SBEM Calculations
SBEM (Simplified Building Energy Model) calculations assess energy performance in non-domestic buildings, predicting energy use, CO₂ emissions, and compliance with Part L of the Building Regulations.
Request a QuoteWhy SBEM Matters
SBEM calculations are essential for new commercial buildings, extensions, and refurbishments. They help determine energy ratings for EPCs, ensure regulatory compliance, and identify opportunities to improve efficiency and reduce operational costs.
By analysing building fabric, systems, and usage patterns, SBEM provides a clear picture of energy demand and carbon emissions, enabling smarter design decisions.
Core Components of SBEM Calculations
Building Fabric
Insulation, airtightness, and thermal bridging performance.
HVAC Systems
Heating, cooling, and ventilation efficiency.
Lighting & Controls
Energy-efficient lighting and automated control systems.
Renewables
Integration of solar panels, heat pumps, or CHP systems.
Occupancy & Usage
Impact of building use patterns on overall energy demand.
Carbon Emissions
Prediction of CO₂ output for regulatory and sustainability planning.
When SBEM Calculations Are Needed
SBEM is typically carried out at two key stages:
- Design Stage – Demonstrates compliance before construction begins.
- As-Built Stage – Confirms final energy performance for certification and EPC issuance.
Benefits of SBEM Analysis
- Regulatory compliance with Part L
- Improved energy efficiency and operational savings
- Clear insight into building performance for design optimisation
- Supports sustainability and carbon reduction goals
Energy Savings
Identify areas for reduced energy consumption.
Lower Carbon Emissions
Optimised systems and materials help minimise CO₂ output.
Regulatory Confidence
Ensure compliance with Building Regulations Part L.
Better EPC Ratings
High-performing buildings achieve improved energy ratings.
