More than 20 years old, the school's rooftop units were in dire need of replacement. Also, the school wanted to replace all of the controls in the facility with open technology LonWorks(r) controls, to better manage energy costs. The College of Technology's maintenance supervisor, Ray Carl, wanted to be able to control all the devices via the Internet, but he also had to meet stringent state budgetary guidelines.
A Control SolutionWhen administrators decided to automate the school's facilities control system, they selected the Vykon(tm) Building Automation Suite by Tridium Inc. to be an integral part of that upgrade. With a system that incorporated Vykon, the school now has the ability to access and control, from any standard Web browser, the LonWorks controls in the building, as well as the new hvac system on the roof, which uses BACnet(r).
"I am tickled pink," Carl says. "Because Vykon can integrate diverse control systems, we saved a lot of money." The school slashed its energy costs by more than 20% each month since the installation.
Systems integrator, Electro Controls, was awarded the Montana State building automation system (bas) contract. The company's general manager, Jonathan Fry, says that when his company was awarded the contract, college officials wanted to replace all of the building's control devices with devices that used the LonWorks communications protocol, allowing the maintenance staff to access and control those devices.
The maintenance staff also wanted to have access to the control devices at anytime and from anywhere via any standard Web browser, which is why Fry recommended that Tridium's Vykon be a part of the bas.
"The college never really considered the integration of the four rooftop Trane hvac units, which have BACnet controls with the controls in the rest of the building that used LonWorks communication protocol. They were considering that a separate issue," he says. "But with just one extra day of work, we were able to integrate both systems easily. Vykon made it so easy and so simple to connect these two systems."
