High-Bay LEDs Improve Lighting Efficiency and Performance at the University of Illinois
May 18, 2015 - Lighting
The University of Illinois at Urbana-Champaign and LED technology go back a long way. University of Illinois alumnus Nick Holonyak Jr. invented the first practical visible-spectrum LED in 1962. Fifty years later, the Chancellor pledged for the campus to become the first major research university to commit to LEDs as its main source of lighting, with interior and exterior wayfinding fixtures to be replaced by 2025 and with the majority of all lighting to be LED by 2050.
During a project to upgrade the lighting at three gymnasiums in the Activities and Recreation Center, the university also wanted to increase illumination to meet the Illuminating Engineering Society’s recommended light levels, as well as save on energy and maintenance costs. The decision was made to replace the existing 400-watt metal halide fixtures with 100-watt Metalux HBLED high-bay LED luminaires.
The LED fixtures were chosen to reduce lighting maintenance labor and electrical consumption, since LEDs generate a fraction of the heat compared to other sources. University staff also wanted the ability to individually control the lighting on each court instead of having to switch on all the fixtures at once.
The Metalux HBLED luminaire features precision designed optics available in narrow and wide distributions, four lumen packages up to 30,000 lumens and three color temperatures. The product is designed to satisfy multiple mounting heights – even some low-bay applications.
Power transformers seldom go down, but when they do the effects on campus operations are immediate and devastating
Central Connecticut State University sought a continuous on-site power solution that reduced its carbon footprint and helped it achieve aggressive Climate Action Plan goals. An RFP process revealed a stationary fuel cell power plant would be a good option for the university.
Presence Saint Francis Hospital's parking garage has a steady flow of vehicle and pedestrian traffic, but has not always been well lit. A final solution was found with Cree luminaires.
The new $1.3 billion Levi’s Stadium in Santa Clara, California, home to the NFL’s San Francisco 49ers, is the first NFL stadium to receive LEED Gold certification, with green features everywhere from its 27,000 square-foot green roof to its farm-to-table concessions offerings. One particularly crucial green feature is its use of recycled water for the flushing and irrigation systems.
