SBEM Calculations

Our low cost approach to SBEM calculations includes:

  • A review of your plans and specifications
  • Recommended improvements where needed
  • Design stage SBEM calculations
  • Guidance on achieving the required standard.
  • As Built SBEM and EPC
  • All required documents for submission to Building Control

The more energy efficient the building is, the lower the overall energy consumption will be. Which in turn lowers the CO2 emission rates for the building.

Residential buildings tend to focus more on creating the most efficient building fabric, to cut down on the need for constant heating. While commercial units are more affected by heating, cooling, ventilation systems and lighting with all the relevant building services.

Design Stage SBEM Calculations

During the design stages of the development, the energy assessor will carry out SBEM calculations. These will comply with Part L England, Wales, Northern Ireland and Section 6 Scotland. Once the design is achieving compliance, the build can commence. Further calculations are then carried out at as built stage once the property is ready for completion.

As Built Stage SBEM Calculations

The As built stage is essentially just confirmation that the design has been carried out as specified and that no deviations have been made.

If alterations have been carried out then they will be modelled in. But this may affect whether the calculation still achieves a pass.  The property cannot be issued with and energy performance certificate (EPC) until the SBEM calculation is passing the required targets.

What is an SBEM?

SBEM stands for ‘Simplified Building Energy Model’. This is the software tool which is used by non-domestic energy assessors to carry out an energy calculation on a commercial building. These calculations can be carried out on new builds, conversions, extensions and existing dwellings that are being sold or let.

Similar to residential SAP calculations, the aim is to achieve compliance with part L of the Building Regulations (part L2a & L2b). The target is to ensure the building emission rate (BER) is below the target emission rates (TER).

BRUKL Reports

The BRUKL Report provides the Building Energy Rating (BER) of a Commercial Building. The BER has to be lower than the Target Energy Rating (TER) in order for the building to pass Part L2 of the Building Regulations for England and Wales.

At building design state, BRUKL reports are an important tool to ensure that the building is energy efficient and compliant.
