Architectural Services, SAP & SBEM


SAP (Standard Assessment Procedure) was developed by the Building Research Establishment (BRE) for the former Department of the Environment and was based on the BRE Domestic Energy Model (BREDEM). SAP was first published in 1993 and has since been updated periodically, in 1998, 2001, 2005, 2009, 2012, and most recently in 2022.

In 1994, SAP was first cited in the Building Regulations as the means of assessing the energy performance of dwellings. In 2007 it was adopted as the methodology behind Energy Performance Certificates (EPCs).


SBEM is used to demonstrate the energy performance of new and existing non-domestic buildings.
SBEM stands for ‘Simplified Building Energy Model’. It is a government approved methodology that calculates the energy required to heat, cool, ventilate and light a non-dwelling.

Assessed based on a 12-month period of ‘normal’ use it gives an accurate picture of the amount of the energy and carbon dioxide emissions of the building and therefore how energy efficient (or not) the building is. Non-domestic buildings include offices, warehouses, retail units, restaurants, leisure centres and retirement homes.
