LETI publishes Climate Emergency Retrofit Guide
In October 2021, more than 100 construction professionals representing leading architecture and engineering firms, academia and NGOs joined together for the publication of the London Energy Transformation Initiative (LETI) Climate Emergency Retrofit Guide, which aims to provide a blueprint for how we can retrofit our homes to support the UK's net zero targets.
The publication provides guidance on how those targets can be achieved through energy efficiency measures and heat pumps. LETI defines retrofit specifications for four primary housing types (mid-terrace, semi-detached, detached and apartment) and provides advice on how to meet those specifications.
The Climate Emergency Retrofit Guide sets out what good retrofit looks like for existing homes. LETI defines space heating and energy use requirements – targeting a 60% to 80% reduction in total energy consumption for the average UK home. These targets have been determined through a combination of practical experience and understanding of what measures are realistically achievable, informed by a national housing stock model, to examine issues such as renewable energy provision and grid capacity, said LETI.
The guide points out the potential risks of poor retrofit and advises on how to deliver efficient, resilient and healthy homes. LETI stated that good retrofit can bring multiple environment, social and economic benefits but this requires a whole-house approach and a shift from fossil fuels to electricity for heating and hot water.
Antonia Khayatt from LETI said, "Retrofitting buildings to be more energy efficient doesn't just reduce carbon emissions and energy bills. It can improve comfort and health, create jobs and reduce fuel poverty. It can also reduce the demand on and costs to the UK's energy infrastructure. This guide explains these issues and shows how taking the LETI approach to retrofit will help us enjoy these broader benefits."
The cross-industry guide, published by LETI, is backed by professional institutions and organisations including the Royal Institute of British Architects (RIBA), the UK Green Building Council (UKGBC) and the Better Building Partnership (BBP). The guide is available to download for free.
