Testing and commissioning smoke control systems: what to watch out for

Posted by Conor Logan on 04/10/16 12:00

As a designer, specifier or building owner, you will want to be sure that your smoke ventilation system will provide fire safety in all situations.

Design on paper versus the practical realities of construction

It is all very easy to design on paper a system that provides a certain duty and airflow, but this often does not take into consideration the practical aspects of constructing a building. There are some potential pitfalls to avoid to ensure that your smoke shaft or pressurisation system will function as intended.

The impact of door size on smoke control design

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

One of the biggest challenges in the design of smoke control and pressurisation systems currently is the relatively recent trend towards installing full height doors which extend all the way to the underside of the ceiling, and/or very wide single leaf doors.

While there are no regulations governing the height of the doors which separate corridors, lobbies and stairs in a commercial or residential building, from a smoke ventilation point of view, full height or “oversize” doors can be problematic.

What are the options for smoke control when changing the use of a building?

Posted by Paul Compton on 09/02/16 12:00

Owing to the different types of occupancy patterns, the Building Regulations rightly provide differing guidance for commercial and residential buildings.

So, when a building changes use, assuming that the developer is not prepared to alter the layout of the stair, it is likely that Building Control will insist on a fire engineered solution leading to the highest degree of protection in terms of the smoke control system

Questions and answers from Paul Compton's 'Pressurisation systems in residential and commercial buildings' webinar

Posted by Paul Compton on 17/12/13 11:30

At Colt’s recent oversubscribed CPD accredited pressurisation webinar, we received some interesting questions in the Q&A session at the end. I’d like to share some of them. They are edited to make the questions clearer and to reduce my ramblings.

Q: Do all buildings that operate a stay put policy have to have a Class A pressurisation systems?

A: No, if you have a residential building then certainly in the UK that would normally have a stay put policy and, if you choose to have pressurisation, then it would be designed as a Class A system. In a residential building in theUKyou are permitted AOV or shaft systems instead so the fact that you have a stay put policy in a residential building doesn’t mean that you need pressurisation.

Questions and answers from Paul Compton's pressurisation webinar

Posted by Paul Compton on 23/04/13 10:11

First of all a big thank you to those who attended my webinar last Friday on 'Pressurisation Systems in residential and commercial buildings'. If you missed it or would like to watch it again a recorded version is available here. Many questions were asked after the presentation and I decided to post the most interesting ones up here for everybody’s benefit.

Could a "pressure relief damper" or "air release" be fitted to an external window/fixed pane of glass at the end of a corridor?

The publication of BS 9999 and BS 9991 has been a breath of fresh air in some ways, but of course not everything new is perfect.
