CASE STUDY:

Agnew Associates converted University Medical Center’s chilled water system into a primary/secondary pumping system to reduce overall pumping energy at the hospital. The retrofit design also sought to address the low temperature difference seen at the central heating and cooling plant operated by Texas Tech University. The result was a reduction in electrical costs for the hospital and a 14° temperature difference in the chilled water system. This temperature increase resulted in substantial energy savings for the central plant, which translated into reduced operating costs. It was a win-win for the hospital and the Texas Tech central plant.

According to Agnew Associates President Dwayne Agnew, "This project proved to us that the primary/secondary pumping system can play an integral role in reducing costs. University Medical Center made it very easy for us to track results because they had been taking measurements throughout the project to determine the amount of energy being used."
