- Abstract
- Description
The EU Energy Performance of Buildings Directive requires member states to create a methodology for calculating the energy performance of buildings. The Simplified Building Energy Model (SBEM), developed by BRE for the Communities and Local Government Department as the default calculation tool for non-domestic buildings in the UK, enables Building Regulations compliance checks and energy ratings to be carried out on a consistent basis. This paper describes the basis of SBEM, the input information it requires and the energy consumption issues included in the calculation. It explains the roles of SBEM, iSBEM, BRUKL and EPCgen. It also considers other potential uses of SBEM beyond its core regulatory and certification functions. The paper supersedes IP 2/07, which is now withdrawn.
