Commercial EPCs – SBEM Calculations

From the 1st October 2008 all commercial buildings will require an EPC on sale, rental or construction. Sellers and landlords will be required to provide EPCs for all or parts of buildings when they are sold or rented. Please contact us for further advice and guidance.

Although similar in appearance to Domestic EPCs, Commercial EPCs are generated using the Simplified Building Energy Model (SBEM) which complies with the National Calculation Methodology. Calculating the energy rating of the building involves complex calculations involving:

  • The architectural layout, including geometry, dimensions and type of usage (i.e. office or industrial).
  • The type and thermal performance of the building construction, including walls, roofs, floors and glazing.
  • Building Services: heating, cooling, ventilation and hot water systems.
  • Lighting and associated controls.
  • Usage of Low Carbon/Renewable Technology: (Solar Thermal Hot Water, Photo Voltaics, Wind Turbine etc.).

Part L

A new revision of Part L (Conservation of Fuel & Power) of the Building Regulations came into force in April 2006. Compliance with Part L2A and L2B can now be demonstrated using SBEM.
