What is Dynamic Simulation Modelling?

Dynamic Simulation Modelling (DSM), also known as thermal modelling, is a highly accurate tool for assessing a building's environmental performance. It encompasses energy compliance, CO2 emissions, thermal comfort (overheating), and daylighting analysis. DSM is particularly valuable in non-domestic schemes such as large, mixed-use developments, and is increasingly used in residential projects.

The Brief History of DSM in the Built Environment

DSM has evolved to become a crucial part of sustainable building design and assessment. Its roots trace back to the late 1950s with the development of Systems Dynamics at MIT. Over the years, DSM has grown to include various modelling techniques, each adapted to better understand and simulate the complex interactions within building environments.

Why DSM is Required in the Built Environment

In the built environment, DSM is essential for achieving sustainable and energy-efficient building designs. It provides a detailed analysis of a building's performance, considering factors like solar gain, the effect of glazing, thermal mass, and more accurate occupancy and energy use profiles. This level of detail surpasses what is possible with standard Part L energy assessment tools, making DSM invaluable for meeting planning obligations and regulatory requirements.

How DSM Calculations are Completed

DSM involves creating a precise 3D model of the building. Advanced software tools are then used to analyze various aspects such as thermal performance, construction, renewables, energy use, CO2 emissions, overheating, daylight and sunlight, ventilation, and occupant comfort. This process allows for a comprehensive assessment of a building's environmental impact and performance.
