As part of a three-year project – which is due to complete in time for the launch of the Future Homes Standard in 2025 – BRE will develop a new version of the Standard Assessment Procedure (SAP).
SAP is the government’s system for assessing and comparing the energy rating of residential dwellings.
It is a methodology is also used to create the information on Energy Performance Certificates (EPCs) and to show compliance with the energy conservation requirements of Building Regulations in the UK.
The project will see BRE lead a number of organisations and individuals in academia and industry to deliver a new methodology, known as ‘SAP 11’.
SAP 11 will be used by governments and industry to better measure and understand the energy performance of homes.
As part of SAP 11, BRE aims to undertake a ‘root and branch’ review of the existing methodology to create a new, better version.
It is hoped that this new version will help decarbonise the UK’s housing stock, taking into account technologies such as heat pumps, renewables, storage devices, and smart control features.
BRE’s methodology development will be guided by organisations and individuals within its steering group, who will either support the development of the method directly or be involved in the reviewing and validating process.
This includes Sustenic, Loughborough University, Kiwa, University of Strathclyde’s Energy Systems Research Unit, AECOM, and the Chartered Institution of Building Services Engineers (CIBSE).
The Future Homes Standard is a set of measures to be introduced on new homes built from 2025 to ensure they are fitted with low-carbon forms of heating, in line with the UK’s wider net-zero drive.
Commenting on the project, John Henderson, project director, BRE, said: “As the UK begins to escalate its net zero initiatives, SAP 11 will be instrumental in the effort to decarbonise the nation’s existing housing stock and ensure the use of low-carbon heating in new homes.
“As the new methodology will improve EPC accuracy, energy efficiency measurements will be more reliable than ever. Effective assessment of energy performance is going to be absolutely central to our progress towards net-zero.”
The Building Research Establishment (BRE) is a centre of building science in the United Kingdom, owned by charitable organisation the BRE Trust.
