BEIS Demonstration of Energy Efficiency Potential (DEEP)

Investigating risk and performance of partial and whole house retrofits

This £2.7 million is project, funded by the Department for Business, Energy and Industrial Strategy and is one of the largest domestic retrofit projects to have ever been attempted in the UK.  The results on risk and performance will guide future retrofit policy.  It will critique thermal models including dynamic simulation models (DSM) and the Government’s Standard Assessment Procedure (SAP), as well as hygrothermal simulations that are currently used to predict performance and risk, and use building performance evaluation (BPE) field trials, including the Leeds Beckett Coheating Test and novel assessment methods such as the QUB and Pulse testing equipment, to measure and explore how single measure and whole house retrofit impact homes.  The project will involve undertaking 150 surveys to explore why retrofit performance often deteriorates and will also undertake 31 retrofits on case study homes in the North of England. The project is a consortium with the University of Salford who will investigate retrofits in their energy house facility; Loughborough University, who will undertake hygrothermal investigations into retrofits in their laboratory as well as; Lucideon Ltd who will evaluate the properties of common UK building materials in their materials testing facility.
