What is DSM?

DSM (Dynamic Simulation Modelling) is an extremely accurate and powerful tool for assessing the environmental performance of a building.

It can be used to model and analyse a range of sustainability factors from energy compliance and CO2 emissions, to overheating and daylighting analysis.

DSM in Use

DSM is much more commonly used for analysis of non-domestic schemes – for example large, mixed use developments like hotels, office blocks or other complex commercial property. However we are seeing an increasing demand for it’s use on residential developments.DSM

Many of our clients are M&E consultancies and engineers – and having the ability to carry out detailed analysis can assist early stage building services design and ensure that planning obligations (i.e the London Plan), client requirements and regulatory burdens can be met on the ground.

DSM allows a much more accurate analysis than is possible with standard Part L energy assessment tools such as SAP and SBEM. This is partly due to a much greater emphasis on external factors such as solar gain and the effect of glazing and thermal mass, but also due to more accurate occupancy, behavioural and energy use profiles.

Dynamic Simulation Modelling –  The Process

The DSM process starts with geometry – the assessor will create an exact 3D model of the building. Software tools (commonly recognised versions include IES or TAS) then have built in modules to allow the detailed analysis of:

  • Thermal Performance and Construction
  • Renewables and Technologies
  • Energy use
  • CO2 Emissions
  • Overheating
  • Daylight and Sunlight Assessment
  • Ventilation and Airflow
  • Occupant Comfort
  • BREEAM / LEED Performance

"BE are fantastic, local building energy assessors, with competency across many areas. We have found them very useful on small and large projects. With the larger projects they can provide a range of assessments with one point of contact. We submitted a planning application for 224 residential apartments for a site in Luton. BE provided the flood, acoustic, heat loss and SUDS reports. The scheme was consented and reports were excellent. We have found them to been frank and honest with their advice. They are also lovely people to work with… which is very important."
