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

This responds to demand from designers, housing associations, environmental health officers, and other parties concerned with overheating risk in the existing housing stock. The aim is to produce simple practical guidance to help identify and mitigate the risk of overheating on existing homes and retrofits, informing design options and mitigation measures.

The project is co-funded by the BEIS funded REFINE project on radical decarbonisation of social housing through whole house energy retrofits, and by the National Energy Foundation. The REFINE project is one of the Social Housing Decarbonisation Fund Demonstrators led by Warwick District Council and Oxford Brookes University with Enhabit and Sarah Wigglesworth Architects.

Ahead of the launch, lead author Julie Godefroy will be giving a sneak-peek of the new tool at our Futurebuild session on Tuesday 1st March, 14:15-15:00 at ExCel London (Keynote stage 1) – The net zero challenge for new homes. Please do join us!

For more information about the Overheating in Retrofit Homes project, please contact Julie Godefroy – or Susie Diamond –


The hour-long launch event will take place online on Thursday 17th March 2022, with talks from authors Julie Godefroy (Julie Godefroy Sustainability) and Susie Diamond (Inkling).
