Thermal Stress Vulnerability and Resilience: Housing Stock Transformation fit for an Ageing Society in Future Climate

Lead Research Organisation: University of Sheffield
Department Name: Architectural Studies

Abstract

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).

Description The aim of this postdoctoral fellowship is a successful transition of my PhD study (multiscale indoor thermal stress modelling for general population) into the specific older populations vulnerable to changing climate to achieve care home stock transformation fit for the future. This requires to deepen my understanding of indoor thermal environment for older populations living in care home (indoors) where they spend majority of time. Achieving this aim has been supported by fulfilling the following achievements:

1. Publication
• Yi, C., Childs, C., Peng, C. and Robinson, D. Thermal comfort modelling of older people living in care homes: An evaluation of heat balance, adaptive comfort, and thermographic methods. Building and Environment, 207 (2022), DOI:10.1016/j.buildenv.2021.108550

2. Interdisciplinary research experience, working with public health and physiological experts from Sheffield Hallam University and Derbyshire Healthcare NHS Foundation Trust.

3. Training and personal skill development, including teaching skills (Sheffield Teaching Assistant), data analytic skills and Python programming for machine learning.

4. Success in funding applications and postdoctoral development activities
• Co-producing an environmental performance guidelines framework for care homes fit for the future, £16.5k, funded by Higher Education Innovation Fund (HEIF) 2021-22, 01 January to 31 July in 2022.
• Observing individual differences to co-produce hybrid working decisions towards designing Net Zero strategies, Shortlisted in UKRI C-Dice Sandpit2 in Nov 2021 and invited to submit a full proposal to win £30k by Jan 2022.
• Appointed Supervisor for four MSc students and 2nd Supervisor for two PhD students at the Sheffield School of Architecture.
Exploitation Route The care home study performed under this fellowship can be considered a 'learning' in understanding the conditions of the built environment that has been little studied for those being cared. As a result, the published journal article is expected to be used to drive forward our understanding of thermal comfort and ways of achieving comfort for those at risk in the care home environment, and thus to support the evidence-based formulation of guidelines for the indoor environmental management of care homes.

Description The finding of the care home thermal comfort modelling study has had a 'pathway' impact to make a collaborative knowledge exchange project working with care home stakeholders, which aims to deliver a 'long-term' impact of improved environmental design for all with effective infections control and net-zero CO2 emissions by 2050, whilst safeguarding the daily opportunities of residents' social contact interaction as well as the well-being of carers.

PI Contribution We are a research team with interests in indoor environments and the corresponding health outcomes for specific older populations living in care homes, identified as one of population groups most vulnerable outbreaks of infectious diseases and to physiological stresses arising from discomforting indoor conditions. As a principle investigator of the ESRC Postdoctoral fellowship, I have led the care home thermal comfort modelling study working with partners listed. Through this collaboration, we are currently performing a knowledge exchange project as a follow-on study, aiming to co-producing an environmental performance guidelines framework for care homes fit for the future.
Collaborator Contribution The partners have made significant contributions to my successful postdoctoral fellowship, as mentors through providing careful guidance on research design and methodological development in care home indoor environment, which has little studied yet.
