The first event in our Bitesize Webinar series.
About the tool
The new tool responds to demand from designers, housing associations, environmental health officers, and other parties concerned with overheating risks in the existing housing stock, which are likely to increase further due to climate change and higher temperatures.
This tool is intended for use at the early stages of residential retrofit projects, or on existing homes, in order to identify key factors contributing to overheating risk and possible mitigation measures. It is applicable to existing homes, retrofits, and conversions of non-domestic buildings to residential accommodation.
The tool and guidance are meant to be easy to use by non-specialists to inform early-stage big impact decisions. They promote holistic consideration of overheating risk together with the site context and linked design issues such as ventilation and noise. The potential impacts of energy efficiency measures through retrofit are included, but the tool also highlights the important opportunities for retrofit to contribute not only to overheating risk mitigation, but also improvements in air quality and energy efficiency.
This launch is a beta version, and the team will look to produce a revised version in early Autumn 2022. Please get in touch if you would like to provide feedback or trial this version on a project and inform the revision.

The project has been co-funded by the National Energy Foundation, and the BEIS funded REFINE project on radical decarbonisation of social housing through whole house energy retrofits.
The REFINE project is one of the Social Housing Decarbonisation Fund Demonstrators led by Warwick District Council and Oxford Brookes University with Enhabit/QODA Consulting and Sarah Wigglesworth Architects.
We would like to thank the following steering group members for their input during the project:
- Hayley Chivers, Sarah Wigglesworth Architects

The fourth meeting of the Pathfinder Network of Housing Associations. This is available to Pathfinder members only.
Committee report regarding a proposal in Cambridge of over 100 units.
Deemed of interest to the Vanguard group that includes a new planning condition on futureproofing homes for air source heat pumps. Condition 14 on page 63 of the report.
Urgent action to create sustainable city regions is essential to support sustainable, zero-carbon living and to tackle the climate and ecological emergency. Using inspirational case studies from leading city regions from around the world, this session will enable policy makers, community groups and development professionals to learn from City leaders who have helped to create exemplar built-environment projects, explaining:
- How city and region-wide initiatives can be used to create clean energy, and to help people use resources sustainably
- How barriers to creating a zero-carbon built environment, in development and operation, can be overcome,
- How community engagement can be enhanced to create sustainable cities and regions that work for everyone,
- How regional government, communities, and the built environment sector can work together to unlock sustainable living at scale,
- How to deliver a zero-carbon region in practice.

“Every Londoner should have access to a well-designed, safe, good quality home they can afford. This should be a right, not the preserve of the rich. Yet, too many Londoners continue to face inadequate housing options. COVID-19 has shone a fresh light on housing inequalities across the country, including in our capital city. The impact of this health crisis has been worsened by the existing housing crisis, with many confined to unsuitable accommodation.”

On November 4th 2021 Good Homes Alliance, alongside Bioregional and the Passivhaus Trust, hosted an event as part of the COP26 Built Environment Virtual Pavilion titled ‘Sustainable city-regions – how can we enable zero-carbon living at scale?’.
The below video is a short set of case studies from GHA members profiling the Oxford-Cambridge region. It featured as part of the wider event to generate debate on enabling zero-carbon living at scale, with the following objectives:
- To present inspirational case studies that provide solutions to a target audience of developers, policymakers, planners, and architects.
- To demonstrate how different approaches have delivered sustainability at scale for communities, cities, and regions across the world.
- To focus on energy issues, but also draw together a range of macro issues across a progressive sustainable built environment.
The video features:
- Hannah Scott, Bioregional
- Emma Davies, Greater Cambridge Shared Planning
- Tom Dollard, Pollard Thomas Edwards
The full event will be available on-demand in the near future.
Our Annual General Meeting was held online on Wednesday 27th October, 10:00-11:30 as we reflected on another vital year of climate action and look ahead to 2022.
The guide is useful for architects, engineers, Local Authorities, social landlords, energy professionals, contractors and clients looking for guidance about best practice retrofit.
It is widely accepted that retrofitting our existing buildings is absolutely critical if we are to achieve Net Zero. Around 18% of our annual national CO2e emissions come from existing homes – homes that will still be standing in 2050. 80% of 2050’s homes have already been built. It is also widely acknowledged that the retrofit challenge is monumental. Over one million homes every year for the next 30 years will need to be retrofitted. We cannot afford to retrofit them twice. But if we retrofit them well, we can enjoy many environmental, social and economic benefits.
This guide sets out what good retrofit looks like for existing homes. We target energy consumption reductions of 60-80% for the average UK home. This is achievable through a whole house approach upgrading the building fabric, incorporating energy efficiency measures, improving ventilation and fitting heat pumps. These targets have been determined through practical experience and understanding of what measures are realistically achievable. They are also informed by a national housing stock model to examine issues such as renewable energy provision and grid capacity. The guide also points out the potential risks of poor retrofit and advises on how to deliver efficient, resilient and healthy homes.
Quick start guide
The guide provides a quickstart guide to retrofit as well as typical house archetype examples for four primary housing types: semi-detached, detached, mid-terrace and a flat. Click on the pages below for the quickstart guide and typical house archetype examples.
