temperatures measured in 591 bedrooms during England’s hottest ever summer, 2018, are re-analysed. The prevalences of night-time overheating generated by alternative criteria are compared with the prevalences generated by the established adaptive overheating criterion. Comparisons are made for homes with different dwelling and household characteristics. Finally, a new overheating criterion is proposed based on the mean night-time bedroom temperature, with thresholds between 26°C and 29°C depending on the application of the criterion. The allowable exceedance of the chosen threshold is limited to seven nights between May and September. Adopting thresholds of 27°C for vulnerable households and 28°C for others, 23% (5.5 million) of the main bedrooms in English homes were deemed to be overheated in the hot summer of 2018, far fewer than the 69% obtained using the current UK bedroom criterion. Irrespective of the threshold chosen, there were clear, consistent and significant differences in overheating prevalence depending on dwelling and household characteristics. The proposed new overheating criterion is applicable to unconditioned bedrooms in temperate regions. It seeks to strike a balance between the risk that hot bedrooms will be air-conditioned and the risk of temperatures detrimental to a “good nights’ sleep”. Practical Application A new overheating criterion is proposed to identify overheated bedrooms. It adopts the familiar format of a temperature threshold and an allowable exceedance. It is applicable in temperate climates when people are asleep in unconditioned bedrooms. The criterion is intended to aid the interpretation of night-time temperatures predicted by dynamic thermal models and temperature measurements in existing bedrooms. It is applicable to individuals of different heat sensitivity, the design of new homes or the refurbishment of existing homes. With further testing and refinement, it offers a credible replacement to the existing UK bedroom criterion given in CIBSE Guide A, TM59 and in other guides. It can thus underpin the new overheating regulations, Part O, for the design of new dwellings in England.
