When financial savings are critical to every institution, facility managers demand even more from their energy systems while looking to spend less. One way to achieve significant energy savings and healthy schools without making a substantial capital investment is through energy monitoring and chiller plant optimization. The greatest energy savings available to school and university campuses can be generated from a facility's existing chiller plant operation, where even small tweaks can result in significant improvements. Web-based monitoring systems can be an effective tool for analyzing large chiller plants and district cooling systems. Built on open standards, they offer networked solutions that collect and format data in real time and defined timeframe increments; monitor operations and equipment errors; and deliver oversight via Web-based alerts and alarms. Based on the information generated, engineers are able to track performance and remedy any malfunction in order to optimize energy efficiencies.
