Abstract

Summer 2022 was the joint hottest on record in England, with outdoor temperatures >40 C and five separate Level 3 Heat Health Alerts. During the heat periods excess deaths were 6.2% above the five-year average, with older people being most vulnerable. This paper presents research gathered from 41 care homes across England during summer 2022. Longitudinal monitoring of indoor and outdoor air temperature and relative humidity conducted in multiple locations within each care home allowed investigation of how building characteristics affected propensity for overheating. Spikes in temperature exceeded 40 C within three care homes and 35 C within 14 care homes. Mean temperatures in London care homes were nearly 2 C warmer than those elsewhere. Upper-floor rooms were significantly warmer than ground floor rooms, and urban/suburban care homes significantly warmer than rural care homes. Other characteristics (building age, size, room orientation) showed much less significant differences in temperature distributions between groups. The use of CIBSE overheating metrics (Guide A, TM52 and TM59) revealed endemic overheating across the care homes. This study has identified some differences between rooms/care home types that could help inform the future design and operation of care homes to protect against the negative consequences of overheating.
