University of Arkansas, Fayetteville, Arkansas

The University of Arkansas at Fayetteville is a land-grant research university that serves more than 19,000 students from all around the world. Founded in 1871, the flagship of the University of Arkansas System operates more than 130 buildings on its 345-acre campus.

University of Arkansas Case Study, photograph of Old MainClear Energy has managed two significant projects for the UA, starting in 2007 when we completed lighting retrofits in the 30-year-old Walton College of Business building and the 70-year-old Ozark Hall. At the time, both buildings had a mix of T-12 and T-8 fluorescent lighting systems. The scope of work was:

  • Retrofit all three- and four-lamp T-8 and T-12 systems to two-lamp T-8 systems.
  • Retrofit two-lamp U-tube systems with two-lamp straight T-8 systems.
  • Retrofit all incandescent lamps to compact fluorescent lamps.
  • Install occupancy sensors where the reduction in operating hours economically justified the investment.
  • Replace all aging fixtures in Ozark Hall.

The retrofit and sensor work took place throughout both buildings, including classrooms, auditoriums, computer laboratories, offices, restrooms, and stairwells.

The work resulted in a simple payback of approximately four years, while improving both the quality and level of light. The project reduced the use of energy for lighting in the buildings by 65 percent and provided the impetus for an energy savings performance project covering all educational and general buildings on campus.

Clear Energy designed the lighting retrofits for the 60 educational and general buildings included in the energy savings performance project. We also performed the retrofit installation work for buildings in three of the six maintenance zones on campus. The buildings we completed included Old Main, the oldest building on campus (completed in 1875 and listed on the National Register of Historic Places), and other buildings in the historic core of the campus.

Other lighting projects completed by Clear Energy for the University include:

  • Replacement of inefficient high-pressure sodium lamps used along exterior pedestrian walks with a compact fluorescent system designed by Clear Energy. The new units generated a 63 percent reduction in energy costs and even greater maintenance savings.
  • Design of a compact fluorescent optical system for the new campus standard exterior post lighting. The system has been used in luminaires on the grounds of the newest dormitory, the new chancellor’s residence, and the Old Main lawn.
  • Specification, design, and installation of LED lighting for parking lots and for exterior architectural lighting of Old Main.

Campus energy efficiency projects are a component of the Climate Action Plan the University submitted to the American College & University Presidents Climate Commitment. More information about the University’s sustainability initiatives is available at
