SBEM Calculations for Wales

SBEM Calculations for Wales

Part L2A of Building Regulations requires that a Simplified Building Energy Model (SBEM) calculation is completed to ensure compliance for new build commercial projects .

Elmhurst Energy Consultancy uses approved industry software to calculate the energy performance of commercial properties for compliance with Part L2A of Building Regulations . We can also use SBEM Calculations to produce a non-domestic Energy Performance Certificate (EPC) required when marketing a property for sale or let. 

What is a SBEM Calculation?

An SBEM calculation predicts the energy performance of commercial buildings in order to prove compliance with Part L of the Building Regulations (England and Wales). The results of a SBEM calculation are used to produce an Energy Performance Certificate (EPC), which is needed before being sold or let.  

In order for a new building to comply, the Building Emission Rate (BER) must not exceed the Target Emission Rate (TER) which is taken from a notional building of the same type, shape and size. 

When is a SBEM Calculation required? 

Most new commercial buildings over 50mwill require an SBEM Calculation for Building Standards compliance. 

As mentioned previously, SBEM Calculations are required before a property is built (at Design Stage) and after construction (As-Built). More information regarding the requirements at each stage are linked below.

Buildings that do not require a SBEM

  • Temporary buildings with a planned use of less than two years. 
  • Industrial sights, workshops, and non-residential agricultural buldings with a low energy demand. 
  • Stand-alone buildings with a total useful floor are less than 50m2
