Cromwell Track and Field Thermal Energy Storage System

Map Tour

 

40 feet below Cromwell Field rests a 3.2 million gallon thermal energy storage system made of 2,310 cubic yards of pre-stressed concrete.  This massive tank has minimal maintenance costs, and circulates chilled water throughout the buildings on campus to cool them and reduce air conditioning costs.  When electricity rates are lower at night, the water is stored in the tank and chilled.  During the day, while electricity costs are at their peak, this chilled water is then circulated throughout campus and electricity consumption decreases. 

 

A pump house beneath Grace Ford Salvatori Hall services the thermal energy storage system and regulates the flows of the system throughout campus.  The storage tank saves the university an estimated 4,500 megawatt-hours of electricity a year, which equates to about $400,000 of electricity costs saved.  Saving electricity reduces CO2 emissions, and the amount of electricity saved by this storage tank equates to the quantity of emissions produced by approximately 615 cars annually. 

 

Cromwell Field is covered with synthetic turf that provides numerous sports teams, individual athletes, and the Trojan Marching Band with a place to practice.  The field saves energy and resources by eliminating the need for watering, mowing, and replanting.
