Smoke Ventilation SE Controls offers a comprehensive range of natural and powered Smoke Heat and Exhaust Ventilation systems (SHEV) suitable for any size and type of building. Our systems are designed to facilitate the safe escape of occupants in the event of a fire and to enable the fire to be fought in its early stages.
Environmental Ventilation Environmental or Natural ventilation improves indoor environments, reduces CO2 emissions and is cost efficient. Adaptive environmental ventilation systems are less costly than traditional HVAC systems, being cheaper to install, run and maintain. Adaptive natural ventilation is leading the way for a sustainable future.
Façade Automation Automatically opening windows uses hardware, known as actuators or rotary handles, that fit directly onto the window system which push and pull the window open and closed, instead of operating the window manually.
Remote Services Using 4G communications technology and intelligent algorithms we can analyse the data collected from our systems placed within buildings to continually improve operating efficiencies and report back on the findings of our research to help you better understand your buildings.
Further technical information is available in the BPi download library or on the SE Controls website.
Walthamstow Residential Development
Smoke and environmental ventilation from SE Controls for Walthamstow residential development.
A major residential development by Taylor Wimpey in Walthamstow, East London, is using combined environmental ventilation and smoke control system from SE Controls to help keep residents both comfortable and safe.
As a key part of the ongoing planned regeneration of the Blackhorse Lane area, the Eclipse development provides more than 400 one, two and three bedroom apartments, as well as incorporating a proportion of affordable housing within the design.
Eclipse is split into two construction phases with each comprising of six residential blocks that are joined together to form a single building. Each six-storey block incorporates a dedicated hybrid smoke control and ventilation system, which was designed and installed by SE Controls.
In normal operation, the hybrid system maintains comfortable temperatures within the corridors and avoids overheating due to ceiling mounted heating pipework, while providing fresh air movement through the building.
To achieve this, SE Controls installed ‘enviro-fans’ in the ceiling plenum on every floor, which are activated by temperature sensors and draw warm air from the corridors, into the building’s smoke shaft before being vented.
The mechanically vented smoke control system utilises roof mounted duty and standby fan sets, which are linked to smoke shafts in each of the residential blocks. Every corridor is fitted with a SHEVTEC smoke shaft damper, which opens in the event of a fire, allowing the fans to remove smoke from the fire corridor into the smoke shaft to keep escape routes and stairs clear of smoke.
SHEVTEC control panels are installed on every floor to manage the automatic operation of the smoke control system, while tamper proof manual control points enable the fire service to reset the system after testing or actuation and also prevent any accidental activation.
Due to the building’s design, the roof mounted duty and stand-by smoke fan sets had to be concealed and located away from terraced areas to meet this requirement, SE Controls created a dedicated solution that would also allow them to be accessible for maintenance and servicing in accordance with the specified schedule for compliance.
In addition to using fire rated ducting, which allowed the smoke shaft to be offset at roof level, SE Controls Contracts Manager, Dave Furneau developed a fan ‘cassette’ solution, which enabled the fans to be concealed within the shaft, yet also allows them to slide out on integrated load bearing runners.
A key benefit of this approach, in residential situations is that it provides unrestricted access for service engineers, which minimises downtime and reduced potential risk exposure for the building. If necessary, a fan can be replaced within a turnaround time of 1 hour.
Paul Denyer SE Controls Project Manager for the Eclipse development, explained: “We engineered a dedicated fully compliant system for this project, as the design of the building and the specification presented some unique challenges in the way the system functioned. While life safety is the dominant aspect of the system, the need for environmental ventilation and corridor cooling enabled us to utilise the smoke shafts as part of the solution, enabling us to create an effective and safe hybrid solution.”
Compliance is compulsory not optional.
An article covering everything you need to know regarding compliance for the façade industry. By Martin Oates – Director of Global Sales.
It is now two years since the tragedy of Grenfell Tower and fire safety rightly remains the primary focus for the construction industry. This was further reinforced in June with the publication of the government’s proposals for reform of the building safety regulatory system, as part of the Building a Safer future initiative.
The Independent Review of Building Regulations and Fire Safety final report was presented to Parliament in May 2018, with many recommendations already being addressed, or existing policies better policed. This was followed in December with the Building a Safer Future Implementation plan, which defined the key areas requiring attention, namely ‘making buildings safe’ and ‘overhauling the regulatory system’.
The importance of these documents and other regulations to the façade and envelope industries cannot be overstated. Compliance is an absolute requirement, especially when designing, testing, fabricating and installing systems that are used for smoke control, which protect lives by keeping escape routes clear of smoke.
