Standard Assessment Procedure (SAP 10.2): proposals for updates for heat networks
We're seeking views on proposals to improve the latest Standard Assessment Procedure (SAP) approach to assessing homes connected to heat networks that use recovered heat or Combined Heat and Power.
The Standard Assessment Procedure (SAP) is used to assess compliance with buildings regulations. It is also the methodology behind Energy Performance Certificates (EPCs), the rating system used to grade the energy efficiency of all homes in the UK.
This consultation sets out proposals to improve the approach of SAP 10 (the latest version of the Standard Assessment Procedure) to assessing:
- homes connected to heat networks that use recovered heat
- homes connected to heat networks using Combined Heat and Power (CHP)
The proposals intend to address the risk that SAP does not correctly model or reflect recovered heat sources for heat networks, and to better reflect the ability of heat networks using natural gas CHP units to displace more carbon intensive electricity generation.
The proposals support the development and delivery of heat networks as a key part of decarbonising heat as part of meeting 2050 net zero targets.
