SBEM: Simplified Building Energy Model

SBEM is a software tool developed by BRE that provides an analysis of a building's energy consumption.

SBEM is used for non domestic buildings in support of the National Calculation Methodology (NCM) and the Energy Performance of Buildings Directive (EPBD).

The tool helps to determine CO₂ emission rates for new buildings in compliance with Part L of the Building Regulations (England and Wales) and equivalent Regulations in Scotland, Northern Ireland, the Republic of Ireland and Jersey. It is also used to generate Energy Performance Certificates for non-domestic buildings in construction, for sale or let.

SBEM was developed by BRE for the Department for Communities and Local Government. The latest version of the SBEM tool and its accompanying user interface, iSBEM, can be downloaded free of charge from the dedicated National Calculation Method website at http://www.ncm.bre.co.uk/ (opens in a new window).

A variant of the SBEM tool is now in use in Cyprus and developments are underway for other countries, initially in Europe.
