SBEM Calculations

An SBEM, or simplified building energy model, provides an analysis of the energy consumption of a building. The SBEM calculates the monthly carbon dioxide emitted and energy used by a building given its construction, geometry, use, lighting equipment and HVAC. To obtain your SBEM ratings, please contact our offices.

SAP Calculations

SAP is the Governments 'Standard Assessment Procedure' for energy rating of dwellings. SAP, was designed to be included in the 1995 Building Regulations and it is now a compulsory component in Part L of the Regulations. Every new house has to have a SAP rating.

SAP is calculated by a procedure contained in the Building Regulations, which predicts heating, and hot water costs. These depend on the insulation and air tightness of the house and the efficiency and control of the heating system. The calculation uses the Building Research Establishment's Domestic Energy Model (BREDEM).

Display Energy Certificates (DEC's)

A Display Energy Certificate (DEC) provides an overview of the annual energy consumption of a building based on data obtained from the gas, electricity and water meters. The certificate is accompanied by a mandatory advisory report which outlines potential measures for improving the energy performance of the building. The certificate must be replaced every year and a new advisory report generated every 7 years.

At present Display Energy Certificates are only required for buildings occupied by a public authority or an institution providing a public service to a large number of persons. However, the Government has announced its intention to review in the future whether this regulation should be extended to include private sector buildings occupied by commercial organisations and visited frequently by members of the public.
