Overview of SAP Assessments and EPC's

SAP Calculation and EPC

The design and build of residential buildings prompts the requirement for a SAP calculation.  Any changes to the building specification will impact the compliance with Part L Building Regulations.  Having an experienced SAP assessor involved is vitally important.

Do I need a SAP?

A SAP (Standard Assessment Procedure) is required for any new build residential construction and is a calculation for predicting how your design meets compliance with Government CO2 targets.  

From the design drawings (Architectural and Building Services) the SAP assessment is checked against Building Regulations (approved document Part L in England and Wales and Technical Handbook Section 6 in Scotland).  To show compliance on new builds, the Dwelling Emission Rate (DER) must be equal to or better (lower) than the Target Emission Rate (TER).  Some or all properties will need an air permeability rating (APR) this involves pressurising the unit to prove its air leakage rate, LEC can provide this ATTMA accredited test if required.

In addition to the Part L check the SAP is used to produce the final EPC (Energy Performance Certificate), which is required to market the sell or rent of the completed property.  If you are extending or renovating an existing dwelling then this may also require a SAP.
