Smoke Modelling (CFD)

Fire and Smoke Modelling (CFD)

Understanding fire and smoke modelling

Fire and smoke modelling helps you understand how fire and smoke could behave in your building. This approach is used to check if your fire safety design will work as intended or if you need a more creative solution to meet specific safety goals.


Using advanced computer software, such as Computational Fluid Dynamics (CFD), we create a virtual model of your building. We then simulate fire and smoke movement in different scenarios. This gives you clear evidence of how fires could develop and spread, including how smoke will move, temperatures reached, and how people will be affected.


Why does this matter? Many projects have design features or layouts that do not fit standard guidance. Sometimes you want to achieve open-plan spaces, unique atrium designs, or need to support alternative evacuation routes. In these cases, fire and smoke modelling can give you the proof you need to justify your approach to Building Control or the fire authority. It also helps reduce risks, improve safety for occupants, and can save time and money by preventing costly redesigns or delays.


Why fire and smoke modelling is necessary

  • Meets Building Regulations and fire safety standards

  • Supports non-standard designs with clear evidence

  • Reduces risk and improves safety for occupants and first responders

  • Can enable cost savings by avoiding unnecessary fire safety measures

  • Gives you confidence that your fire strategy works in practice

Our Fire and Smoke Modelling (CFD) process

01

Initial consultation
Share your project details with our fire engineering team so we can understand your aims and any design challenges.

02

Data gathering and model setup
We gather architectural plans, building use information, and any existing fire strategy documents. Our specialists then build a digital model of your building using CFD software.

03

Fire and smoke simulation
We run simulations for agreed scenarios, examining how fires and smoke could spread and identifying areas of risk.

04

Results analysis and reporting
We review the outcomes, highlight key findings, and prepare clear reports (including visuals) for submission to Building Control or the fire authority.

05

Ongoing advice and support
Our team stays involved through the design and approval stages, helping to answer questions and advise on any follow-up actions.

Dan at enevo has completed for us SBEM Calculations and EPC Certificates for 6 commercial units on an industrial estate. The cost of the works was very competitive and the service we received was second to none. With very limited time to get these works completed Dan worked round the clock (and into his annual leave!!) to ensure that our completion date was achieved with very little notice. Would highly recommend!
