People living in social housing spend 17 % more time indoors compared to the general population. However, these dwellings often experience high indoor temperatures, significantly affecting households, particularly older people, who are more vulnerable to heat-related health issues. Economic limitations restrict these residents’ access to cooling systems, increasing their vulnerability during hot weather. The urban heat island (UHI) effect can increase urban overheating by 2.33 °C to 4.39 °C, impacting mortality rates. This study introduces a novel approach to investigate window opening behaviour, and its impact on thermal performance, and residents’ thermal perceptions in high-rise social housing apartment units during summer. Thermal conditions within each apartment were monitored over four weeks from December 2022 to March 2023. Residents’ perceptions were assessed using survey questionnaires that captured their thermal sensation, thermal satisfaction, and window operability behaviour. On average, the apartment units show risks of overheating (>26 °C) for approximately 25.74 % of the time. Notably, during these overheating periods, indoor temperatures were higher than the outdoor temperatures for 70.7 % of the time, primarily due to closed windows, suggesting that adequate ventilation can minimize overheating, maximize thermal comfort, improve residents’ resilience to the UHI effect, and help dissipate stored heat, thereby mitigating the UHI effect.

高层社会住房夏季过热时居住者开窗行为的影响



与普通人群相比,居住在社会住房中的人在室内花费的时间多 17%。然而,这些住宅经常经历较高的室内温度,严重影响家庭,尤其是老年人,他们更容易受到与高温相关的健康问题的影响。经济限制限制了这些居民使用冷却系统,增加了他们在炎热天气中的脆弱性。城市热岛效应 (UHI) 可使城市过热增加 2.33 °C 至 4.39 °C,从而影响死亡率。本研究引入了一种新方法来调查窗户打开行为,及其对夏季高层社会住房公寓单元的热性能和居民热感知的影响。从 2022 年 12 月到 2023 年 3 月,对每套公寓内的热状况进行了为期 4 周的监测。使用调查问卷评估居民的看法,这些问卷捕捉了他们的热感觉、热满意度和窗户可操作性行为。平均而言,公寓单元在大约 25.74% 的时间内表现出过热 (x3E26 °C) 的风险。值得注意的是,在这些过热期间,室内温度在 70.7% 的时间内高于室外温度,这主要是由于窗户关闭,这表明充足的通风可以最大限度地减少过热,最大限度地提高热舒适度,提高居民对 UHI 效应的适应能力,并有助于消散储存的热量,从而减轻 UHI 效应。
