When a building has any form of significant shading then a Level 5 EPC (DSM) model should always be carried out, while Level 3 & 4 EPCs use the simple daylighting method, when a building has no significant shading (window and local shading, self-shading and site shading), and when daylight control is not installed or important. Based in Sheffield, NRG Focus provide Level 5 EPCs throughout Leeds, York, and the surrounding areas of Yorkshire, as well as serving the whole of the UK.
Level 3 & 4 EPCs are only concerned with external windows and doors. However, internal openings can be included in DSM calculations allowing light from an atrium to flow into internal offices, thus reducing the lighting load of the building.
The correct selection and use of a DSM model can reduce your MEES risk, ensuring the building does not fall within the F or G rating, resulting in a lettable building as of 1st April 2018.
Dynamic Simulation Modelling
Buildings that fall under Level 5 of EPC assessment require Dynamic Simulation Modelling (DSM) and are naturally more complex, including one or more of either Atria, Automatic Blind Control, or Enhanced Thermal Coupling to the Structure, with or without Ventilation.
Dynamic Simulation Modelling allows more accuracy in terms of analysis, but also modelling. External shading devices can be included within the calculations and these, for example, may help reduce the energy requirements of a ventilation or cooling system, and therefore improve the building’s energy rating. Advantages of Dynamic Simulation Modelling include:
- Hourly weather data with time-step control
- Orientation and PV inclination modelled at 1 degree 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
