It should come as no surprise that hospitals are among the largest consumers of energy in the country. Operating continuously throughout the year with a large fluctuation of employees, patients, and visitors passing between rooms full of energy intensive medical equipment means energy costs add up quickly. The greatest operating expense lies in the sophisticated heating, ventilation, and air conditioning systems that control the temperatures and air flow throughout the buildings and in the temperature sensitive operating rooms. According to a 2007 study, there were approximately 3,040 large hospital buildings in the U.S. averaging 644,300 sq. ft., and requiring regular HVAC maintenance and scheduled repair. Of these, 612 utilized chilled water over forced air for their cooling needs. The total kWh for these facilities was a staggering 13 billion, or approximately 21,757 thousand kWh per building. At an average electricity rate of 79₵/ kWh, the energy expenditures per building were enormous. With seven years of inflation and rising energy costs, those numbers have only continued to grow.

At tekWorx, our approach to chiller plant optimization allows chiller plants at critical facilities like hospitals to lower unnecessary energy consumption up to 50% by ensuring each piece of equipment is running at its most efficient point. This significantly reduces operating bills at such client projects as Bayfront Medical Center and Jackson Memorial Hospital (Florida). Using an adaptive control system, tekWorx continuously monitors critical system parameters in real time and automatically adapts online operations. The result; a lot less kWh, lower maintenance and training costs, and better control of overall operating costs.
