Case Study
Regional Hospital
A large private, not-for-profit hospital engaged Clear Energy as a subcontractor to an ESCO to audit and develop a scope of work to retrofit or replace existing lighting. The project included three million square feet of buildings and exterior lighting across its campuses in three Arkansas cities. The project goals were to lower energy usage and reduce energy costs, improve the overall aesthetics of aging facilities, and lower maintenance expenses.
Our Work:
Lighting audits were conducted at the three hospital campuses. We developed a design that would meet the goals for the hospital and provide the energy savings to help our ESCO partner deliver a robust performance contract. The scope of work included retrofitting ~21,000 fixtures from fluorescent, incandescent, and high intensity discharge (HID) lamps to more energy efficient LED lamps or fixtures. It also included replacing older troffers and can lights in public areas of the hospitals with updated architectural or flat panel fixtures. The project schedule was coordinated with the hospital staff at the three campuses to allow normal business operations to continue with minimal interruption during the lighting retrofit.
All hazardous materials removed during the lighting retrofit were recycled.
The Results:
The project reduced lighting energy demand by ~850 kW and ~4,100 MWh annually. The light levels were equal or greater after the lighting retrofit, while light color uniformity and standardization was provided through the retrofit. In addition, removing and replacing older style fixtures with more modern fixtures provided a remodeled and updated feel in the public areas.
