SBEM Calculations

What are SBEM calculations and why are they necessary?

Understanding SBEM
SBEM (Simplified Building Energy Model) calculations are a legal requirement for all new commercial buildings, and for many extensions or conversions, across the UK.

These calculations show whether a building meets the energy efficiency standards set by Building Regulations Part L. The process uses data from your plans and specifications to predict energy use, carbon emissions, and compliance.

Why SBEM matters
SBEM calculations are not just a formality. Without them, you cannot secure Building Control sign-off or get an Energy Performance Certificate (EPC), both of which are required for occupation, sale, or letting. They help prevent expensive rework and delays.

Early engagement with SBEM allows you to make informed decisions about materials, insulation, heating, lighting, and ventilation—so you can avoid common pitfalls and extra costs later on.

At enevo, our expertise means we spot issues before they cause problems, keep your project on schedule, and help you achieve compliance efficiently.
