New Build EPC
The new build EPC (Energy Perforamce Certificate) is a mandatory certificate which summarizes the SAP assessment and is used when marketing the property for sale.
Building Control will not issue a completion certificate until a valid new build EPC has been produced by a certified Energy Assessor.
Standard Assessment Procedure (SAP) calculations are a mandatory requirement for any new build dwelling. SAP is used to show compliance with Part L of the Building Regulations and is applied at the design stage of the build process and is submitted to Building Control.
SAP calculates the energy cost and carbon emissions generated to heat, light, ventilate and provide hot water to a building. A SAP calculation at the design stage, produces a Projected Energy Assessment (PEA) which details how much energy a new home will use. This is translated into a more user-friendly Energy Performance Certificate (EPC) once the building has been constructed.
