PS22165 - Seeking 'whole house' decarbonisation solutions for Hard-to-Treat homes

***THIS IS NOT A CALL FOR COMPETITION**** This contract has been awarded.

Aims and Objectives of the Project

The Hard-to-Treat (HTT) homes research aims to create a definition of and understanding of the scope of HTT homes in the UK, to support the development of policies that will effectively enable retrofitting and decarbonisation of these homes. The objectives are as follows: • Identify the technical (including physical, material and technological), regulatory and social challenges to improving the energy performance and decarbonising HTT homes, taking account of spatial variability across the UK; • Document and review the evidence on existing approaches to retrofitting HTT homes - including reviewing international policies, considering the costs to implement retrofit upgrades and implications for future retrofit schemes; • Develop a framework/definition, which identifies a spectrum of technical, physical and material attributes that make a home HTT from a whole house retrofit perspective; • Identify potential data and/or sources of information that could be used to identify HTT homes for both energy efficiency and low carbon heating; • Review, compare and propose best-practice methods and approaches (e.g. data analytics) for identifying HTT homes.
