University of Utah
Serving more than 31,000 students, the University of Utah is the state’s premier institution for higher learning. Its facilities comprise 298 buildings across more than 1,500 acres. The university has adopted long-range plans to make the campus even more environmentally friendly and to become carbon neutral by 2050. Starting in the late 1990s, the university has improved campus facilities by focusing on energy use and demand on site. They sought a reliable energy expert team who would not only address known needs but help plan for ongoing growth of the student population and opportunities for expansion over time.
Starting in 1998, the University entered into a partnership with OpTerra Energy Services to determine if enough savings could be generated to help fund all or part of a new central plant. What started out as a 13-building project scope eventually turned into an extensive project during which upgrades and improvements were implemented in 81 buildings, all under self-funding performance contracts. After completing five phases of energy efficiency work, OpTerra designed and installed a natural gas–fired turbine-generator and heat recovery cogeneration system and new substation switchgear to save energy and improve operations.
From the first energy savings performance contract in 1998 through the North Campus chilled water plant project completed in 2011, OpTerra and the university staff have worked together to make significant and lasting improvements to the campus facilities at the University of Utah. To date, the projects have saved the university over $27 million in energy costs, $5.9 million more than originally projected. By modernizing campus infrastructure, lowering utility and operating costs, and improving the overall reliability of campus facilities, the OpTerra energy program has successfully met the university’s goals to modernize and become more self-sustainable.
