Sertus were approached to provide a mechanical smoke ventilation system to provide both smoke ventilation to clear the car park of smoke in the case of a fire, and also environmental ventilation to keep the level of carbon monoxide (CO) and nitrogen oxides (NOx) within the car park to a safe level during the day-to-day running of the car park.

With all car park ventilation systems, each system provides a unique challenge because every car park layout is unique. In this case, the single-level car park had a high length to width ratio which meant it was challenging to design a ventilation system that had no potential dead spots which could result in the build-up of harmful gases.

To overcome the challenge of dead spots, impulse fans were positioned to create disturbance and turbulence to ensure that smoke and gases could be pushed back to the extract point.

As a result, the system fully meets all requirements of BS 7346-7:2006 which have been proven by Computational Fluid Dynamic (CFD) modelling and analysis.
