Car Park Ventilation Tips and Advice

"Cheap is not always cheerful"

In recent surveys of car park ventilation systems, some alarming shortcomings have been brought to light, particularly regarding the application of jet fan systems. There are a range of inadequacies ranging from basic poor design where substantial areas of the car park are devoid of ventilation by schemes originally designed to ventilate and control smoke but in reality are incapable of achieving this objective.

Jet fan systems have been around for several years and with over 95% of new installations being jet fan systems, people feel that it cannot be overly difficult to design these systems themselves and simply purchase the fans. Even systems designed and installed by some so called specialists however have revealed substantial shortcomings.

Simple misunderstanding of regulations and lack of knowledge of fan installations help explain how many of these problems arise. A recent investigation on one installation revealed two axial main extract fans installed in parallel, discharging into a common plenum. Whilst this was correct, they were also installed without non-return dampers fitted to the fans. This would mean should one of the installed fans fail, there would not only be a loss of performance in that fan but also a substantial reduction in the overall performance of the second fan caused by air short-circuiting through the failed fan.

There have been scenarios where the fire strategy has been accidently or purposely disregarded. Another example was an installation where the fire strategy required an advanced smoke control systems which could ensure that access to lobbies were kept free from smoke contamination in the occurrence of a fire in the car park. The reality was far from the requirements, with the most basic of smoke clearance systems being installed, no meeting the requirements at all. The most worrying aspect of this case is that between the consulting engineer, the building control officer and the client, none picked up on this and instead only recently was it identified by a fire officer and thus we were called in.

Why does this occur? The main motive is cost and the "design & build" culture in which the original objectives created by the architect, consulting engineer and fire engineer become lost, disregarded or forgotten against the background of Value Engineering.

This is not to say there is anything wrong with Value Engineering if the original objectives and strategy are met; however these can be easily forgotten and conveniently ignored when the contractor, encouraged and guided by a fervent pseudo-specialist who promises wonderful cost savings. When told by a specialist that the system will be “fully code compliant” and will meet all building regulations, it becomes very plausible and it may very well be the case. Conversely what has been overlooked is the initial enhanced design specification that was agreed at the opening design stage and against which relaxations were granted by building control on the requirement for sprinklers and the ventilation of access lobbies.

This can result in a range of problems. It could be several months later that the error may be identified. This leads to an expensive process of correcting the mistake, therefore rendering the once wonderful savings pointless as the initial savings become a drop in the ocean compared to costs of correction. Most importantly, not only could the handover of the building be delayed but if these shortcomings are not ultimately identified, the occupants and residents of the building could be put at considerable risk.

So how can we prevent this in the future? Through a fundamental understanding of how the original system design was developed and why. If apparent savings offered by alternative suppliers of specialists systems appear too good to be true, then the chances are they are and discussions with the companies involved in developing the original design should always be consulted in order to gain a full appreciation of the design requirements and objectives that must be obtained.

Advanced Smoke Group investing in the Future

"Youth will be a Key Driver to our Future Growth and Success"

It has been well publicised of the recent record highs in youth unemployment in the UK. With fewer companies providing fewer opportunities to the young, there is an extensive range of skills and potential available in the market that is being wasted at the moment.

The construction industry was one of the hardest hit sectors in the recession and in the UK is still struggling to regain sustained growth. With many organisations downsizing or defaulting, the Advanced Smoke Group are going against the trend and aiming for high growth for the future. A major feature of this high growth strategy is the employment of young workers who have the skills, determination and potential to be valuable members of the organisation. By working closely with the local University and Government skills funding agencies the Advanced Smoke Group are recruiting graduates and apprentices from the local community and providing them with the opportunity to gain further qualifications and valuable experience. The Advanced Smoke Group is a company specialising on smoke control and smoke ventilation systems in buildings, providing protected escape routes for residents and quick access for fire-fighters in the event of a fire.

Calvin Barnett who graduated in 2010 from the University of Leicester with a BA in Management and Marketing explained that even though he had achieved a first in his course, his lack of experience held him back from being able to get a marketing position in a company and there were very limited internship opportunities in the East Midlands.

Calvin explained, ‘The majority of firms I looked at wanted relevant experience as well as a degree but it seemed most work experience and internships seemed to be unpaid in London so I was in a Catch 22; I couldn’t afford to travel from the East Midlands to London daily for unpaid work or live in London unpaid and I was unable to find any experience opportunities in the town I live in to get a role in the career I wanted. If it was not for the Advanced Smoke Group providing me with the opportunity and taking me on as a marketing assistant, I do not know where I would be at the moment.’

Darren Wale, Technical Sales Manager for Advanced Smoke Group commented, ‘Many of the unemployed youth want to work, have the abilities and are eager to go; all they require is the opportunity. We want to help develop and grow these individuals and in turn they will help develop and grow the company.’

Young Guns



The young prospects all have an incredible work ethic and each showed real progress, contributing to some major developments in the company. Danish Ahmad was the first intern taken on by Advanced Smoke Group after completing his MSc in Advanced Electrical and Electronic Engineering from University of Leicester in 2009 and is now a full time employee of the company as systems developer following on from his internship where he was instrumental in developing and patenting a new product. Danish is now responsible for product design and development and states ‘Working at ASG is an honour; we have a very friendly environment with a very supportive team. This makes the workplace a very enjoyable place.’

