Simplified Building Energy Model (SBEM)
UK Building Regulations compliance and Energy Performance Certificate (EPC) creation must be undertaken using the relevant calculation tool specified in the National Calculation Methodology (NCM). SBEM was developed by the BRE for the Department for Communities and Local Government and is used for non domestic buildings in support of the National Calculation Methodology (NCM) and the Energy Performance of Buildings Directive (EPBD).
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, the tool helps to determine CO2 emission rates for new & existing buildings by calculating the monthly energy use of a building given a description of the building geometry, construction, use and HVAC and lighting equipment. It is also used to generate Energy Performance Certificates for non-domestic buildings. |
