Located in Southern in Chester County, PA, this University specializes in liberal arts, education, and science curriculums with over 11,000 undergraduate and graduate students. The university manages a portfolio of over 60 buildings across 30 acres. In 2006, the university embarked on an ambitious utility conservation project involving a combination of water conservation, lighting retrofits and controls, solar film, and electrical and HVAC upgrades. The centerpiece of this project was to be a 6,000+ point campus-wide building automation system that would provide single-seat monitoring and control of the campus systems, seamless third party, and complex demand limiting strategies designed to reduce the peak demand during the summer ratchet period. In October, 2007, Radius Systems was chosen over 3 other much larger vendors based on overall responsiveness and customer service, reputation of the Automated Logic product, performance in providing controls for two buildings on campus prior to the RFP, and demonstrated knowledge of HVAC, energy management, systems integration, and building automation systems.
The new campus system provided by Radius includes a WebCtrl based user interface, DDC controls for 53 buildings on campus, as well as integration to several legacy systems and third party devices. Priority trend data is stored for 2 years.
Utilizing a modbus interface the two primary campus meters, the Automated Logic monitors instantaneous kW and performs active demand management during the summer ratchet months. This system was implemented in August 2008 just prior to the fall semester (which is historically when the University sets its summer peak). The results – a 20% reduction in electric, natural gas, and coal energy costs.
