SBEM Calculations

What is a SBEM Calculation?

The SBEM calculates the monthly carbon dioxide emissions and energy used by a building given its construction, geometry, use, lighting equipment and HVAC.

Simplified Building Energy Model

SBEM calculations are like SAP calculations but are for non-domestic buildings.

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.

Emirates Cable Car

Emirates Cable Car runs between the Royal Docks and North Greenwich, taking 10 minutes. It was commissioned to coincide with London Olympics 2012.

EAL Consult was appointed to carry out the SBEM calculations for the north and south terminals in 2014.

When do I need an SBEM Calculation?

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

SBEM calculations are required in order to comply with Building Regulations Part L2. It is compulsory to have SBEM calculations carried out on non-domestic construction projects. The SBEM calculations produce an SBEM report certificate which shows the energy efficiency rating for the building in question. If the SBEM report certificate shows a pass then the project passes Building Regulations Part L2.

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:

  • Shops/offices
  • Hotels
  • Places of work like offices and warehouses
  • Leisure centres
  • Care homes
  • Community buildings

What does a SBEM Calculation provide?

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

Very often changes will be made after As Design 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.
