SBEM’s and final EPC’s from James Steward

Our partners can provide SBEM calculations and EPCs for non-domestic and commercial buildings in accordance with Regulations L2A (New buildings) and L2B (existing buildings)

SBEMs:
An SBEM calculation (Simplified Building Energy Model) is required to determine the energy ratings of a non-domestic or commercial building. This in turn is used to provide leakage rates for Air Tests and evidence for the EPC.

EPCs:
An EPC (Energy Performance Certificate) provides an indication of the building’s performance, shown as an A-G Carbon dioxide (CO2) based index.

• When a building is constructed or modified the builder must supply an EPC to the customer
• When a building is offered for sale the seller must provide an EPC to the prospective buyer
• When a building is being let the prospective landlord must provide an EPC to prospective tenants

EPC requirements:
As from October 1st 2008 all buildings that are not dwellings require an Energy Performance Certificate produced by qualified and/or accredited energy assessors.

EPCs are valid for 10 years, subject to changes in the property and tenancy.

SBEMs:
An SBEM calculation (Simplified Building Energy Model) is required to determine the energy ratings of a non-domestic or commercial building. This in turn is used to provide leakage rates for Air Tests.
