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.
The tool builds upon the beta version which launched in March 2022, with new case studies and improved functionality. We would like to thank everyone who contributed with their comments and case studies.
