SBEM (Simplified Building Energy Model), SAP (Standard Assessment Procedure) and EPC (Energy Performance Certificate) calculations are all government-approved methods for measuring energy use and demonstrating Part L2A building regulations compliance for domestic and non-residential buildings.

These calculations give a consistent and reliable evaluation of a building’s energy use through regular analysis of thermal performance and carbon dioxide (CO2) emissions, whilst also taking into account the building’s planned use, geometry, orientation, air conditioning (HVAC), lighting, heating and ventilation systems.

At Build Check, our team of experienced and accredited engineers take pride in guiding customers through what is required for each phase of your building project, from design through to final reporting.

The Simplified Building Energy Model (SBEM) is a method used to measure energy consumption in non-domestic buildings to generate Energy Performance Certificates and shows compliance with Part L/F 2013 of Building Regulations.

The Standard Assessment Procedure (SAP) is the calculation method for domestic buildings to demonstrate Part L/F 2013 compliance for Energy Performance Certificates (EPCs) and Building Energy Rating (BER) Certificates

The Energy Performance Certificate (EPC) is required for all buildings that are to be rented or sold as it shows the likely energy consumption and the carbon dioxide (CO₂) emissions for the property and gives an energy performance rating for the building.
