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认为是影响建筑物居住者舒适度和健康的主要问题，特别是老年人、儿童、残疾人或病人等弱势群体。为了确保加拿大建筑物抵御过热的能力，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热浪期间脆弱人群居住的建筑物的夏季过热风险，并在预测的未来气候下使用经过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：对选定的11栋建筑的室内热状况和室外气候状况进行监测，评估夏季过热风险。 2）。模拟：开发城市规模微气候模型和建筑规模过热模型。城市规模模型将模拟周围微气候对特定建筑物的影响，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）。缓解措施：通过考虑加拿大不同气候带的城市规模微气候和气候变化来制定缓解策略。4)。指南：制定设计指南，以支持“气候适应力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力设计制定指南并修改建筑规范。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)。用于评估和缓解夏季过热的预测计算机模型和设计指南； 2）。支持制定气候适应性建筑规范和标准； 3）。市和省卫生当局帮助减轻建筑物过热影响所需的信息，以及 4)。培训下一代总部人员，为解决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.
