CSUSB facilities services receives national award for energy efficiency

     

Cal State San Bernardino’s facilities services department has designed and implemented an automatic control system that efficiently chills water and disperses it to the university’s air conditioning systems to cool the campus, saving about $340,000 annually in energy costs.

The high efficiency variable speed drive secondary pumps send chilled water from the central plan to campus-wide supply loop.

For its efforts on the automatic system, which is known as the as the “Most-Open Valve Heating and Cooling Strategy,” the department will receive the Effective and Innovative Award from the APPA, an association of more than 7,000 educational facilities professionals in the United States, Canada and abroad. The award will be presented during the APPA 2014 conference in San Diego on July 24.

“Using this method to chill water, the cooling system reaches and maintains equilibrium more readily,” said Tony Simpson, senior director of facilities services.  “Therefore, controls are not overreacting, and temperature swings and drafts from compensating air handlers have been eliminated. And that maintains customer comfort levels throughout large daily and seasonal temperature fluctuations.”

With the automatic controls, equipment is not overdriven, which extends the lifecycles of the equipment, and maintenance and repair activities are less frequent, translating to reduced labor and capital costs, Simpson said.

And because chilled water production is now done during off-peak business hours, maintenance and repairs can be done during regular working hours, saving premium labor costs, Simpson said.

The award marks the fourth time the CSUSB facilities services department has received a national award. The department received the APPA 2006 Effective and Innovative Practices Award, the APPA Award for Excellence in Facilities Management in 2007 and the Energy Project of the Year National Award in 2009 from the Association of Energy Engineers.
