Commercial LED Lighting Solutions Case Study Series – Parking Structure – Colonial Parking

Posted on Thursday 17th December 2015
The following case study is an example of the growing application of energy saving LED lights for commercial LED lighting solutions cross a broad range of applications. If you would like to submit a case study, please contact us via Project: Ships Tavern LOMA Parking Garage Highlights: One of the first Parking Structure LED Retrofits Address: 201 S King Street, Wilmington, DE 19801 Owner: Colonial Parking ( Opportunity for LED Lights Lighting consumes a significant amount of electricity for a seven-story parking garage. The Ships Tavern LOMA Garage in Delaware had inefficient lighting fixtures with 175w metal halide bulbs in each. At 24 hours of operation per day totaling 8,760h/year, the fixtures each use 1,533.6 kWh per year. At an electricity rate of $.12/kWh the lighting cost was $184 per fixture per year. LED Lighting Solution Independence LED provided a 58 watt LED vaportight solution that saves 117 watts per fixture, resulting in a savings of over 79%. In addition to reducing energy costs, the new vaportight fixtures produce a brighter and safer environment for motorists. The external driver and aircraft grade deep fin aluminum heat sinks on the LED tubes within the fixtures provide the 60,000 hour longevity to withstand the demanding 24/7 run time and also reduce the maintenance costs associated with metal halide bulbs. LED Case Study Results By reducing the fixture wattage from 175 to 58, the annual savings is 1,218 kWh and $146 per fixture. Over the 60,000 hour 7 year life of the LEDs at 24h/day the lifetime energy savings is $1,093. With historical 3% annual increases in energy cost and reduced bulb replacement and maintenance labor, the savings is over $1,231 per fixture. The LED retrofit project’s energy reduction earned a significant rebate through Energize Delaware, and initiative of Delaware’s Sustainable Energy Utility (SEU).
