Domestic EPCs
The calculation of the energy ratings on the Energy Performance Certificate (EPC) are based on the RDSAPv3 procedure, which is a simplified version of the SAP2005. SAP is short for Standard Assessment Procedure and RDSAP for Reduced Data SAP; both are derived from the UK Building Research Establishment's Domestic Energy Model (BREDEM), which was originally developed in the 1980s and also underlies the NHER Rating. EPCs have to be produced by Domestic Energy Assessors who are registered under an approved certification scheme.
