Versatile FlowBar chosen for special application in new Bloomberg HQ

A new European headquarters for the global business and financial information leader, Bloomberg, opened in October 2017. Located between the Bank of England and St. Paul’s Cathedral, the new site occupies 1.1 million sq feet and houses Bloomberg’s 4,000 London-based employees. Both Air Diffusion and Actionair worked on this project, providing solutions for the building’s ventilation and fire safety needs.

Project HVAC contractor, Hotchkiss, approached Air Diffusion after SWECO specified the chic and versatile FlowBar diffusers for the project. We were able to adapt the flexible design of our air distribution terminal for a special application to run inside ceiling lighting channels, in order to satisfy the design requirements of project architects, Foster & Partners.

Most of the diffusers were manufactured with flangeless border type 11 to allow the FlowBar to be fixed into the ceiling channels. Border 11 is commonly used in thin plaster applications where a discreet and clean finish is required. The shallow frame has allowed the diffusers to be securely fixed into the ceiling of the new building and plastered over.


For other areas of the building, a unique design of FlowBar was manufactured with border type “12”. This combines border 11 and border 22 with one type used on each side of the diffuser. The side with border type 11 is flangeless, enabling the ceiling’s lighting channel to run seamlessly alongside the diffuser.

Air Diffusion also supplied a variety of fixed linear bar grilles and fixed pattern ceiling swirls - standard, yet attractive diffusers that are helping to provide the open, spacious buildings with an appropriate and sufficient level of air distribution.

The building has been awarded an “outstanding” rating from BREEAM, which recognises the sustainability of buildings. We are proud to have been able to add our expert services within the prestigious new Bloomberg headquarters by providing products which aid the day-to-day comfort of its occupants in a sustainable way.
