SBEM Calculation Explained 

Low Carbon Energy Assessors (LCEA) Ltd provide Commercial Energy Performances Certificates, SBEM Calculations, Display Energy Certificates, M&E Quantity Surveying and Commercial Management Services throughout the whole of the UK.

What is a SBEM Calculation?

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 commercial premises.

SBEM calculation is required in order to comply with Building Regulations Part L1B 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.

Who needs a SBEM Calculation?

SBEM Calculations are required on buildings such as: –

• First fit out of a shell and core building
• Retail Shops
• Hotels
• Public Houses
• Offices
• Leisure centres
• Care homes
• Community buildings
• Schools
• Universities
• Warehouses

What does a SBEM Calculation provide?

They provide a carbon footprint of the proposed building (and are required by Building Regulations Part L) and tell you the energy cost and carbon emissions generated at the design stage of a project.

Very often changes will be made after the calculations in liaison with the architect, developer or client to ensure that the construction complies with the latest regulations. It is essential to engage with an accredited consultant before finalizing the design.

What is the connection between SBEM and an EPC?

Once the construction has been completed and all works have been carried out as per the sbem specifications, an energy performance certificate (EPC) is produced from sbem calculations.
