Underfloor air conditioning was specified by M&E Consultant, MTT for the refurbishment and is installed over 11,000 sq. ft. of Grade – A office accommodation on floors 1-4. With underfloor systems, fully conditioned air is fed into the plenum by zonal downflow units (CAM), which is then supplied into the workspace via fan terminal units (Fantile) recessed into the floor.
Systems can be either chilled water or direct expansion, configured with either floor level or high-level return and they can easily integrate with passive or other ventilation systems. Testament to the design, the building was awarded BREEAM Very Good and shortlisted for the New London Architecture Awards 2018 – Office’s category.
CAM-V direct expansion (DX) system
The system installed at 6 Warwick Street is a CAM-V direct expansion (DX) system, with underfloor supply air and return air at a high level. The high-level return air option can offer greater flexibility for positioning Fantiles for future and speculative tenants as there is no air segregation baffle dividing the underfloor plenum.
The fourth floor with its striking, angled floor-to-ceiling windows is the first to be occupied, with the entire floor leased by pulp and paper specialists, Pulp Mill Trading Ltd.
Supply and installation of new equipment
Working for Maris Interiors, 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 a number of return air grilles and sound attenuator boxes to boost return airflow from the acellularized space, and five FlexTouch wall controllers permitting easy user control of airflow and temperature. All programming and setting to work of the new equipment was carried out and the new workspace was ready for occupation by Pulp Mill Trading in July.
