SBEM calculations

SBEM calculations are in essence an EPC before it has been processed. At the design stage the building, contractor, architect, foreman will present us with the plans and ask whether it will be sufficient to comply with the latest building regulations and have to be produced for all new build, conversions and extended premises and commercial properties in relation to the building's energy efficiency and C02 emissions.

If any areas of the building require adjustment to improve the energy efficiency the assesor will advise the client they will need to for example, use a condening 'A' boiler or use T5 lamps, or improve the insulation values.

Energy Assessors London provide SBEM calculations (New Build Certificates) and EPCS upon completion.

SBEM  known as  simplified building energy model, provides an analysis of the energy consumption of a building. The SBEM calculates the monthly carbon dioxide emitted 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.

SBEM Calculations Legislation

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 between new build, extension and conversion projects.

New build SBEM calculations work out a Target Emission Rating (TER) followed by a Building Emission Rate (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.

When non-domestic buildings are extended the above SBEM calculation rules apply but only to the new build portion of the building. The SBEM requirements do not apply to the existing section of the building.

SBEM calculations for conversion projects are different however. The SBEM report needs to show that the thermal elements such as walls, floors and glazing have been updated to minimum standards.

For any further information on SBEM calculations feel free to call and speak to one of our experienced assessors.
