New Home Energy Model

by | Feb 26, 2024 | Regulation News | 0 comments

The government plans to replace the Standard Assessment Procedure (SAP) with a new Home Energy Model (HEM) as part of the upcoming Future Homes and Buildings Standards. This move aims to align the UK’s energy modelling standards with international best practices.

SAP currently calculates compliance with Part L of the Building Regulations in England, but it will give way to the HEM: Future Homes Standard (FHS) in 2025 to ensure dwellings meet the FHS requirements. While the model is still in development, the government is seeking industry input through consultations to shape its evolution.

Changes to the model ecosystem include adopting an open-source methodology, updating the database of product characteristics, and incorporating increased time resolution in the calculation methodology.
