Twelve racquetball and three squash courts at the Activities and Recreation Center (ARC) were retrofit with 193 fluorescent and 96 mercury vapor light fixtures. The project was funded by the Student Sustainability Committee through an interest-free loan of $75,000.

Once the lighting retrofits were completed, occupancy sensors were installed in all 15 courts.

The overall cost of the project ended up at $61,203.69 -- $13,796.31 less than the original quote. Campus Recreation requested that the remaining balance stay with the division and be used to further fund energy reduction projects within their facilities.

The total average reduction in power consumption is 129,226 kWh. This is a 75.7 percent decrease in consumption, which translates to an annual savings of $9,020. The simple payback for this project is 6.78 years.

The eighth annual Boneyard Creek Community Day will be held on Saturday, April 6 from 9 a.m. to noon.
