Assessment and mitigation of summertime overheating conditions in vulnerable buildings of urban agglomerations

气候变化和极端高温事件可能引起的建筑物内部空间过热已被确定为建筑物居住者，特别是老年人、儿童、残障人士或病人等弱势群体的舒适度和健康的主要关切。为了确保加拿大建筑对过热的弹性，并保护加拿大人的健康免受气候变化的影响，拟议的研究重点是通过当前气候下的现场测量来评估夏季热浪期间建筑中易受影响的人口过热的风险，并使用预测的未来气候下经过验证的计算机模型提供缓解方案。研究活动安排如下：1)现场监测：将监测11个选定建筑的室内热状况和外部气候条件，以评估夏季过热的风险。2)。模拟：城市尺度小气候模式和建筑尺度过热模式的发展。城市尺度模型将模拟特定建筑周围的小气候影响，并应用于详细的整个建筑模拟，以预测极端高温事件下的室内热状况。3)。缓解：通过考虑城市尺度的小气候和加拿大不同气候带的气候变化，制定缓解战略。准则：制定设计准则，以支持NRC正在进行的“气候适应性建筑和核心公共基础设施”计划下的项目，为商业和住宅建筑的气候弹性设计制定准则和更改建筑规范。在与NRC、ECCC和HC的密切合作下，该项目将产生重大成果，包括1)。预测计算机模型和评估和缓解夏季过热的设计指南；2)。支持制定适应气候变化的建筑规范和标准；3)向市级和省级卫生当局提供必要的信息，以帮助减轻建筑物过热的影响；以及4)。培训下一代HQP，为解决与气候变化相关的建筑设计问题做好准备。

Overheating of building interior spaces as may arise from climate change and extreme heat events has beenidentified as a major concern to the comfort and health of building occupants particularly of the vulnerablepeople such as the elderly, children, the physically challenged or the sick. To ensure the resiliency of Canadianbuildings against overheating, and protect Canadians' health from a changing climate, the proposed researchfocuses on assessing summertime overheating risks during heat waves in buildings housing vulnerablepopulations through field measurements under the current climate, and providing mitigation solutions usingvalidated computer models under predicted future climates. The research activities are organized as follows: 1).Field monitoring: Indoor thermal conditions of 11 selected buildings and exterior climatic conditions will bemonitored to assess risks of summertime overheating. 2). Simulations: Development of urban-scalemicroclimate model and building-scale overheating model. The urban-scale model will be to simulate thesurrounding microclimate effects on specific buildings to be applied to detailed whole building simulations topredict indoor thermal conditions under extreme heat events. 3). Mitigations: Development of mitigationstrategies by considering urban-scale microclimate and climate change for different Canadian climatic zones.4). Guidelines: Development of design guidelines to support the ongoing NRC projects under the "ClimateResilience Buildings and Core Public Infrastructure" program to develop guidelines and changes to buildingcodes for climate resilience design of commercial and residential buildings. In close collaborations with NRC,ECCC and HC, the project will produce significant outcomes including 1). Forecasting computer models anddesign guidelines for assessing and mitigating summertime overheating; 2). Support for the development ofclimate adaptive building codes and standards; 3). Information necessary to municipal and provincial heathauthorities to help mitigate the effects of overheating in buildings, and 4). Training the next generation HQPsready for solving climate change related building design issues.
