The Simplified Building Energy Model (SBEM) calculates the monthly carbon dioxide emissions and energy used by a building given its construction, geometry, use, lighting equipment and HVAC. SBEM ratings are scored from a scale of 1 to 100, with 1 being the worst and 100 being a zero usage of energy.

The SBEM calculations produce a BRUKL certificate which gives a rating for the building in question. If the BRUKL shows a pass then the project passes Building Regulations Part L. SBEM calculations and the requirements vary depending on whether it is a new build, extension or a refurbishment.

When do I need a SBEM Calculation?

They are design calculations that are required when you are refurbishing, building or extending a commercial premises.

SBEM calculation is required in order to comply with Building Regulations Part L1A & B and it is necessary to have SBEM calculations carried out on non-domestic construction projects. The SBEM calculations produce an SBEM report certificate which shows the SBEM rating for the building in question. If the SBEM report certificate shows a pass then the project passes Building Regulations Part L1B. SBEM calculations and the requirements of the SBEM report vary depending on whether it is a new build, extension or a refurbishment.

New build SBEM calculations work out the target emission rating (TER) followed by the building emission rating (BER). The BER must be equal to or less than the TER in order for the SBEM rating to show a pass on the SBEM report certificate.
