Westpac’s new headquarters is impressive in so many ways including its exceptional functionality. The lighting management system is no exception with a huge DALI-controlled lighting system offering high levels of comfort, flexibility and energy efficiency.
Westpac Place is a 35-storey high-rise building, located in Sydney and is the headquarters of the Westpac Banking Corporation. With a floor plate of over 74,000 m2 it houses over 5,000 Westpac employees.
The firm responsible for the engineering of the base building and the tenancy fitout electrical services was the Webb Australia Group with Stowe Australia being the electrical contractor.
Complete Technology Integrations Australia (CTI), the Australian systems partner of TridonicAtco was chosen to supply and commission the advanced lighting control system.
The winDIM@net lighting management software from TridonicAtco is suitable for such jobs because of its simplicity and functionality.
A total of 286 DALI lines were installed. On each level the lighting is linked to a higher-ranking control system via a DALI/Ethernet gateway so that all the operation and monitoring functions for the lighting system can be handled centrally.
The CTI DALI system is also networked with the audio-visual system. DALI relays are used to control louvre blinds and video screens and to call up dimming illumination values or lighting scenes that have been pre-programmed for different tasks such as presentations or conferences.
The winDIM@net lighting management system enables the many benefits of DALI functionality to be used for central supervision (control, monitoring and evaluation). All the status information can be retrieved from the control gear, such as lamp failures, current dimming values and failure of hardware components. This greatly simplifies maintenance work.
The CTI DALI lighting management system offers more than just the convenience of lighting moods and impressive flexibility, it offers the basis for the energy-efficient operation of the lighting system.
To ensure that the prescribed illuminance values are achieved even as the lamps come to the end of their lives, the lamps are operated initially at a dimming value of around 75%. In line with the maintenance factors the dimming values are increased over time so that the offices are always lit at the same level. This intelligent adjustment of
illuminance values can save up to 18% of energy costs.
