What Is a Level 5 EPC?
A Level 5 EPC (Energy Performance Certificate) is required for complex commercial buildings that cannot be accurately assessed with standard software. Unlike Level 3 or 4 EPCs, Level 5 certificates use Dynamic Simulation Modelling (DSM) to provide a detailed digital representation of your building’s energy performance.

Dynamic Simulation Modelling EPC (DSM EPC)
Our Level 5 EPCs are powered by IES-VE DSM software, which accounts for:
-
- Hourly weather and climate data
- Heating, cooling, and ventilation systems
- Building fabric, glazing, and shading features (e.g., brise soleil)
- Zoning and advanced energy systems
This ensures a more precise EPC rating — often better than standard iSBEM-based assessments.
When Do You Need a Level 5 EPC?
You’ll need a Level 5 EPC if your building includes:
-
- Complex HVAC or renewable energy systems
- Atriums, shading devices, or advanced facades
- Large, mixed-use or uniquely designed spaces
