- Project to practically test and develop novel approaches to domestic retrofit
- House types to be retrofitted based on the findings of previous ETI research
- Project strengthens ETI’s growing capability in creating future-proof and economic local energy solutions across the UK
The aim of the project was to validate the cost, time and energy effectiveness of domestic retrofit activity across different house types, using an approach that could be employed to improve the energy efficiency of the vast majority of the existing 26 million homes in the UK which will still be in existence by 2050.
The novel, mass-scale retrofit approach tested was first developed in a deskbased ETI project “Optimising Thermal Efficiency of Existing Housing” completed in 2012, as part of the ETI Buildings programme.
The £541k project retrofitted five types of domestic property, identified and prioritised in the earlier ETI project.
- A pre-1919 mid-terrace house.
- A pre-1919 detached house.
- A 1919-44 semi-detached house.
- A 1945-64 semi-detached house.
- A post 1980 semi-detached house.
