News release: The University of Texas of Arlington will save about $1.1 million in energy and maintenance costs after completing $9.9 million in facility upgrades. The improvements will reduce the institution's energy usage by 9.8 million kilowatt hours a year. Fifty-five UT Arlington buildings received upgrades. Improvements included the replacement of two thermal energy plant chillers, upgrades to heating and air-conditioning systems and roofing repairs and improvements. The project was funded through a low-interest loan from the 2009 federal stimulus package and will be repaid with the energy savings.
