Dynamic Simulation and Thermal Modelling

What is Dynamic Simulation and Thermal Modelling?

Using whole building simulation programs, Dynamic Simulation Modelling (DSM) is used to undertake Thermal Modelling, calculate energy consumption, heat gains and losses, produce daylight calculations and assess the environmental performance of a building.

Simulation programs are used to produce a 3D model of the building using actual weather and solar data for the building’s specific location which is orientation accurate. A multitude of details are input into the software including, but not limited to, building fabric, mechanical and electrical services, zonal activities, occupancy periods and HVAC schedules. Yearlong simulations are then undertaken on a room-by-room basis to calculate the building performance which can then be used for the analysis of the building.

For Thermal Modelling, this provides the ability to compare the simulated results against project specific criteria designed to limit overheating. Thermal Modelling is used to assess both commercial and residential developments.

Whilst SAP and SBEM are great tools for carrying out simulations to show compliance with Part L, it is very limited in its use. DSM allows for greater analysis on solar gains, energy consumption, gains and losses, the effects of shading from external sources and the overall ability to input details on a more project specific basis.


Dynamic Simulation and Thermal Modelling Services we offer:

  • TM52: Commercial Buildings (non-domestic)
  • TM59: Residential Buildings
  • Approved Document Part O Compliance DSM Reports
  • TM54: Operational Energy Performance of Buildings and the Design Stage (for both commercial and residential buildings)
  • TM49: Design Summer Years for London (residential only)
  • BB1010: specifically for schools

What are the benefits of DSM and what can it be used for?

Thermal Modelling can be used to produce and accurately investigate the following building characteristics:

  • Design Stage & As Built Stage Part L Calculations/BRUKL Reports
  • Energy Performance Certificates
  • Predicted Energy Use/CO2 Emissions
  • Thermal Performance
  • Overheating Analysis and Thermal Comfort for BREEAM Projects
  • Daylight Calculations/Sunlight Assessments
  • Renewable Technology Studies
  • Energy Statements
  • Calculate Heating Loads and Cooling Loads

Part O: Overheating

The UK government recently introduced Part O to the building regulations which focuses on overheating in residential dwellings. DSM and Thermal Modelling can be used to demonstrate compliance with the new regulations which come into force in June 2022.

Under the regulations, you are required to make reasonable provision to:

  1. Limit unwanted solar gains in summer
  2. Provide an adequate means to remove heat from the indoor environment

Compliance with this can be demonstrated with The Simplified Method set out in Section 1 of Approved Document O. If this fails, you will be required to carry out The Dynamic Thermal Modelling Method as set out in Section 2 of Approved Document O. This is a service we can provide for you.

Our Thermal Modelling Process

  • Review plans and specification
  • Produce accurate 3D building model of the building using industry leading DSM software
  • Carry out detailed analysis by running various simulations over a period of time
  • Provide accurate results and guidance on the project specific area of analysis
  • Supply reports/calculations to meet project deadlines

We can help you...

Save money

We will reduce your build costs by adopting the 'Fabric First' philosophy to remove the need for expensive renewable technologies. We carry out a complimentary specification review on every single project to see where we can reduce your costs.

Reduce risk

All our compliance services come with a 100% pass guarantee. We will never charge you for assessments that don't pass. We will always provide free guidance to achieve a pass in the cheapest way possible.

Reduce red tape

We operate a common sense approach to building compliance. Our team comes from a background in volume house building, Architecture and Engineering. We understand all the time, cost and hassle constraints involved in construction.

Save time

We can provide a 24 hour turnaround on services when required. Also, we will produce your new build EPCs on the same day as receiving the air test result.

"C80 are very helpful, efficient and professional with fantastic turnaround times. We wouldn't hesitate to recommend them"
