To demonstrate compliance with the Building Regulations Part L, all new non-domestic buildings, some extensions and conversions require assessments through SBEM calcualtions.
Using an approved SBEM software, the CO2 emission of a building can be calculated based on the building specifications. This CO2 emission is refered to as the Building Emission Rate (BER). For a building to be compliant with the regulations, the BER must not be greater than the TER (Target Emission Rate).
SBEM Calculations are carried out in two stages: Design Stage & Built Stage.
