Smoke control in shopping centres: design approaches and challenges

Posted by Conor Logan on 08/06/21 10:00

In retail premises such as shopping centres, the Building Regulations have a strong emphasis on the provision of life safety systems such as smoke control.

A well-designed smoke control system should be able to maintain smoke free escape conditions at low level to allow the building to be evacuated with minimum risk of smoke inhalation, injury or death.

Smoke control requirements in educational buildings: what you need to know.

Posted by Conor Logan on 26/05/21 10:00

While smoke control is vital in any type of public building where people gather, it is perhaps even more so in schools and other buildings the more vulnerable members of society assemble. In this blog, we will cover the regulations around smoke control requirements in educational buildings and share some design considerations that are vital when configuring fire safety systems for buildings with children as the main users.

7 reasons why you shouldn't use HVAC control systems for smoke ventilation

Posted by Conor Logan on 02/06/20 10:00

Smoke ventilation systems today require sophisticated control systems with highly complex sequences of operation. HVAC control systems could be seen as a viable solution, as they can be extremely flexible and offer a high degree of programmability. However, while they may be adequate for simple applications, there are a number of issues that mean they do not deliver on all the functionalities needed for more complex schemes.

Here are 7 reasons why:

What type of vent do you need for a smoke shaft system?

Posted by Paul Compton on 05/07/16 12:00

When designing smoke shaft systems, which type of vent do you need?

Types 

The choice is short and sweet as there are only 3 basic types available:

  • A smoke damper mounted behind a grille
  • A bottom hung motorised flap
  • A motorised fire door.

Seems a simple choice, but there’s more to it than aesthetics, as you’ll see.

Designing a smoke control system to achieve extended travel distances

Posted by Paul Compton on 28/06/16 12:00

When designing ventilation schemes for common corridors in residential developments, it is now possible to go beyond simply creating a building design that is compliant, by allowing corridors to be extended beyond the travel distances permitted in ADB.

When is smoke control needed in a car park?

Posted by Conor Logan on 24/05/16 12:00

Let me make it clear. I’m talking here about systems providing smoke control, not just smoke clearance as recommended in Building Regulations. These systems are much more complex and costly than compliant smoke clearance systems, so why would anyone choose to use them?

Why are actuated windows a bad idea for smoke control systems?

Posted by Conor Logan on 26/04/16 12:00

You may think that fitting an actuator on a window instead of using a smoke ventilator will make a cost effective solution for smoke and natural ventilation, but unfortunately it is not that simple.

Here are some of the ways in which a window/actuator combination can be a poor substitute for a smoke ventilator:

The top three considerations when specifying glass louvred ventilators

Posted by Graeme Clark on 08/03/16 12:00

Glass louvred ventilators, or louvred window ventilators as they are commonly known, are becoming increasingly popular for use in natural and smoke ventilation systems. There are several suppliers on the market, offering products that vary widely in terms of performance and controls. How can you make sure you will get exactly what you need when specifying or purchasing one of these ventilators?

There are three critical considerations you should make when preparing to specify a glass louvred ventilator:
