LOUISVILLE, Ky. (AP) — A long-term effort to save energy on the University of Louisville's campus is surpassing its goals.
The university says fuel use on the main Belknap Campus has dropped nearly 50 percent. Electricity and water use dropped 27 percent and 31 percent from their annual usage before the project started.
The numbers are from 2011, the first full year after improvements were finished.
At the start of the project, engineers predicted fuel use on the campus would drop nearly 40 percent and electricity use by at least 20 percent.
UofL teamed with Siemens Industry in 2009 and launched the $21 million initiative. It included efficient lighting, updated heating and cooling and strategies to cut water consumption.
The university is paying for the improvements with savings from lower energy costs.
