SBEM Calculations

Part L2a of the building regulations require all new non-domestic buildings which is also often referred to as commercial buildings to prepare a SBEM calculation in order to demonstrate that the building’s energy emission rate (BER) is lower than a target emission rate (TER). The process involves a set of desktop calculations prepared using drawings and specifications. Part L2a requires that the SBEM calculation must been submitted to the building control officer prior to commencement of any works onsite.

​

Our experienced team of SBEM accredited energy assessors are able to work with you to ensure that your project not only passes the BER/TER requirement but does so in the most cost effective manner possible. Our approach for every project is to provide a bespoke solution customised for every client and its project. Our solutions have helped clients save many thousands of pounds which has forged long lasting relationships. 

Upon completion of the building the SBEM calculation is used to prepare the Energy Performance Certificate (EPC). Usually a site visit is required to gather photographic evidence of the building as built.

Additionally, upon completion we are able to undertake the Air Permeability Testing for your project too.
