 Technical Services
As part of the overall refurbishment works, $5 million has been spent upgrading and enhancing the building services including the building control systems and the mechanical/fire/security equipment and plant.
These works included the installation of a new Building Controls System, which has been rolled out across the entire site. This system integrates the most modern functions and communicates with the security, lighting and fire systems.
With the integration process now fully functional, the property is considered to be a truly “intelligent” development.
Controls - Air Conditioning, Lighting and Security
The new Building Controls System is provided with high-level interface to the access/security system and direct control over the interior and exterior lighting.
After hour’s access and air conditioning operation is via a card reader system.
All aspects of the air conditioning and ventilation operation are continuously monitored at the Building Manager’s office with alarm functions to allow prompt attention to any breakdowns.
Temperature settings and operation times are all configurable via the Building Control System at the Building Manager’s office.
Security
Access Control System
Vehicle entry to the car park is controlled at all times by a security ‘Air Key’, which operates the boom gate controls for each car park building for both entry and exit.
After hours the site is secured by electrically operated gates at the Wetherill Street South entry. The ‘Air Key’ is programmed to also operate these gates.
The ‘Air Key’ credential devices are coded radio frequency transmitters, with two push buttons, attached to a key-ring. They have a unique identification such that each ‘Air Key’ will be programmed to operate only the designated gates, for the days and time periods programmed. The ‘Air Key’ also has a built in proximity credential device that operates as a normal proximity card when presented to a card reader at the doors and in the lifts.
Close Circuit Television
Close Circuit television provides surveillance of the internal roads and each site entry point and the ground floor entry lobbies of both commercial towers.
Lifts
Both commercial towers are serviced by eleven (11) person Otis/Schindler lifts operating from the basement to all upper floors. The main office tower has three (3) lifts while the smaller tower has one (1) lift.
Air Conditioning
Air conditioning is provided to each level by a combination of two (2) water-cooled package units. One unit serves the eastern side of the building and one serves the western side of the building.
Two independent condenser water circuits serve the east and west package units. Each of these condenser water systems is fitted with a pair of pumps with automatic duty standby changeover for maximum system reliability.
Each system is provided with a number of independently controlled zones, both on the building perimeter and in the centre zones. Variable air supply and electric duct heaters are used to control temperature.
Ventilation
Outside air ventilation is provided to each air conditioning plant room and is distributed via the air conditioning system.
Supplementary Condenser Water Loop
A supplementary condenser water loop is installed to allow tenants to install supplementary air conditioning systems, such as computer rooms and high-density meeting rooms.
This supplementary condenser water loop is provided with an independent cooling tower and a pair of automatic changeover duty/standby pumps to increase system reliability.
