Upgrades to LED Lighting to Reduce Energy Costs and Improve Light Output for Students and FacultyDownload PDF
A leading Northeast university needed to reduce the excessive energy use and maintenance costs of the existing lighting system for the court area of their recreation facility. The area consists of two basketball courts used for various activities and a track hockey court and an upper-level perimeter track illuminated by typical high bay fixtures.
The high wattage metal halide high bay system did not allow for control strategies to manage long operating hours with inconsistent occupancy and daylight availability. Additionally, the high bay fixture design consisted of wasted up light, optics that illuminated obstructions rather than the target area, and was unable to dim during ample daylight contribution. The perimeter’s fluorescent system had the same deficiencies.
Metal halide systems have short lamp life and significant lamp lumen depreciation. Coupled with expensive and labor intensive lamp and ballast replacements resulted in maintenance challenges that included the use of a scissor lift to access the fixtures. Spot relamping resulted in a system that consisted of varied fixture intensity and color shifting which affected the spaces overall aesthetics and user experience. The fluorescent technology suffered the same outcome.
Leading Edge Design Group (LEDG) designed a turn-key Intelligent LED lighting solution to deliver what the university needed to improve energy efficiency and lower energy and maintenance costs. The intelligent lighting system included one LED fixture for every two metal halide fixtures and a one for one replacement of the perimeter fixtures. All fixtures are wirelessly connected and profiles commissioned via an easy-to-use software program that enables the implementation of energy saving strategies including occupancy planning, daylight harvesting, scheduling, and task tuning. The solution provides a higher quality of delivered light to the target area and improved light levels in the area.
The LEDG recommended solution provides university recreational facility the following immediate and long-term benefits:
- An 80% reduction in kWh and associated energy costs
- A 20% increase in light levels
- A higher quality of delivered light throughout the space
- An intelligent platform that allows for profile changes and a better understanding of the area’s use
- An intelligent platform that allows for future intelligent solutions to integrate into the overall university network
LEDG also coordinated the lighting system installation with university personnel to accommodate the facility’s heavy schedule and to make sure the court use was uninterrupted.
