As the high temperatures experienced during the summer of 2018 may become commonplace by 2050, adaptation to higher indoor temperatures while minimising the need for mechanical cooling is required. A thorough understanding of the factors that influence indoor temperatures can enable the design of healthier and safer dwellings under a warming climate. The aim of this paper is to provide further insight into the topic of indoor overheating through the analysis of the largest recent sample of English dwellings, the 2011 Energy Follow-Up Survey, comprised of 823 dwellings. Following the pre-processing stage, the indoor overheating risk of 795 living rooms and 799 bedrooms was quantified using the criteria defined within CIBSE's Technical Memorandum 59. Approximately 2.5% of the dwellings were found to exceed Criterion 1, with this figure approaching 26% when Criterion 2 was considered. Subsequently, the indoor temperatures were standardised against external weather conditions and the correlation of 11 dwelling and 9 household characteristics was examined. Factors such as the main heating system, tenure and occupant vulnerability were all found to have a statistically significant association with the indoor temperatures. Further analysis revealed multiple correlations between household and dwelling characteristics, highlighting the complexity of the indoor overheating problem. : By applying the criteria in CIBSE's TM59, 26% of the dwellings monitored during the 2011 Energy Follow-Up Survey were found to overheat. Since 2011 was a cool summer and future temperatures are expected to be warmer, even more dwellings are expected to fail these criteria in the future. Multiple dwelling and household characteristics were associated with higher indoor temperatures, including: dwellings with a SAP rating > 70, more recently built and with communal heating. Thus, it is crucial to consider indoor overheating risk at the building design or refurbishment stage to prevent the possible consequences of uncomfortably high indoor temperatures.
鉴于2018年夏季经历的高温到2050年可能会变得司空见惯,因此需要在尽量减少机械制冷需求的同时适应更高的室内温度。深入了解影响室内温度的因素有助于在气候变暖的情况下设计出更健康、更安全的住宅。本文旨在通过分析近期规模最大的英国住宅样本——2011年能源跟踪调查(涵盖823套住宅),进一步深入探讨室内过热这一主题。在预处理阶段之后,根据英国特许建造服务工程师学会(CIBSE)技术备忘录59中定义的标准,对795间客厅和799间卧室的室内过热风险进行了量化。结果发现,约2.5%的住宅超过了标准1,而考虑标准2时,这一数字接近26%。随后,根据外部天气条件对室内温度进行了标准化处理,并研究了11个住宅特征和9个家庭特征之间的相关性。结果发现,诸如主要供暖系统、房屋保有 tenure 和居住者易受伤害性等因素都与室内温度存在统计学上的显著关联。进一步分析揭示了家庭和住宅特征之间的多重相关性,凸显了室内过热问题的复杂性。:通过应用CIBSE的TM59中的标准,发现在2011年能源跟踪调查期间监测的住宅中有26%过热。由于2011年是凉爽的夏季,预计未来气温会更高,预计未来会有更多住宅不符合这些标准。多种住宅和家庭特征与较高的室内温度相关,包括:标准评估程序(SAP)评级>70的住宅、新建住宅和采用集中供暖的住宅。因此,在建筑设计或翻新阶段考虑室内过热风险至关重要,以防止室内温度过高带来的不适后果。
