SBEM Calculations & EPC's - New builds, Conversions, Extensions

All new non-residential buildings must comply with Part L2A of the Building Regulations on buildings of 50m2 or more; the Simplified Building Energy Model (SBEM) is an approved method for undertaking Part L2A compliance calculations.

Simplified Building Energy Model (SBEM) calculates the energy used and CO2 emissions generated by a building, through the modelling of the building’s features, including:

  • Building Geometry, location and orientation
  • Thermal Performance (U-values, air tightness)
  • Building Services (HVAC)
  • Lighting
  • Controls

Part L2A 2013 compliance requires an additional 9% reduction required in CO2 emissions compared to 2010 standards, meeting compliance requirements with Part L2A 2013 is becoming increasingly more challenging.
