System
Displacement Ventilation with Fantile

2011 New Build

Mixed use, eight storey building constructed in 2008, consisting of basement level residential units, retail space on the ground floor and six floors of speculative office space.  The 2,000 sq. m development situated in the St Luke’s conservation area features an award winning Terre Doree brick façade, which not only offers a striking modern look due to the cream colour and the intricate style the brick perforations created, but also permits enhanced natural ventilation due to the openable panels on the inside wall.

The building is served by two large interlocking AHU’s via supply and extract ductwork in vertical risers and the office areas on floors 1 – 6 each have approximately 12 TU4 Fantiles which introduce supply air into the workspace.  Due to the addition of fan terminals the underfloor pressure needs to be maintained at 18-20Pa.  This is regulated by an AHU modulating bypass damper controlled by a pressure sensor in the main riser supply duct.  The building is awarded BREEAM Excellent status.
