SBEM & National Calculation Methodology
Everything you need to know about the Simplified Building Energy Model and the National Calculation Methodology for non-domestic building compliance.
What Is SBEM?
How the Simplified Building Energy Model works, what it calculates, and when to use it for non-domestic compliance.
NCM Modelling Guide
The National Calculation Methodology modelling guide – notional building specifications and standard operating conditions.
iSBEM Updates
What has changed in iSBEM for the Future Buildings Standard, including new inputs and calculation features.
Dynamic Simulation Modelling
When and why to use approved DSM software instead of SBEM for complex non-domestic buildings.
Carbon Emission Factors
Updated carbon emission factors and primary energy factors used in SBEM calculations under the FBS.
The Simplified Building Energy Model (SBEM) and the National Calculation Methodology (NCM) form the backbone of non-domestic building energy compliance in England. Whether you are using iSBEM or approved Dynamic Simulation software, understanding the NCM framework is essential for demonstrating that your building meets the Future Buildings Standard.
