Powrmatic has supplied a combination of single and double flap Skyvent ventilators to provide natural and smoke ventilation at the BP2 building in Canary Wharf, East London. Each of the 13 BS-EN 12101 ventilators was installed by Air Design Systems Ltd onto existing upstands with insulated lids and bodies and polyester powdered coated to RAL 9007 matt.
The BP2 office building was constructed on reclaimed land at the eastern gateway to the Canary Wharf estate and comprises 14 stories above ground, plus three basement levels. The building’s design places strong emphasis on energy efficient performance, so this was an important criterion in the selection of ventilators.
“We selected Powrmatic Skyvent ventilators for this project due to their extremely low air permeability and energy saving characteristics,” explained ADS Director Alan Clare. “Each vent is controlled by pneumatic actuators which open the vents to 140 degrees to allow for a far greater free area when open”.
Air Design Systems Ltd provided a full design and build package for the client. This included installation of local control panels and electrical wiring, as well as micro-switches to allow a positive signal that each ventilator is fully open prior to the pressurisation system starting up. Air Design Systems Ltd also supplied and installed numerous continuous louvres to the plant wells that rise through the building and terminate at roof level.
Skyvent ventilators are designed for both smoke and natural ventilation and are available in single and twin flap versions to suit the needs of each project. They can be installed on upstands, roof sheeting and into glazing systems. They feature very low air leakage when closed, and are weatherproof when closed, as tested to BS Parts 1 & 2. Insulated options can achieve U-values as low as 0.17W/m2/K.
Skyvent ventilators are available with optional aluminium (single skin and insulated), polycarbonate or glazed lids in polyester powder paint finishes to any standard BS or RAL colour. A full range of accessories is available including bird guards, security guards and insect mesh.
