The latest revision to the SCA Guidance on Smoke Control to Common Escape Routes in Apartment Buildings explained

Posted by Conor Logan on 08/12/15 12:00

The prevention of smoke spread through buildings is of critical importance.

The Smoke Control Association (SCA) has published Revision 2 to its ‘Guidance on Smoke Control to Common Escape Routes in Apartment Buildings (Flats and Maisonettes)’, which is available for download from www.feta.co.uk/smokecontrol. This revision became necessary largely owing to the ever increasing complexity in the design of buildings, and also to fall in line with amendments to the recently published BS 9991.

The recently updated BS 9991 and dual power supplies

Posted by Conor Logan on 01/12/15 12:00

A major update to BS 9991 “Fire Safety in the Design, Management and Use of Residential Buildings - Code of Practice” has been published by BSI and will come into effect on 31 December 2015. The Smoke Control Association, which I chair, played an instrumental role in this update.

Dual power supplies for smoke control systems are mandated. However this Standard now permits a lot more flexibility in their provision, which is very welcome given how often it is difficult to obtain them.

Webinar on the latest revision to the SCA Guidance on Smoke Control to Common Escape Routes in Apartment Buildings: Q&A

Posted by Conor Logan on 17/11/15 11:59

I received some excellent questions during the Q&A section during the recent webinar that I presented. Here you can see my answers to these questions, slightly edited for clarity.

The background to the webinar is provided on our recent blog. In this blog we refer to Revision 2 of ‘Guidance on Smoke Control to Common Escape Routes in Apartment Buildings (Flats and Maisonettes)’ from The Smoke Control Association (SCA), which is available for download from www.feta.co.uk/smokecontrol. This is an important revision to the Guidance.

There is also a recording of the webinar available.

EcoDesign: will new regulations prevent jet fans from being used in car park ventilation schemes altogether?

Posted by Conor Logan on 15/09/15 11:30

The EU EcoDesign Energy Efficiency Regulation for Fans 327/2011, which sets EcoDesign requirements for fans, is going through its final stages of preparation. It has raised an important issue that impacts on car park ventilation schemes.

BMS and smoke ventilation systems: what the control system must deliver

Posted by Conor Logan on 01/09/15 11:30

Part 3 - Opening up the Closed Protocol Debate

Control systems for smoke ventilation need to meet the demand for increasing complexity of modern building complexes, such as large-scale residential schemes or high-rise tower buildings. As a property owner or developer, when making your choice of a fire alarm control system for your building, you will have to decide between an HVAC/BMS control system or one specifically designed for smoke ventilation, and between open or closed protocol.

As you make your considerations, it is important to keep in mind the key requirements your control system has to meet.

BMS and smoke ventilation systems: reducing complexity in smoke ventilation systems controls

Posted by Conor Logan on 25/08/15 11:30

Part 2 - Why are there more complex demands these days?

The debate about the relative merits of open and closed control protocols is relatively recent. It has arisen because of the evolution of the smoke ventilation market towards more complex systems.

Part 1 - Selecting the right solution to control smoke ventilation systems

As a property owner or developer, when you have to select the best solution to control your building’s smoke ventilation system, you will most likely encounter the debate about the pros and cons of open and closed control protocols. This is the first in a series of articles that I hope will help you navigate the bewildering amount of information that is available on the subject.

I will start with the basics: what is a protocol and what does it mean when we say it is open or closed.

How to make the right cable selection for smoke control

Posted by Conor Logan on 11/08/15 11:30

When specifying a smoke control system, designers devote a lot of attention to choosing the right equipment - fans, vents and smoke barriers - for the job. They follow the standards set by EN 12101 for fans, vents and smoke barriers so that when the time comes, whatever the circumstances, the equipment will be capable of the job expected.

Electrical wiring – the vital link

But if this equipment relies on power supplies and signals to operate and continue operating during a fire, specifying the right equipment is not enough: designing and specifying the cabling linking the elements of the smoke control system requires just as much attention. Electrical wiring is the vital link between the control system and the equipment, the source of power and backbone of the smoke control system on which success or failure depends.

How to make car park ventilation schemes more energy-efficient

Posted by Conor Logan on 09/06/15 11:30

The Building Regulations do not advocate energy efficiency in car parks

The regulations applying to ventilation of car parks (at least in England and Wales) do not specifically advocate the conservation of energy, but surely they should do. It does not make sense that while buildings are subject to energy efficiency and low carbon emission targets driven by the Approved Document L of the Building Regulations, car park ventilation has no such requirement.

Moreover, an emphasis on lowest initial cost can mean that there is no consideration of the huge potential costs of running a ventilation system over the lifetime of a car park, and the CO2 emissions associated with this.
