LED CASE STUDY: HOSPITAL LED Case Sudy – High Rise

See advantages of American Made LED Lights in a Hospital LED Case Study – 10 Year Warranty and Lowest Total Cost of Ownership LED Lighting.

Project: Thomas Jefferson University – Edison Building North Tower

Highlights: 24 Story Stair Tower LED Retrofit with Delamping

Address: 130 S. 9th Street, Philadelphia, PA 19107

Owner: Thomas Jefferson University (www.jefferson.edu)

LED Installation: Q2 2014

Opportunity for LED Lights: Lighting consumes a significant amount of electricity for a multi-story building. Like similar structures, the North Stair Tower at the Thomas Jefferson University Edison Building had inefficient T8 fluorescent fixtures lighting the stairwells. With a 24/7 run time, totaling 8,760h/year, the existing fixtures used 52,560 kWh per year. The $.08/kWh electricity rate resulted in a lighting cost of $4,204 per year, and a annual replacement maintenance cost of $1,600.

LED Lighting Solution: Independence LED provided a delamping strategy to replace the existing 100 fixtures, each using 60w of energy (after ballast factor), with 50 fixtures using 32w each, resulting in a savings of 74%. The external driver and aircraft grade deep fin aluminum heat sinks on the LED tubes provide the robust thermal management to provide a 7-year lifetime at the 24/7 run time, versus the 2.3 lifetime of the existing fluorescents. The new LED’s also created a brighter, cleaner light as shown in the photos below.

Hospital LED Case Study Results: By reducing the fixture wattage from 60w to 32w, and cutting the number of fixtures in half from 100 to 50, the total annual savings is 38,544 kWh and $3,084 per year. Over the 60,000 hour 7 year life of the LEDs at 24h/day the lifetime energy savings is $21,584. The

project also earned a $3,854 rebate from the local energy provider. Thomas Jefferson plans to retrofit the South Stair Tower with our LED products based on the success of this project.
