SBEM (Simplified Building Energy Model) is a software which calculates the monthly energy use and carbon dioxide emissions of a commercial new build. 

It is used to demonstrate compliance with Part L2 of Building Regulations. SBEM calcs are a mandatory requirement for any heated new build commercial building exceeding 50m2 in floor area. 

  • Design Stage – Building Control require a Design Stage SBEM Calculation to be submitted with your Building Regulations Application. Without the SBEM Calculation, Building Control will not allow the project to start on site. 
  • As-built Stage – Building Control require an As-built Stage SBEM Calculation and EPC when the building is completed. Without this information it is unlikely that the building will achieve final Building Control approval.

Pricing will vary depending on size and complexity of the project.
