Public consultation on proposals to amend the Standard Assessment Procedure (SAP)

BEIS launched a consultation on the 16th November 2016 on the Standard Assessment Procedure (SAP), the calculation used in housebuilding to demonstrate compliance with building regulations and to derive Energy Performance Certificates (EPCs), through Reduced Data SAP (RdSAP).

Housebuilders must achieve a Dwelling Emission Rate (DER) of carbon dioxide calculated by SAP that is lower than a Target Emissions Rate (TER).  The TER is also calculated by SAP for the same shape of house based on a package of measures and U values (the notional house).
