Do you need natural or mechanical smoke shafts?

Posted by Paul Compton on 21/06/16 12:00

Smoke shafts in multi-storey buildings take up potentially valuable space, so keeping the shafts as small as possible is beneficial and has led to mechanical shafts becoming a popular choice.

But are they always the best choice? We look at some of the issues.

How to improve productivity when the temperature rises

Posted by Paul Langford on 14/06/16 12:02

This Colt advert first featured in the Financial Times
almost 40 years ago, and still rings true today!

As the temperature rises during the summer months, it is important to asses your productivity levels. If your factory is too hot, then you will almost certainly suffer losses in production, as well as a whole host of other issues.

However, there is a solution.

How to select the correct air filters for your HVAC system

Posted by Laurence Cockman on 07/06/16 12:22

Air filters are used in heating, ventilating and air conditioning (HVAC) systems to improve air quality in indoor working environments. They can also serve to protect the HVAC equipment.

Pollutants can originate from a source outside or inside the building. In this blog I will discuss pollutants which originate outside of the building.

Car Park Ventilation: How much attenuation should a design include?

Posted by Conor Logan on 31/05/16 12:00

As a designer working on a car park project, there are important considerations you will need to make about ventilation to ensure good air quality. Approved Document F (ADF) stipulates that sufficient ventilation must be provided to enclosed car parks to avoid an excessive build up of carbon monoxide (CO).

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?

Feeling the heat? Upgrade your existing ventilation system!

Posted by Andrew Wright on 17/05/16 12:00

As a factory manager, you may find that in spite of keeping your mechanical ventilation system in perfect condition, the temperature in your plant is increasing. Over the years, the use of your building may have changed, as with the introduction of lean manufacturing practices, there may be a higher density of production machinery with consequent higher heat load in some areas of your facility. This means that the mechanical ventilation system as it was originally designed and installed no longer meets your requirements.

Not all “Class A” weather louvres offer the same rain defence

Posted by Paul Compton on 10/05/16 12:00

A common misconception is that all “Class A” weather louvres, as defined in EN 13030, offer the same level of rain defence and can be taken as equal.

This is not the case. Let me explain.

Consider the ancillaries when specifying weather louvres

Posted by Paul Compton on 03/05/16 12:00

When specifying weather louvres, it is important to consider an often neglected part of the louvre specification: the ancillaries. I have previously written about the key considerations when specifying louvres, which guides you through some important areas when specifying louvre. However, once these requirements have been met, you must also consider the following:

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 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.

How to avoid overheating in common corridors of residential buildings

Posted by Paul Compton on 05/04/16 12:00

The quest for energy efficiency has led to very good insulation in residential buildings. While this is very good for the environment and electricity bills, it is having unintended consequences on stair lobbies, corridors and entrance halls, which tend to overheat. This results in unpleasant conditions for residents and possible issues maintaining cold water supply temperatures.

How to select modulating controls when specifying glass louvred ventilators

Posted by Graeme Clark on 22/03/16 12:00

Following our recent article on the “Top three considerations when specifying glass louvred ventilators” we have been inundated with questions about modulating controls. Clearly this is a topic that resonates with many in the industry, and in this article we aim to provide some guidance on how to modulate louvred window ventilators.

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:
