|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.
This is the call for proposals
The ETI wishes to demonstrate, test and improve the ETI Approach as the first step towards its planned large scale, integrated validation of a future smart energy system(the large scale validation is not in the scope of this RfP). This initial retrofit demonstration will be at a small scale across a number of existingproperty archetypes. The system solution to be developed by the Smart Systems and Heat programme is planned to be applicable to the UK as a whole, thereby presenting a significant market opportunity to Respondents.
The primary purpose of this RfP is for the ETI to acquire Datasets meeting the requirements set out. The Participant(s)will produce the Datasets during the three stages of the Project; before, during (installation of retrofits) and after the ETI Approach, to evaluate and improve its effectiveness
Using the Datasets acquired,Participant(s)shall fully evaluate and suggest improvements to the four key elements of the ETI Approach. In summary the data and evaluation will include:
The initial Datasets will cover 5 properties. It is acknowledged that the cost of these works will include physical retrofit and not just the cost of acquiring Datasets themselves.

- The deliveryof the ETI Approach;
- The consumeracceptabilityof the ETI Approach;
- The commercial viabilityof the ETI Approach.
