Webinar: Overheating risk tool for retrofit – Launch

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.

Climate Emergency Retrofit Guide

LETI’s Climate Emergency Retrofit Guide shows how we can retrofit our homes to make them fit for the future and support the UK’s Net Zero targets.  We define energy use targets for existing homes and provide practical guidance on how to achieve them.  

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.
