Last Thursday, LETI (London Energy Transformation Initiative) released the Climate Emergency Retrofit Guide, which provides clear energy use targets and guidance on energy efficiency measures and zero carbon heating.

The cross-industry guide is backed by the Royal Institute of British Architects (RIBA), the Passivhaus Trust, the Chartered Institution of Building Service Engineers (CIBSE), Architects Declare, the UK Green Building Council (UKGBC), the Association for Environment Conscious Building (AECB), Architects Climate Action Network (ACAN) and the Better Building Partnership (BBP). 

We're proud to have contributed to this important and timely guidance on retrofitting our homes to support the UK’s Net Zero targets. Defining targets for existing homes, the publication provides practical guidance on how to achieve them through energy efficiency measures and heat pumps. 

Four of our engineers contributed to the creation of the guide:

• Tom Greenhill, Senior Engineer
• Andrew Leiper, Net Zero Carbon Leader
• David Lam, Passivhaus Consultant
• Colin Darlington, Performance Spaces Leader

From being involved in the chapter discussions and giving simple recommendations that plumbers/electricians could make, to inputting into the risk and benefits workstream, to reviewing and commenting on the final draft, they volunteered alongside over a hundred leading architects, engineers and building professionals to bring the guide to life.

Here’s what they say:

“This LETI guidance is a great resource for anyone with an interest in reducing the impact of our existing buildings and helping to tackle the world's energy emissions.” – David Lam, Passivhaus Consultant at Max Fordham

 

“The guide provides much-needed, accessible information on what is required to reduce the environmental impact of existing dwellings in a considered and integrated way.” – Colin Darlington, Performance Spaces Leader and Senior Partner at Max Fordham
