Overheating of building interior spaces as may arise from climate change and extreme heat events has been**identified as a major concern to the comfort and health of building occupants particularly of the vulnerable**people such as the elderly, children, the physically challenged or the sick. To ensure the resiliency of Canadian**buildings against overheating, and protect Canadians' health from a changing climate, the proposed research**focuses on assessing summertime overheating risks during heat waves in buildings housing vulnerable**populations through field measurements under the current climate, and providing mitigation solutions using**validated 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 be**monitored to assess risks of summertime overheating. 2). Simulations: Development of urban-scale**microclimate model and building-scale overheating model. The urban-scale model will be to simulate the**surrounding microclimate effects on specific buildings to be applied to detailed whole building simulations to**predict indoor thermal conditions under extreme heat events. 3). Mitigations: Development of mitigation**strategies 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 "Climate**Resilience Buildings and Core Public Infrastructure" program to develop guidelines and changes to building**codes 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 and**design guidelines for assessing and mitigating summertime overheating; 2). Support for the development of**climate adaptive building codes and standards; 3). Information necessary to municipal and provincial heath**authorities to help mitigate the effects of overheating in buildings, and 4). Training the next generation HQPs**ready for solving climate change related building design issues.

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的舒适和健康的主要问题，特别是弱势群体，如老人，儿童，身体残疾者或病人。为了确保加拿大 ** 建筑物抵御过热的弹性，并保护加拿大人的健康免受气候变化的影响，拟议的研究 ** 侧重于评估夏季热浪期间脆弱 ** 人群的建筑物过热风险，通过当前气候下的实地测量，并在预测的未来气候下使用 ** 验证的计算机模型提供缓解解决方案。研究活动安排如下：（1）。**现场监测：将 ** 监测11个选定建筑物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：城市尺度小气候模型和建筑物尺度过热模型的开发。城市规模的模型将模拟特定建筑物周围小气候的影响，并将其应用于详细的整个建筑物模拟，以预测极端高温事件下的室内热条件。3）。缓解措施：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。4）。指导原则：制定设计指南，以支持“气候适应性建筑和核心公共基础设施”计划下正在进行的NRC项目，为商业和住宅建筑的气候适应性设计制定指导方针和修改建筑规范。通过与NRC、**ECCC和HC的密切合作，该项目将产生重大成果，包括1）。预测计算机模型和 ** 评估和减轻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）。向省市卫生 ** 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。
