SBEM/EPC Calculations

For all our clients we offer a tailored package of building compliance support services specifically designed to meet the project at hand.

For developers who are involved in the new build, conversion or extension of commercial premises, including industrial and retail premises. The preparation of the required SBEM (Simplified Building Energy Model) Calculation and EPC (Energy Performance Certificate) are part of a two-stage process as required by Part L2 of the Building Regulations:

• Design stage – prior to commencement of the development project, an SBEM Calculation must be submitted to your local building control, alongside your application
• As-built stage – upon completion of the building phase, it is required that both an SBEM Calculation and an EPC are submitted prior to sign-off by building control

The SBEM Calculation is used to calculate the energy performance for commercial premises, including: offices; warehouses; retail outlets; hotels and pubs; care homes; community buildings.

The Energy Performance Certificate (EPC) provides an estimate of the likely energy consumption and ultimately the carbon dioxide (CO₂) emissions for the property, including consideration of:
• Heat loss through the building fabric
• Efficiency of heating and ventilation systems
• Types of lighting which is installed
• Planned activity for building use

The EPC shows an A to G energy performance rating for the building and is required for all buildings that are to be rented or sold.

At ATSPACE, our fully qualified assessors follow an established process for providing advice, guidance and support – from design stage through to submission of the final reports that must be uploaded to the Landmark database, once the as-built stage has been fully assessed.

Our aim is to help our customers every step of the way. We have every confidence that our team of skilled, experienced and certified assessors and engineers can help you achieve building compliance success through each phase of your project.
