||The aim of the project is to validate the cost, time and energy effectiveness of domestic retrofit 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 being 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 20-month long, £475,000 project will retrofit five types of domestic property, identified and prioritised in the earlier ETI project
Through its Optimising Thermal Efficiency of Existing Housing Project, the ETI developed a theoretical delivery mechanism for retrofitting the UK domestic housing stock at a sufficiently high rate to impact climate change targets, this was described as “the ETI Approach”. This document describes the methodology for implementing the ETI Approach on a house by house basis, considering
- the consumer,
- the solutions implemented
- the delivery mechanism itself and
- the potential business opportunities.
The ETI Approach was subsequently subjected to testing, evaluation and improvement via the ETI’s “Domestic Retrofit Demonstration Project”.
