What Are SBEM Calculations?
SBEM (Simplified Building Energy Model) calculations are the UK government’s approved method for assessing the energy performance of non-domestic buildings. They measure a building’s energy use, CO₂ emissions, and compliance with Part L of the Building Regulations (Conservation of Fuel and Power).
Why Are SBEM Calculations Needed?
- Regulatory Compliance – Required for new commercial buildings, extensions, and refurbishments.
- Energy Performance Certificates (EPCs) – Determines the energy rating of a building.
- Sustainability & Cost Savings – Helps improve energy efficiency and reduce operational costs.
Key Elements of SBEM Calculations:
- Building Fabric Performance – Insulation, airtightness, and thermal bridging.
- Heating, Cooling & Ventilation – Efficiency of HVAC systems.
- Lighting – Energy-efficient lighting and controls.
- Renewable Energy Integration – Solar panels, heat pumps, CHP (Combined Heat & Power).
- Occupancy & Usage Patterns – How the building is used and its impact on energy demand.
- Carbon Emissions – Predicted CO₂ output of the building.
When Are SBEM Calculations Required?
- At Design Stage – To demonstrate compliance before construction.
- As-Built Stage – To confirm final energy performance for certification.
