DESIGN SPECIFICATIONS Each component of the mixed-use development ( retail , office , residential , car dealership and hotel ), had specific HVAC requirements .
The residential block and office required a decentralised HVAC system , and the main addition of individual billing was a priority for this area .
The hotel ’ s main focus was stringent humidity and climate control . The acoustic treatment was also high on the agenda .
The retail portion required standalone systems for individual tenants and billing .
THE HVAC SYSTEM AND INSTALLATION Through numerous iterations of life cycle costing and consideration of the specific requirements for each building component , the HVAC Solutions were agreed upon .

The Hilton chiller plant – hydronic module chiller .
Residential Block The high-rise residential block is fitted out with a VRF 2-pipe system . The condenser kits are located in a well-ventilated common plantroom on every alternate level on the building .
Ducted hide-away units are centrally located within lowered ceilings in the passage of each apartment . Supply air is introduced into each occupied space via sidewall grilles due to limited ceiling void in these areas .
The VRF system has smart home adaptability should a tenant choose to control the HVAC remotely .
