The development also includes 193 high-specification apartments, restaurants and other units.
The office accommodation is in three glass-clad storeys at the top of the building. Exposed castellated steel beams beneath the concrete floor labs create an impressive architectural feature but prevent the use of ordinary air-conditioning systems.
Instead, the Hiross system is installed in raised access floors 250 to 300 mm deep. Within the floor void is a duct-free air-conditioning and ventilation system, plus all cable and power-distribution services.
Each floor is divided into separate air-conditioning zones, each supplied with cooled or heated air by a conditioned-air module (CAM). The floor void is split into supply- and return-air plena using baffles that can be easily moved.
Supply air is drawn into the occupied space by fan-assisted terminal units recessed into the floor. Grilles in the floor above the return-air plena enable air to return to the CAM.
Since the grilles are not restricted by duct or pipe connections, they are easily interchangeable with other floor panels as required.
