SBEM Calculations

You will need to have an SBEM calculation completed if you are planning to construct a new commercial or non-domestic building. With strict emission targets to meet, getting the specification right on your development is more important now than ever.

SBEM Calculations - At what stage(s) does this apply during your build?

What is an SBEM Calculation?

SBEM, or Simplified Building Energy Model, is a calculation required for newly-built, commercial or non-domestic buildings. The term ‘non-domestic’ refers to warehouses, offices, hotels, shops… any building that requires heating and lighting that isn’t a house. An SBEM is essentially a calculation for modelling your design and checking compliance with CO2 targets.

The SBEM model is created at Design Stage using design drawings and is checked against building regulations (Approved Document Part L in England and Wales, and Technical Handbook Section 6 in Scotland). To show compliance on new builds, the Building Emission Rate must be equal to or better (lower) than the target.

An SBEM may also be required for existing buildings that are being extended or renovated.

Top Tips for SBEM

  • A design stage SBEM must be submitted to your Building Control Officer (BCO) before starting on site and a revised ‘As Built’ SBEM is required at the end of the build. The ‘As Built’ SBEM is used to produce an EPC (Energy Performance Certificate).

  • Our accredited SBEM assessors can help you find efficient routes to compliance. 

  • Energy use in buildings varies significantly so it’s difficult to predict the result of an SBEM. Lighting is one of the biggest influences. 

  • If your building is greater than 500m² consider your Air Tight Barrier Line early.

The Energist Approach

  • Our team understand your deadlines and provide a same day response. We’re right by your side and offer a 72 hour fast track service so you won’t be kept waiting.

  • We work as an extension to your design team to review your plans before liaising directly with your Building Control Officer and Design Team (if you want us to).

  • We complete all three parts of your SBEM Calculations plus your Acoustic and Air Leakage Testing.

  • We will keep you informed, share our knowledge and email your report within your deadlines.
