Non-Domestic New Build (SBEM)

A Simplified Building Energy Model (SBEM) is used to calculate the compliance of a new build non domestic property with Part L Building Regulations.

The Building Regulations for England and Wales Compliance Part L2 require all new buildings, refurbishments or extensions over 50m² to be assessed using SBEM calculations to show the energy efficiency rating.

The SBEM calculation provides a carbon footprint of the proposed building and indicates the energy costs and carbon emissions generated at the design state of the project. The SBEM calculations will consider the following elements:

• Orientation
• Floor, Wall & Roof Construction
• Windows & Doors
• Heating & Cooling Systems
• Controls
• Water Heating System
• Ventilation
• Lighting

Once the construction has been completed and all works have been carried out as per the SBEMspecifications, the EPC is produced from the SBEM calculations.