Richard Brooks, General Manager of the Advanced Smoke Group states, ‘at the moment, downsizing and redundancies will not help local communities, organisations, industries or the economy. There needs to be investments into the future in order achieve sustainable growth and the youth have a lot of potential that will be valuable to the Group and provide a competitive advantage in the long term. This is why we are looking at developing bright and enthusiastic young prospects that have a lot to offer and provide them with training, hands on experience and real responsibility.’

Jade Brown, having recently finished her AS Level's is now an apprentice within the Advanced Smoke Group as an adminstration assistant and working towards gaining her level 2 NVQ in business administration. Jade says 'this apprenticeship gives me the opportunity to get hands on experience and training in the position. I am learning a lot and each day is different which has helped me gain a lot of different skills. The team is always there to support me and although I only started in November, everyone is really friendly and has made me feel at home straight away so I have thoroughly enjoyed my time here.'


Over the last 12 months the Advanced Smoke Group has taken on two graduate interns and an apprentice and are planning on taking on another graduate in Accounting in early 2012.

The ASG December Update

Tis' the season.....


As Christmas draws nearer and the year begins its conclusion, we are looking back at the year and some of the events that have shaped it. It has been a exciting year in what has been a pretty turbulent environment with some great new faces in the group, some unique patents and some very interesting projects.

Whilst it is nice to reminisce, there is a new year coming our way soon and we want to be ready for it. The Advanced Smoke Group is updating the look and feel of the website, which we be relaunching just before the new year with a modern, contemporary and simple design.

The navigation and theme is being redesigned to allow for easier use for all users and easier access to information and content on the site.

In preparation for this update, we are updating all of our other sites as well so that the theme is consistent throughout all outlets and ready for the new year, including our twitter and this blog. The new year is bringing with it a new look and feel for the Advanced Smoke Group and we couldn't be more excited to get it out there for all of you to check out.

We have also produced a publication looking in detail at the Pitfalls and Trends of Car Park Ventilation from the team here at ASG; providing important tips, guidelines, regulations and more.

For a free copy of the publication please email us at mail@advancedsmoke.co.uk with your contact details and address and we'll happily send it out in the post free of charge.

As a quick reminder to all those interested in the effective ventilation of Car Parks, we would like to remind you that ASG do run a free seminar (and lunch) at your own offices where our experts will present the ins and outs of smoke control and ventilation in Car Parks and how to optimise effectiveness and safety of systems. Simply call us on 0116 271 6861 or email us at mail@advancedsmoke.co.uk to arrange for a mutual acceptable date for the seminar to run.

We would like to thank you as well for checking the blog and keeping up to date with us; expect more and more material as time goes on and good luck with getting your Christmas preparations sorted. The new starter Calvin came up with a rather ingenious method of dealing with Christmas shopping when he told us; "I do all my Christmas shopping in the January sales then just hold onto it for 12 months....yeah it takes up space but as long as no one passes away and I don't split with my girlfriend then I'm quids in. And if we do split then I'll just store it till the next one comes along; it's win win really!"

You have to admire the dedication to forward planning.

Advanced Smoke Group Blackwall Tunnel Project: Largest AOV in Britain

Britain's Largest Automatic Opening Smoke Ventilator



Full Opened Blackwall Ventilator



Advanced Smoke Group finishes the largest Automatic Opening Ventilator in the UK at Blackwall Tunnel

Open Ventilator from the ground

The Northbound Blackwall tunnel constructed over 112 years ago and linking the boroughs of Tower Hamlets and Greenwich has seen a major refurbishment commissioned by Transport for London and awarded to Bam Nuttall. It is one of the busiest commuter roads in London, with over 50,000 vehicles driving through daily and is a vital link from one side of the Thames to the other.

The refurbishment involves a range of upgrades to various systems including drainage storage facilities, CCTV surveillance, fire and life safety systems, modern communication systems and a complete modernisation of the ventilation systems.

The Advanced Smoke Group, specialists in the design of smoke control systems for residential, retail and commercial premises were invited to tender by the consultants as one of only two companies who the consultants felt were qualified to undertake the project. The ventilation contract was awarded to the Advanced Smoke Group who designed, manufactured and installed the automatic opening ventilator for the existing ventilation shafts with dimensions of 8.5 metres in diameter and weight in excess of 8.2 tonnes, making it the largest in the UK.



One 'petal' of the Ventilator



The refurbishment required that a new ventilation system should be installed within the tunnel’s original ventilation shafts built in 1897 and it was decided that an opening roof would allow for the existing shafts to maintain their domed appearance. A mechanical ventilation system was created that would allow for the vents to open in case of an emergency in the tunnel. In the event of an incident or fire in the tunnel, the system will engage in a specific mode to allow for the extraction of smoke. Despite the vast size and weight of the smoke ventilator, the vents are capable of fully opening in sixty seconds.

The automatic smoke vents will help extract smoke and harmful gases from the tunnel in case of a fire, allowing firemen easier access to tackle any blaze.

Richard Brooks, General Manager for the Advanced Smoke Group commented that, “The Blackwall Tunnel project has been a great success and is a perfect example of the engineering expertise within the Advance Smoke Group.”

The system was designed and manufactured at the Advanced Smoke Group premises and Engineering Director for Advanced Smoke Group, Brian Lockton said “the fact we were able to build the Unit in Leicester in the UK, is a great achievement and an example of good British engineering.”
