Nationwide can provide SBEM calculations for all commercial buildings, including:
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.
