Scaling Up Retrofit 2050

Report published by the IET and Nottingham Trent University on the need for deep retrofit of our existing housing stock.

“Domestic energy consumption accounts for about 30% of the UK’s total energy budget, and 20% of UK greenhouse gas emissions. Reduction in carbon emissions from domestic properties is essential to achieve the goals of the 2008 Climate Change Act.
Over three-quarters of household energy demand is for space and hot water heating. We must decarbonise or reduce heating demand. Since 80% of the homes we will be living in by 2050 have already been built, a nationwide programme of deep retrofits and refurbishment of the existing stock is the only way to deliver the required carbon savings.
Deep retrofitting to 2050 standards is complex and costly but early pioneers are attempting this transformation. There are a number of cases across
Europe where retrofit development at scale has already been achieved or is being delivered, several of which are highlighted in section 4 of this report. This document focuses on how to scale up these attempts.”

Miller-Klein Associates were the principal investigators and authors of this report.
