SAP Calculations for New Build Dwellings (Approved Document L Compliance)

Encon Associates provide SAP Calculations for New Build Dwellings which may be required as part of planning applications or conditions of planning consent.

If you are building a new dwelling or an entire residential estate then you will need to comply with Planning and Building Regulation requirements for energy.

SAP calculations are required for all new build dwellings in order to provide an EPC (Energy Performance Certificates) for Building Control compliance.

What is SAP for New Build Dwellings?

SAP (Standard Assessment Procedure) is a licensed assessment tool carried out by accredited energy assessors to provide EPC’s (Energy Performance Certificates) and further documentation required for your local building control body for the overall sign off of the process.

SAP is used to calculate the Dwelling Emission Rate (DER) and the Dwelling Fabric Energy Efficiency (DFEE), both of which are benchmarked against the current standards set out in Approved Document Part L. To reach compliance those benchmarks need to be bettered or equalled. This results in an energy efficient home that will mean lower bills for the homeowners.

Approved Document L: Volume 1 2021 saw the introduction of Dwelling Primary Energy Rating (DPER) which calculates the regulated energy use of the dwelling. Once again, this is benchmarked against standards set out in Approved Document L and to reach compliance those benchmarks need to be bettered or equalled.

Each new home built to this standard is a massive step towards the UK Government’s net zero target.
