SBEM Calculations

Understanding SBEM Calculations

Simplified Building Energy Model (SBEM) calculations are a key requirement for demonstrating compliance with Part L of the Building Regulations in the UK. They assess the energy efficiency of non-domestic buildings by calculating their energy consumption and carbon emissions.

What Are SBEM Calculations?

SBEM is a government-approved methodology used to evaluate the energy performance of new and existing commercial buildings. It provides an energy rating based on factors such as:

• Building fabric and insulation levels

• Heating, cooling, and ventilation systems

• Lighting efficiency

• Renewable energy integration

SBEM assessments generate a Building Emission Rate (BER), which must be lower than the Target Emission Rate (TER) to achieve compliance with Part L.

When Are SBEM Calculations Required?

SBEM calculations are needed at key stages of a building’s lifecycle:

• New builds: Required at the design stage and upon completion to obtain a BRUKL report and an EPC.

• Extensions and refurbishments: Necessary for large extensions or major renovations affecting energy performance.

• Change of use: Needed when converting a building to a different usage category.

Why Are SBEM Calculations Important?

SBEM calculations ensure that buildings meet energy efficiency regulations, supporting the UK’s net-zero carbon targets. Benefits include:

• Regulatory compliance with Part L and planning requirements.

• Lower operational costs through improved energy performance.

• Enhanced sustainability credentials for property owners and developers.

• Higher EPC ratings, increasing marketability and asset value.
