What is Dynamic Simulation Modelling?
Dynamic Simulation Modelling (DSM) packages use actual building geometry, details of construction materials, HVAC design strategies (including renewables), solar gain, occupancy data and hourly (or even sub-hourly) weather data to enable the performance of the building to be modelled for a wide range of purposes, from design development through to Building Regulations compliance.
Once a DSM model has been produced, it can be used for many simulation tasks, such as:
- Building Overheating (CIBSE TM52 and TM59)
- Heating, Cooling and Ventilation Sizing
- Predicted Energy Consumption and Energy Reduction
- Computational Fluid Dynamics (CFD)
- Highly detailed Building Regulations Part-L assessment (more accurate than standard SBEM based checks)
- Level 5 commercial EPCs
The ‘performance’ of the building can be quantified in a number of different ways, including energy consumption, peak summer time temperatures and the adequacy of ‘passive’ engineering solutions, such as thermal mass, solar shading and natural ventilation.
DSM packages therefore have many advantages as a design tool over compliance only ‘steady state’ software such as SBEM which can only usefully assess compliance with the Building Regulations and are not appropriate as a design tool.
As with any model using weather data and anticipated occupant behaviour, a DSM package is not able to provide a guarantee of future performance, but instead can be used to compare alternative designs and/or other buildings on a regulated, like for like basis. DSM packages should be used appropriately and with caution, particularly where ‘automated’ control of systems is assumed.
