Overheating in Retrofit and Existing Homes – Tool and Guidance

Following a well-received overheating risk tool and guidance for new build homes, Good Homes Alliance is delighted to launch the beta version of a new tool and accompanying guidance developed for existing homes and retrofit schemes.

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 work has been led by Julie Godefroy of Julie Godefroy Sustainability, with support from Susie Diamond of Inkling LLP.

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:
