1 are achieved . Several decentralised chilled water and extract air risers were designed to reduce the number of services that cross within the ceiling void of the passages .
The hotel moved away from the use of access control cards that are also used to keep the lights and air-conditioning on . The fan coil units are linked to thermal occupancy sensors as opposed to the motion detectors to ensure that the system remains active whilst guests are asleep .

PROJECT CHALLENGES AND SOLUTIONS Each component of this mixed-use development brought about its own set of challenges .
The residential apartments and hotel are both high-rise buildings with shallow ceiling void . Intricate co-ordination was required within the ceilings void . Several decentralised riser shafts were required to limit horizontal reticulation where possible .

The double volume car dealership had a significant amount of ‘ clear ’ glazing . Careful consideration was given to zoning the showroom , by keeping internal and perimeter zones on separate systems to achieve optimal comfort levels .
The correct selection of air terminals was also essential to ensure the correct air flow patterns with the considerable supply air volumes required .
The designs for the office and retail components were initially based on an open plan ‘ white box ’ design . As tenants came on board , their specific requirement had to be incorporated into the final fit out .
One of the challenges , as is with many residential apartments , is the availability of space for the outdoor condensing units . These units require ventilation in order for them to work at their peak efficiency and within the
