What is an SBEM Calculation and when do I need one?

SBEM stands for the Simplified Building Energy Model and is used in assessing the Energy Performance of Buildings and is used all non-domestic buildings and forms part of the Building Regulations in England and Wales.

Why do I need an SBEM Calculations?

The Building Regulations for England and Wales Compliance Part L2 require all new commercial properties to be assessed using the SBEM calculations for energy performance of buildings. The BRUKL and SBEM outputs comprise of detailed report highlighting the energy demands of the building in use including the subsequent running costs of the building.

Part L2 of the Building Regulations (England and Wales) also requires that the Building Emission Rate (BER) should be equal to or lower than the Target Emission Rate (TER) for the building. The SBEM Calculation is used to show compliance with this part of the regulations.

If you have a domestic property you need testing, instead of a SAP Assessment you will require a SAP Calculations which we can undertake for you.

  • As Built Stage: At the as built stage we send you an SBEM Summary detailing the specification we have within the calculation, we can then register the address with Landmark if required and where applicable enter the air test figure and lodge the EPC. We can even send Building Control the SBEM, BRUKL Compliance Document and EPC on your behalf. We can also undertake the air tightness test to make your life that little bit easier.
