项目摘要

Facing changing climates and more extreme weather events, there is increasing concern about the likelihood of increasing cooling energy demands, leading to occupants' indoor thermal discomfort, heat-related illness and even mortality. This is particularly important to urban dwellers, considering the compounding effects of ageing population, intensified urban heat islands, and increased frequency of urban heatwave episodes. Over the past two decades, many studies have investigated regional climate change impacts on building energy demands. However, few studies have been carried out which quantify the potential location-specific impacts on urban dwellings' thermal stress. Also, fewer efforts have been made in the large-scale urban context to deploy passive design strategies, adaptive and resilient to climate change according to quantified local demands. This has potential impacts for decarbonising policy in response to climate change factors and in improving urban dwellings' liveability. Successful dwelling stock management will therefore be enhanced by improving understanding of where and how energy demands can be reduced to lower thermal stress vulnerability for city dwellers.As a social scientific piece of work, my completed doctoral research formed a well-integrated methodology of how an engineering approach to quantifying climate change impacts on urban dwellings can influence and inform practice impact, such as building adaptation design resilient to climate change. This included identification of where action is required to minimize potential thermal risk and what, where and how adaptation and mitigation strategies could be developed for specific urban neighbourhoods. A key finding from my PhD thesis was that all urban dwellings are exposed to the likelihood of outdoor and building indoor thermal stress, but importantly the level of the risk varied by neighbourhood depending on occupants related socio-economic and demographic factors. Thus, building adaptation design strategies must be developed location-specifically, according to the quantified potential risk level for each neighbourhood identified.It is now my aim to consolidate this research with a programme of work focused on dissemination, engagement, and impact. This will be achieved via written pieces for a range of specific audiences in the form of journal papers, drawing on different dimensions of the research. I will also present my research at three major local and international conferences to broaden the academic reach of my research. Furthermore, during the fellowship I will be working alongside groups of people in Sheffield City Region with specific interests and needs, such as social housing and the older people who are vulnerable to changing climates. I will undergo collaborative engagement activities to address 'what are the specific needs of their community' in terms of improving their indoor thermal liveability through deploying adaptive passive design strategies resilient to climate change. These activities aim to build on my own relationship and networks with academia and housing policy and practice through utilising a well-known community platform (i.e. 'Live Projects' managed by Sheffield School of Architecture) and an existing multidisciplinary partnership between academia, housing policy and practice (i.e. the UK Collaborative Centre for Housing Evidence).

面对不断变化的气候和更多的极端天气事件，人们越来越担心制冷能源需求增加的可能性，导致居住者室内热不适，热相关疾病甚至死亡。考虑到人口老龄化、城市热岛加剧和城市热浪发生频率增加的综合影响，这对城市居民尤为重要。在过去的二十年里，许多研究调查了区域气候变化对建筑能源需求的影响。然而，很少有研究已经进行了量化的潜在位置特定的影响城市住宅的热应力。此外，在大规模城市背景下，根据量化的当地需求部署适应和抵御气候变化的被动设计战略的努力较少。这对应对气候变化因素的脱碳政策和改善城市住宅的宜居性具有潜在影响。因此，通过提高对在何处以及如何减少能源需求以降低城市居民热应力脆弱性的理解，成功的住宅存量管理将得到加强。作为一项社会科学工作，我完成的博士研究形成了一个完整的方法论，即量化气候变化对城市住宅影响的工程方法如何影响和告知实践影响，例如建造适应气候变化适应性设计。这包括确定需要在哪些地方采取行动以尽量减少潜在的热风险，以及可以在哪些地方以及如何为具体的城市居民区制定适应和缓解战略。我的博士论文的一个关键发现是，所有城市住宅都暴露在室外和建筑室内热应力的可能性下，但重要的是，风险水平因居住者相关的社会经济和人口因素而异。因此，建筑适应性设计策略必须根据每个社区的量化潜在风险水平来制定，现在我的目标是通过一个专注于传播，参与和影响的工作计划来巩固这项研究。这将通过以期刊论文的形式为一系列特定受众撰写文章来实现，借鉴研究的不同方面。我还将在三个主要的本地和国际会议上介绍我的研究，以扩大我的研究的学术范围。此外，在奖学金期间，我将与谢菲尔德城市地区有特定兴趣和需求的人群一起工作，例如社会住房和易受气候变化影响的老年人。我将参加合作参与活动，以解决“他们社区的具体需求”，通过部署适应气候变化的自适应被动设计策略来改善室内热宜居性。这些活动旨在通过利用知名的社区平台（即由谢菲尔德建筑学院管理的“Live Projects”）以及学术界、住房政策和实践之间现有的多学科合作伙伴关系（即英国住房证据合作中心），建立我与学术界和住房政策和实践的关系和网络。