Fire and building safety regulations are by necessity among the most demanding and stringent parts of building design. While increased focus is now being placed on improving them even further, most of the key product legislation was already in place in advance of the Grenfell fire.
In June 2013 the Construction Products Regulations (CPR) was written into UK law, mandating into UK construction the CE certification of construction products that have a harmonised European Norm (hEN). Of course, life safety smoke ventilation products also fall into a key category, namely the EN12101 family of European standards.
The relevant parts of the EN12101 family that predominantly affect the façade industry are EN12101-2:2003, which governs smoke vents or SHEV’s and EN12101-10:2005, power supplies for smoke ventilation.
Compliance to part 10 is easily policed as the entire control panel that contains the power supply is tested at an accredited test facility, to the annexes of the standard. A CE compliance label is applied to the product and a Declaration of Performance (DoP) provided as proof of compliance to the CPR. The use of ‘CE marked power supplies’ for the power supply unit within a control panel however, is not enough as the entire panel has to be tested as a whole.
For EN12101-2 (SHEV’s) this is a more complex affair, as there are two constituent parts, the actuator and the ventilator itself. To comply, both products must be tested together to all annexes of the standard, as a single unit at an independent accredited test facility.
In addition, the vent must be manufactured under a third party audited FPC scheme, with the actuator either installed within this process, or on site. If it is the latter, an audited process to ensure the detail is identical to how it was tested is also required. Once again, the only proof of compliance is the CE labelling on the product and the issuing of a DoP.
Comprehending these standards and their application, as well as their legality, has been somewhat confused within our sector, mainly due to a lack of awareness and inconsistent advice.
This is improving as the responsibility and impact of non-compliance and poor procurement are becoming clearer. Non-compliance does, unfortunately, still exist and in many cases without anyone knowing until there is an incident or when proof is requested.
We are seeing a huge increase in the correct policing of compliance via approved inspectors, such as NHBC and LABC. Proof of compliance (the DoP) is being requested, with delays ensuing, often resulting in the activation of LAD clauses. Non-compliant windows used as SHEV’s are being removed on a regular basis with the façade contractor often having to replace them under impossible timescales.
SE Controls systems are of course tested and certified to EN12101-10, with a DoP produced. We also have an unrivalled portfolio of tests to EN12101-2 covering twenty-seven façade system companies, in addition to a national network of audited trade fabricators and installers. As the DoP is produced by SE Controls, this removes the responsibility for placing it onto the market from the façade contractor.
SE Controls remains at the forefront of the industry via committee and regulation activity, design capability, system installation competency, preventative maintenance and product compliance.
We are present at both European and UK levels through our direct involvement in product standards and fire safety committees, ensuring that we are helping guide the industry and able to advise any client at any level or stage in the process.
One of the key outcomes of our activity in the UK is the implementation of the Smoke Control Association’s (SCA) third party audited IFC SDI 19 scheme for life safety smoke ventilation systems, which covers all aspects from design, through to product compliance and installation competency.
SE Controls was the first company to gain this accreditation, which should be a pre-requisite for procurers of life safety smoke ventilation systems. It is now a condition of membership for any company applying to join the SCA.
Additional initiatives include involvement in the updating of Approved Document B post the Dame Judith Hackitt independent review, and an updated clarification document of best practice for smoke ventilation within the high-rise residential sector.
As a direct consequence of our involvement with the regulatory environment and our complete commitment to compliance, we receive a wide range of questions from the façade industry. Some of the most common relate to regulations and product standards, so we’ve provided clarification on several FAQs below.
It is possible to install the actuators on site and certify, providing an audited process is followed, as many applications do not lend themselves to protecting the products in transport or on site. This is allowed within the CPR.
The current harmonised EN12101-2 version is 2003. 2017 has not been harmonised by Europe yet so is not declarable under the CPR.
A tested actuator installed to a tested vent cannot be compliant or certified, as they were not tested together. It is not ‘fit for purpose’ as a life safety product and responsibility of approving such a solution is not the responsibility of the Approving Authority. Responsibility lies with the company that placed it onto the market.
prEN12101-9 (smoke and heat controls systems) is a provisional EN that is not harmonised, therefore not applicable under the CPR until it is harmonised.
CE marking and EN compliance will be with us for at least two years regardless of the political landscape.
CE marking is merely a vehicle for certification, so even if the UK adopt a different scheme, the tests that were carried out to comply to EN will still be valid for the new scheme (such as a UK mark for example)
