Part L2B SBEM Calculations – Non-Domestic Refurbishment & Extensions

SBEM (Simplified Building Energy Model) provides an analysis of the energy consumption of buildings other than dwellings; it is used in support of the National Calculation Methodology and the Energy Performance of Buildings Directive. A SBEM is required for all new building and extensions which are in excess of 100m2 and more than 25% of the original building. SBEM’s are used to show compliance with Part L Approved Documents L2A and L2B of The Building Regulations 2000 (as amended).

If you are extending a commercial building 100m2 and it is more than 25% of the original building then an L2B SBEM calculation will be required by building control.

We have extensive experience in this area and can help to comply with the regulation whilst also being cost conscious as to how we tackle upgrades, material specifications and any subsequent air testing.

Our team can do these calculations within 7 – 10 days from instruction.
