SBEM Calculations - BRUKL
What is SBEM?
SBEM or the Simplified Building Energy Model is a government approved methodology used to calculate the building's energy performance, and can be used to demonstrate compliance with Part L of the Building Regulations (BRUKL) by comparing the designed Building Emission Rate (BER) with an SBEM calculated Target Emission Rate (TER).
SBEM calculations assess the overall efficiency of the building and also the amount of energy that will be required for the building services Inc. heating, cooling, lighting, ventilation and hot water systems once the building is operating.
Buildings requiring a SBEM Calculation
SBEM calculations are required for all newly built non-domestic units with a heated or cooled environment and an internal floor area greater than 50m2 to ensure that they meet the requirements of Part L2A of the Building Regulations.
Newly constructed commercial buildings require an initial SBEM calculation to be carried out at the design stage to confirm that the specification such as insulation and the fixed building services (heating, lighting and ventilation) will meet minimum building regulations. When the construction of the building is complete the performance is re-checked and adjusted to illustrate and analyse any changes to the specification or materials used during construction to confirm the building is consistent with the BER and the as built calculations are produced.
