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导致建筑物内部空间过热，这已被确定为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**侧重于通过在当前气候下的实地测量，评估易受伤害**人群居住的建筑物在热浪期间的夏季过热风险，并在预测的未来气候下使用**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：对选定的11栋建筑进行室内热条件和室外气候条件的**监测，评估夏季过热风险。2）. 模拟：开发城市尺度的微气候模型和建筑尺度的过热模型。城市尺度的模型将模拟周围的小气候对特定建筑的影响，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）. 减缓：考虑到加拿大不同气候带的城市尺度小气候和气候变化，制定减缓战略**。**4)。指南：制定设计指南，以支持NRC在“气候适应性建筑和核心公共基础设施”计划下正在进行的项目，为商业和住宅建筑的气候适应性设计制定指南和修改建筑规范。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)。预测计算机模型和设计指南，以评估和减轻夏季过热；2）. 支持气候适应性建筑规范和标准的制定；3）. 市和省卫生**当局为帮助减轻建筑物过热的影响所必需的信息；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 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.
