Dynamic Simulation Modelling, DSM, rather than SBEM is required to produce EPCs for Level 5 buildings. The assessor must be qualified as a Level 5 assessor. A building is considered Level 5 where one or more of the of the following are present in the building.

Atria

Enhanced Thermal Coupling to Structure

Automatic Blind Control

Dynamic Simulation Modelling

The Key advantages of Dymanic Simulation Modelling

• Hourly weather data with time-step control

• Orientation and PV inclination modelled at 1degree increments

• Ability to model geometry in more detail for better results

• The inclusion of internal openings

• Improved modelling of glazing and solar shading and reflection

• Inter-zone heat transfer and better modelling of thermal mass

• Overall more accurate analysis
