HEARTH Newsletter
Issue 2, May 2026
Welcome to the second newsletter of the HEARTH Hub on Net Zero, Health and Extreme Heat (www.hearth.ac.uk). Since the first edition in December 2025, the HEARTH Hub has continued to expand its network of researchers, stakeholders, policymakers, and industry and community partners.
In 2026, the HEARTH Hub has focused on strengthening stakeholder collaborations, delivering targeted workshops, securing ethics approval, and advancing case study recruitment and fieldwork preparation, including monitoring and surveys. Key progress includes the establishment of HEARTH-wide Working Groups, the development of building archetypes, the HEARTH Theory of Change, and ongoing modelling activities.
This edition highlights growing national and international engagement, contributions to policy and professional practice, meetings of the Working Groups, and stakeholder workshops.
Thank you for your continued interest in HEARTH.
Professor Rajat Gupta
Director of HEARTH
To enhance collaboration and expert oversight, the Hub has established formal working groups to align research priorities and co-design intervention strategies. These groups bring together academic partners, partner organisations and external stakeholders. The established working group include:
Care Settings Working Group (Chair: Professor Mike Davies)
Homes Working Group (Chair: Professor Rajat Gupta)
Hospitals Working Group (Chair: Professor Shakoor Hajat)
London Working Group (Chair: Professor Anna Mavrogianni).
On 24 March 2026 the inaugural meeting of the Care Settings Working Group (CSWG) was held. The first session introduced the working group and clarified its Terms of Reference and membership, reviewed the HEARTH Theory of Change for care settings, and provided an overview of ongoing projects, including ClimaCare, ARCADE, HEARTH, and THERM-UK.
The workshop also outlined planned research in care settings, ensuring alignment between current initiatives and future study objectives. Building on this progress, the first meetings for the Homes, Hospitals, and London Working Groups are scheduled to take place in spring and summer 2026, complemented by targeted stakeholder workshops to co-develop heat adaptation interventions and align fieldwork priorities across case study sites.

Researchers from the HEARTH Hub have actively shared their work at national and international forums, highlighting climate resilience, overheating risks, and the integration of health considerations into mainstream and older people housing, as well as urban environments. These activities contribute to scientific advancement and practical knowledge exchange, ensuring that research informs policy, professional practice, and future research agendas.
National and Regional Engagement
Significant visibility was achieved through invited keynotes, presentations, and stakeholder workshops at major events during the first quarter of 2026, focusing on practical applications and sector engagement:
Climate Adaptation in Wales (MACC Workshop)
On 5 March 2026, Professors Anna Mavrogianni and Rajat Gupta participated as expert panel members at the MACC workshop in Cardiff. The session facilitated the exchange of research on climate resilience and health, strengthening the Hub’s ties with adaptation networks across Wales.

London Climate Ready Partnership Forum (City Hall, London, 27 February 2026)
Professors Anna Mavrogianni and Rajat Gupta attended the London Climate Ready Partnership Forum on Tackling Heat Risks in London, where they introduced HEARTH, as well as the HEARTH London Working Group. They were joined by project team members from the Greater London Authority (GLA), Annette Figueiredo, Dr Emer O’Connell and Dr Jiayu Pan, and from UKHSA, Dr Ross Thompson, as shown in the photograph below.

National Housing Maintenance Forum (Stratford-upon-Avon, 20 January 2026)
Professor Rajat Gupta delivered a keynote to social housing providers, introducing HEARTH in the plenary session (Keeping Warm Homes Healthy: How to Avoid Unhealthy Retrofit). At the conference, HEARTH was exhibited by Dr Yuanhong Zhao through posters and flyers, including calls for participation. A number of social housing providers expressed interest in collaborating on the research.

Global Knowledge Exchange
HEARTH contributed to international research dialogues through a series of invited keynote presentations by Professor Shakoor Hajat (LSHTM), highlighting current priorities in climate and health research and strengthening international collaboration in environmental epidemiology:
University of Tokyo (27 January 2026): Keynote on “Current Climate and Health Research in the UK” as part of the Lecture Series in Global Health Policy.
Lecture Series in Global Health Policy University of Tokyo,
27 January 2026
Nagasaki University (30 January 2026): Keynote on “Current Climate and Health Research in the UK” within the Seminar Series.
Seoul National University (1 February 2026): Keynote at the Symposium for Environmental Epidemiology in East Asia, introducing HEARTH and engaging with leading scholars on air pollution, climate change, and future regional collaboration.
Accepted Research Papers
Peer-reviewed research from the Hub has been accepted for presentation at several major conferences throughout 2026, covering the breadth of the Hub’s interdisciplinary programme:
Geographic Information Science Research UK (GISRUK 2026) – Birmingham, 15–17 April 2026: Oral presentation on How Temperature Datasets Shape Spatial Heat Vulnerability: Observations versus Urban Climate Modelling.
Making Research Stronger Together: Public Health Research in Local Authorities London Conference – London, 06 May 2026: Abstract for the paper titled “A place-based approach towards understanding and improving heat resilience in older people housing” accepted for presentation.
European Geosciences Union (EGU 2026) General Assembly – Vienna, 3–8 May 2026: Oral presentation on humid heatwaves, their meteorological drivers, and associated impacts.
Policy and Stakeholder Engagement
The HEARTH Research Hub has strengthened influence through key appointments and contributions to national policy and professional standards. Engagement with regulatory bodies ensures that research outputs are translated into actionable guidance for a climate-resilient future.
Shaping National Standards (BSI PAS 20501)
In January 2026, Dr Hugh Waddington (LSHTM) represented the Hub in a scoping workshop for a new British Standards Institution (BSI) standard. The focus of this work is defining and measuring the human health benefits of net zero actions, ensuring that public health remains a central metric in future climate mitigation standards.

Co-designing Heat Adaptation for NHS (ARCHI Stakeholder Workshops)
Strategic leadership continued through the NIHR-funded ARCHI (Adaptation for Resilience and Equity in Communities and Health Infrastructure) project, co-developing heat adaptation interventions for NHS buildings in collaboration with HEARTH. This progressed through series of workshops in the first quarter of 2026:
19 January 2026: The first online workshop explored adaptation solutions for NHS buildings, bringing together researchers, NHS staff, and patients. Key insights included pilot study evidence showing external shading reduced indoor temperatures and proximity to nature was linked with shorter hospital stays.
ARCHI workshop, 19 January 2026
24 March 2026: This workshop focused on hospital estates, presenting evidence from environmental monitoring, thermal simulations, and hospital archetype modelling to support practical, scalable cooling solutions for hospital and care environments.
