Simplified Building Energy Model (SBEM)

Simplified Building Energy Model (SBEM)

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), the Energy Performance of Buildings Directive (EPBD) and the Green Deal.

The tool is currently used 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 on construction and at the point of sale or rent.

EPCs have been criticised for a lack of accuracy, or alignment with actual operational energy use, although they remain an important tool for raising awareness and giving an indication of how a home or building is designed to perform. 

The Energy Act 2012 put EPCs centre stage by passing legislation that is expected to ban the letting of F and G rated buildings from 2018 onwards, in both domestic and commercial markets – a principle which UK-GBC fully supports. Read more about ‘minimum performance standards’ here.
