Delta scores big in
ABS makeover
Headquarters of the Australian Bureau of Statistics (ABS)
DELTA BUILDING AUTOMATION AUSTRALIA HAD A BIG JOB RENOVATING THE HEADQUARTERS FOR THE AUSTRALIAN BUREAU OF STATISTICS (ABS) AT 45 BENJAMIN WAY, CANBERRA.
Optigo also provided network segregation through VLANs, since multiple services are con- nected to the same switches. The Optigo Con- nect solution has made integration at the field level simple and user friendly. Now, all network- ing tasks can be done quickly and easily by the controls technician, while IT still provides sup- port for firewall and server setup.
“THE AIR HANDLING UNITS ALL RUN MUCH QUIETER, AND THE CHILLERS DO NOT HAVE TO WORK NEARLY AS HARD EVEN DURING HEATWAVES.”
The building owner will have to wait to con- firm the new NABERS rating, but signs of energy improvement are solid. The air handling units all run much quieter, and the chillers do not have to work nearly as hard even during heatwaves.
The building’s network security has also been drastically improved with Optigo Connect, as all ports can be locked with the touch of a button using OneClick Secure. The Optigo Connect so- lution has empowered the OT team at 45 Benja- min Way to run an efficient, secure, and future -proofed building.
THE BUILDING OWNER wanted to improve the building’s energy use and increase its National Australian Built Environment Rating System (NA- BERS) score to more than 4.5 stars, out of a possible total of six.
Securing the network both internally and ex- ternally was a big priority as well.
Any refurbishment job comes with its own unique challenges, and this project was no different. All commissioning information and original source code of the previous BMS system had been lost due to a lack of redundancy, making it harder
to tune and achieve a higher NABERS rating. There was no existing network infrastructure, and no management system to measure the en-
ergy performance of the building.
Additionally, the system was connected di-
rectly to the conventional ADSL modem and a series of unmanaged switches, increasing the risk of unauthorized access.
Delta Building Automation teamed up with Optigo Networks to create an entirely new Op- erational Technology (OT) network backbone. The Optigo Connect solution provided a high- performance system that brought IT to the building operator level.
Optigo’s robust network connected more than 700 Power over Ethernet (PoE) and Ethernet de- vices across multiple services, including lighting, HVAC, surveillance, and electrical meters. Using a PoE-backed design helped improve energy effi- ciency in a cost efficient manner.
A self-healing ring topology with redundan- cy reduced the risk of losing data or suffering a network shutdown. To increase security, they replaced their unmanaged switches with Optigo’s managed switches, featuring One- Click Secure.
They locked all the ports on their switches in an instant, with additional VPN access to site.
