Good Homes Alliance is delighted to launch the final 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 tool and guidance could not come at a better time. Not only has the new Approved Document Part O come into force, UK temperatures topped 40c for the first time in recorded history.

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.
