We collaborated with CIBSE, Elementa, WSP, UCL, Clarion Housing Group and Etude to publish a report on the future of SAP. The work makes recommendations on improving SAP and RdSAP so they are fit for net zero. The report was commissioned by the Department for Business, Energy and Industrial Strategy.

Standard Assessment Procedure (SAP) calculations are primarily required to demonstrate compliance with Part L of the Building Regulations for new dwellings and refurbishment of existing dwellings. It is the calculation methodology used to estimate and regulate the energy and carbon performance of new homes and the existing housing stock across the United Kingdom, from small works to large new developments. It is a central tool for those developing, implementing and tracking policies on energy, fuel poverty and carbon emissions and is being used by the whole building industry.

The team has worked over the last year on a report that summarises the issues that should be addressed in the next version of SAP to make it the best possible methodology by 2023-2024. These include current trends affecting housing, the energy system, technologies and innovations such as performance testing and verification.
