Adexsi delivers versatile ventilation system for Walkie Talkie building
Adexsi’s Veriflow system is playing a key role in keeping the ‘Walkie Talkie’ building at 20 Fenchurch Street in London cool and ventilated. The system will also provide smoke ventilation in the event of a fire.
The Veriflow system comprises a series of dampers at high and low level operating discreetly behind the building’s cladding fins and external/internal louvre systems. The dampers were installed inside the curtain walling, which was designed by cladding specialist Josef Gartner. They operate in a gap of just 180 mm.
The damper controls are linked to the building’s BEMS, which ensures the building is fully modulating and that the appropriate number of high- and low-level vents are open to meet ventilation requirements at all times of the day and night.
Rob Davies, UK director with Adexsi, says, ‘We are delighted to be playing such an important role in the successful operation of a true London Landmark. This is also part of a growing trend to engineer systems that can operate as both day-to-day ventilation and as smoke extractors in the event of a fire.
‘We are seeing increasing demand for this kind of solution as it allows end users to maximise the payback on their investment by meeting safety and comfort requirements with one system. However, to do this properly requires close collaboration between the ventilation specialists and the rest of the building’s design team.’
