SAP Calculations (Standard Assessment Procedure) are the Government approved method of showing compliance with Part L of the Building Regulations. L1A is for new-build dwellings and L1B for refurbishments and conversions.

​

The EPC (Energy Performance Certificate) is the end result of this process, which shows the overall level achieved along with recommendations for where improvements could be made.

​

The calculation considers the building fabric, services and and renewable technology proposed, to make a prediction of the energy performance and Carbon emissions of the proposed dwelling (or refurbishment/conversion).

​

They are usually undertaken both at the design stage and post-construction, usually with minimal changes between the two.

​

It is important to ensure the proposed design and specification meets Building Regulations from the outset and so early involvement of the SAP assessor is crucial to avoid problems further into the build. It is no longer something that can be left as an afterthought.

​
