Delivering air conditioning and ventilation for multiple commercial tenants at the base of a substantial inner-city apartment building calls for clever engineering to ensure that residents living above are not inconvenienced by machine noise.
In keeping with other new office projects in Workspace’s London portfolio, Taper Studios features exposed ceiling-mounted services including ducting, ventilation units and fan coil units.
The units are individually served by Daikin Sky Air systems of varying capacity, incorporating R32-based Bluevolution technology. Offices are ventilated by Daikin VAM total heat exchange units which are installed beneath the upstairs ceilings.
All these systems were installed by Daikin D1+ Partner, 360 Engineering as part of the project’s Category A fit-out. There are 11 units but the 12th and largest unit has two systems for its ground floor and four for its upper floor. Two other systems serve two communications rooms through wall mounted indoor units.
Katie Floyd, sales director at 360 Engineering, says the challenge was to locate the outdoor units as close to the offices as possible, but without creating an ongoing disturbance – or spoil the outlook – for the residents.
She says: “The solution was to install half the outdoor units at high level in the car park, which is naturally ventilated. Ideally, all the units would have been there, but there was concern that the car park might become unpleasantly hot from discharged heat when all the units were at maximum output in cooling mode. So, the other units are out of sight in an adjacent external walkway.”
Supply ventilation for the VAM units is taken from the courtyard garden, with some complex ductwork to reach the offices.
Kahroon Tanvir, Senior Product Manager for Workspace says: “While designs for the internal services were not especially constrained by height, the choice of Daikin systems was helped by the fact that its indoor units were 52mm shallower than competitors'. It’s not a big difference, but we believe it is important to give tenants as much headroom as possible. Even just 52mm adds to the feeling of spaciousness.”
