Energy Performance Certificates

SAP & EPC for Residential Properties
A SAP (Standard Assessment Procedure) Calculation is required by Building Control for new builds and conversions to residential use.

SAP determines the energy efficiency and CO2 emission rate of a dwelling and demonstrates compliance with Parts L1A and L1B of the Building Regulations 2010.
It is a legal requirement that a Design Stage SAP calculation is completed before any construction begins. This is to ensure that any required changes are made to ensure the proposed dwelling satisfies the requirements.

NB: Completing the SAP calculation following completion of a building project could prove to be very costly.

SBEM & EPC for Commercial Properties
A SBEM (Simplified Building Energy Model) Calculation is required by Building Control for all Commercial New Build Projects, and Large Extensions.
SBEM determines the energy efficiency and CO2 emission rate of a commercial building and demonstrates compliance with Parts L2A and L2B of the Building Regulations 2010.

Once the construction is completed, a commercial EPC is produced to prove the building meets the stated energy efficiency requirement and to satisfy Building Control.
