Dynamic Simulation Modelling (DSM)

What is DSM, how does it compare with SBEM?

DSM stands for Dynamic Simulation Modelling.

This is also sometimes known as thermal modelling. DSM calculations are more powerful than SBEM and therefore more accurately reflect the building being modelled. It uses an hourly simulation taking into account the different internal and external building parameters on hourly time steps rather than the monthly average on a steady state for the SBEM methodology. In the majority of cases it is therefore beneficial to use DSM instead of SBEM. There are also now more than often instances when DSM must be used due to the complexity of the building. For instance, if the building design incorporates an atrium, or includes important shading devices or the other features such as night time cooling with thermal coupling. Our philosophy is that at HRS we will use DSM assessment in the majority of cases, with market leading IES-VE software as a standard, due to the benefits it offers and to standardise the work flow with other services.

What does DSM stand for?

DSM stands for Dynamic Simulation Model. This is also known as thermal modelling.

When would I need a DSM?

If your building design is complicated or has an unusual heating, cooling or ventilation strategy, then you may need a DSM (Dynamic Simulation Model). This model can be tailored to be more reflective of a complicated design. It is worth knowing that if your building design incorporates extensive glazing, non-standard wall or roof shapes or a bespoke services strategy then there is a strong possibility that you will need a DSM (Dynamic Simulation Model). If you are unsure, please contact the HRS Energy team who would be more than happy to help.
