Our Services > SBEM Calculations

Building Regulations Services Ltd provide an efficient speedy service should you require a SBEM calculation for your project.

SBEM is a computer program that provides an analysis of a building's energy consumption. SBEM calculates monthly energy use and carbon dioxide emissions of a building given a description of the building geometry, construction, use and HVAC and lighting equipment. It was originally based on the Dutch methodology NEN 2916:1998 (Energy Performance of Non-Residential Buildings) and has since been modified to comply with the emerging CEN Standards.

SBEM makes use of standard data contained on associated databases and available with other software.

The purpose of SBEM and its interface iSBEM is to produce consistent and reliable evaluations of energy use in non-domestic buildings for Building Regulations Compliance (and eventually for Building Performance Certification purposes.) Although it may assist the design process, it is not primarily a design tool. It does not calculate internal temperatures, for example.

As iSBEM is a compliance procedure and not a design tool, if the performance of a particular feature is critical to the design, even if it can be represented in SBEM, it is prudent to use the most appropriate modelling tool for design purposes. In any case, SBEM should not be used for system sizing.

What is SAP?

SAP is the government's approved methodology for calculating the energy performance of buildings. It is used to demonstrate compliance with Building Regulations Part L requirements and to produce Energy Performance Certificates for new buildings.

The score is based on factors such as insulation, air tightness, heating systems, ventilation and lighting. Renewable technologies such as solar power are also taken into account.

How can I submit my drawings?
