Developed by the BRE

SBEM is a software tool developed by BRE for the Deparment for Communities and Local Government. It provides an analysis of a building's energy consumption, and is used for non domestic buildings in support of the National Calculation Methodology (NCM), the Energy Performance of Buildings Directive (EPBD) and the Green Deal. iSBEM is the latest software tool and can be downloaded free of charge from the dedicated National Calculation Methodology website. cSBEM was created to accompany the recent consultation for Part L (2013) of Building Regulations.

Compliance with Part L

SBEM determines CO2 emission rates for new buildings in compliance with Part L of the Building Regulations. It is also used in the equivalent Regulations in Scotland, Northern Ireland, the Republic of Ireland and Jersey. It is used to generate Energy Performance Certificates (EPCs) for non-domestic buildings on construction,  at the point of sale or rent.

Integrated assessment

Our energy consultancy team are accredited SAP and SBEM assessors. We provide SBEM together with other assessment practices to bring continuity in the design philosophy and energy solution. This creates a simple site-wide specification, that is efficient and reduces costs.
