New Build SBEM
New Build Simplified Building Energy Model (SBEM) Calculations are a mandatory requirement for any heated, new commercial building exceeding 50m2 floor area.
SBEM calculates the energy cost and carbon emissions generated to heat, light, ventilate, cool and provide hot water to a building. SBEM calculations are also used to show compliance with Part L of the Building Regulations, and should be applied from the design stage of the build process.
As with residential buildings, Building Control will not issue a completion certificate until a valid EPC has been produced by a certified Energy Assessor.
