SBEM Calculations (Part L2A)

SBEM is the Government’s methodology for analysing the energy consumption of new and existing non-domestic buildings. It is used for compliance with Building Regulations Part L2 and for the production of Energy Performance Certificates (EPC).

Part L2a of the building regulations require all new non-domestic buildings to prepare a SBEM calculation at early design stage in order to demonstrate that the building’s energy emission rate is lower than a target emission rate. This form of calculation can assess and compare different building types with respect to their thermal performance, fuel supply and services specification. Energy Performance Certificates (EPCs) are generated from the calculations and are mandatory for all new buildings and prior to sale/rent for existing buildings.

Green Castle Energy use dynamic modelling software to undertake detailed modelling in order to meet Part L2A requirements. From this early analysis we can then provide technical advice to achieve Part L compliance.
