Gustavus Adolphus, a private liberal arts college located in Minnesota about an hour south of the Twin Cities, was looking to upgrade its physical plant and related energy facilities. Then last spring, in the middle of the planning process, the college was severely damaged by a tornado. The unexpected disaster challenged the facilities staff to press on with their energy improvements despite widespread property damage. Since then, Gustavus has taken some important steps toward preparing itself for deregulation while simultaneously moving forward with its facility repairs and campus expansion programs.
Gustavus Adolphus wanted to be able to monitor and analyze the electricity and steam usage in each of its 28 major campus buildings. But there was only one central electricity meter and one central steam meter for the entire campus. The college needed to sub-meter each of the buildings and bring the data to one central location. The goal was to provide an efficient, centralized monitoring system that would allow the physical plant manager to:
Future goals included having information tools to shop the deregulated energy market for the best rates. Gustavus Adolphus needed a solution that would leverage the existing fiber-optic LAN communications infrastructure and would not require extensive new wiring. Specifically, the facilities staff needed a solution that would be effective in a multi-building environment where control points were widely dispersed. They also needed a guarantee of expandability to be able to accommodate additional buildings in the future. In the execution of its comprehensive upgrade plan, which now included a massive tornado-recovery reconstruction project, Gustavus Adolphus College entrusted cfar, an experienced energy management and system integrator firm based in Kennar, Louisiana, to find the best solution. To provide key technical viability for the project, cfar turned to Coactive Networks, the market leader in providing open solutions for connecting control systems to enterprise networks and the Internet.
Coactive Routers were installed at each of the 28 buildings, allowing the existing LonWorks control points to be integrated with the campus-wide local area network (LAN) and ultimately routed to a single host PC console. From this central location, Gustavus Adolphus staff can monitor, analyze, and evaluate real-time energy data and control functioning in all buildings. Coactives Router products, as part of Coactives IOConnect Architecture, provide a reliable, embedded, distributed solution to integrating next-generation networking technologies on both the control and data networking sides of the system. As to its role in this project, cfar design partner Mike Kasmarik says, Coactives connectivity technology provides an excellent means of moving energy management data over an existing Ethernet network. It negates the need to run another network. And it hugely expands the technical viability of an energy management system, making it possible to extend beyond a single building. In fact, it allows you to utilize the Internet, so distance is no longer a factor. Future uses of the Gustavus Adolphus system might include use-based billing of individual departments, accepting downloaded variable rate schedules, aggregating power purchases with affiliated colleges, accessing energy pricing/availability information, and even the ability to make on-line power purchases -- all via the Internet, from anywhere on the network.
The Coactive IOConnect Architecture addresses the convergence of control and enterprise networks with an open, embedded, distributed, and scalable solution based on a coherent approach towards the connectivity problem. The IOConnect Architecture supports open standards including LonWorks, the leading control network technology. It has been specifically designed to support and leverage Internet Protocol (IP) standards and technologies. This approach provides unmatched flexibility, reduces system costs, and enables new functionalities. The technical benefits offered by Coactives IOConnect Architecture include:
