AET Flexible Space undertook the manufacture and supply of underfloor air conditioning systems for the refurbishment of Hammersley House at 6 Warwick Street in London's West End. The six-floor property provides retail and office accommodation and has been fully redeveloped by its owners, Royal London Asset Management.
The AET system installed is a CAM-V direct expansion (DX) system, with underfloor supply air and return air at high level. The high level return option can offer greater flexibility for positioning fantiles for future and speculative tenants as there is no air segregation baffle dividing the underfloor plenum.
AET engineers carried out an initial system survey and subsequently supplied and installed new equipment to cater to the new tenant layout. This included relocating and supplying additional fantiles and associated cabling and commissioning, supplying return air grilles and sound attenuator boxes and five FlexTouch wall controllers.
Fully conditioned air is fed into the plenum by zonal downflow units (CAM), and then supplied into the workplace via fan terminal units (fantiles) recessed into the floor. The system can be either chilled water or direct expansion, configured with either floor level or high level return, and they can be easily integrated with passive or other ventilation systems.
The building was awarded a BREEAM 'Very Good' and shortlisted for the New London Architecture Awards 2018, Offices category.
