Powrmatic has supplied 73 Roof Opensky smoke ventilators to the new IKEA store in Dublin. Specified and installed by Air Design Systems Ltd, the installation is providing full smoke ventilation to five separate areas within the store.
The market hall area required a powered extract system including 10 duct runs with grilles, extract fans and external louvres; replacement air was provided through openable wall louvres.
The second area is the show room and café which were naturally ventilated by louvred ventilators and split into zones using a fixed smoke curtain. A similar approach was taken with the self-serve warehouse and checkout area, which was also naturally ventilated using louvred ventilators and fixed smoke curtains. Polycarbonate blades are used on the louvred ventilators to allow natural light to enter the spaces.
Additionally, the escape staircases were ventilated using louvred ventilators at the head of the stairs and a local control panel with an emergency break glass.
“We were involved from the very early in the design stages of the project, using our knowledge and experience of installations within other IKEA stores and warehouses to engineer a suitable, cost-effective solution”
“Within these works we have had to include for three separate main control panels, all electrical wiring run in fire-protected cable, local control panels with emergency break glasses and a mimic control panel linking all smoke ventilation zones. We also provided rain sensors, roof access hatches, and head of lift shaft cowls”
Due to the success of the project, there was a requirement within a year of opening to extend the warehouse area. Air Design Systems Ltd was awarded the sub-contract to extend the system into the new space and link back to the existing control system. In total, a further 14 Powrmatic ventilators were installed in the warehouse roof & walls and at the head of the two additional emergency staircases.
Powrmatic’s Roof Opensky ventilators are attractive, low profile units that have been specifically designed for both smoke and heat exhaust and natural ventilation applications. Opensky can be roof or wall mounted for exhaust or inlet and can be supplied with a hinged base for use as an access hatch. They are tested for use as smoke ventilators to BS EN 12101-2.
