Project: Chapel Square Garage at the Omni New Haven Hotel
Highlights: One of the first parking garage LED retrofits in CT
Address: 155 Temple Street, New Haven, CT 06510
Opportunity
Lighting consumes a significant amount of electricity for an underground parking garage. Like similar structures, the Chapel Square Garage at the Omni New Haven Hotel had inefficient T12 fluorescent fixtures, some at 98 watts each. With a 24/7 run time, or 8,760h/year, the existing fixtures used 212,298 kWh per year. At a $.128/kWh electricity rate , the T12 tubes cost $54,544 per year to operate. In addition to the high electricity costs, the existing fixtures produced a poor light quality, which was seen as a potential security issue.
Solution
Independence LED partner Green Garage Lighting provided a 50 watt commercial LED lighting solution, a vapor-tight fixture, that saves an average of 63% per fixture. Propark, the parking management company for the Chapel Square Garage, was also pleased that the commercial LED lighting produced more light with less energy, increasing levels in certain areas from 20 foot candles, to 75. “We are very pleased with the new lights in the Chapel Square Garage,” said Steve Foster, Propark senior account manager. “ The increased lighting levels create an even greater feeling of comfort and security for our guests.”
Results
By reducing the fixture wattage from an average of 63%, the total annual savings is 269,366 kWh and $34,344 per year. Over the 60,000 hour 7 year life of the LEDs at 24h/day the lifetime energy savings is $410,870. With historical 3% annual increases in energy cost and reduced bulb replacement and maintenance labor, the lifetime savings is over $467,900. The project earned a $76,000 rebate from the Connecticut Energy Efficiency Fund, and is a Green Parking Council Demonstrator Site.
