Abstract
Climate change causes more frequent and severe heatwaves in temperate regions, posing a grave risk of heat exposure to dwellings. To address this, the United Kingdom government recently implemented regulations to mitigate overheating in English and Welsh homes. Approved Document O (ADO), as its accompanying technical guidance, recommends a modelling approach to demonstrating regulatory compliance for summertime thermal comfort, which is based on the Technical Memorandum 59 (TM59) methodology with modifications to the standardised window control behaviours. Previous studies have highlighted adaptive ventilation as a crucial measure to enhance heat resilience of future homes; however, the impact of such modifications on overheating prediction has not been quantitatively discussed, particularly in consideration of climate uncertainty. This paper aims to investigate the implications of the tailored window control rulesets in ADO on heat resilience evaluation for future homes under uncertain climatic conditions. Results suggest a statistically significant difference (p < 0.001) in overheating assessment results between TM59 and ADO, with the greatest effect observed on the expected overheating risk in nocturnal bedrooms. Quantitative evidence also reveals the critical role of nighttime ventilation in enhancing thermal comfort in future summers regarding both effectiveness and robustness.
