The situation.In the end of February 2013, Aerostar Airport Holdings, LLC took over operations and management of the San Juan Luis Muñoz Marín International Airport (LMM Airport) on behalf of the Puerto Rico Ports Authority. Aerostar developed a new vision to transform the LMM Airport into a world-class international destination, and formed a plan to create and maintain the facilities and infrastructure to maximize service quality and security.
“We want to greatly enhance the passenger experience at the San Juan Luis Muñoz Marín International Airport by significantly upgrading the terminal facilities and building a lasting and iconic airport,” said Randall Corsi, special projects, Aerostar Airport Holdings, LLC. “The parking facility was identified as an area of opportunity for not only increased customer satisfaction, but also energy savings.”
Available 24 hours a day, the parking facility provides short and long-term parking options, with approximately 2,000 spaces available. The parking facility was using 100-watt high pressure sodium (HPS) luminaires throughout the garage, which were causing issues. The older HPS fixtures used a significant amount of energy compared to LED replacement options, resulting in high electricity bills. HPS lamps have an extremely low color rendering index (CRI) of only 22, emitting a less than pleasant yellow light, and their typical 20,000 hour life makes for a higher failure rate than LEDs, increasing maintenance costs.
The solution.Aerostar chose the OSRAM PermaLED™ Low Profile LED Canopy Luminaire because of its high efficacy and integrated controls. Each of the existing 100-watt HPS fixtures were replaced with a 40 or 55-watt LED luminaires, not only helping the airport save money and energy but also providing bright white light that improved lighting uniformity. Unlike the yellow light from the HPS lamps, the vastly improved color rendering index of the LED luminaires can facilitate quick vehicle identification and increase pedestrian visibility, enhancing safety and feelings of comfort in the garage facilities. With the integrated controls, the facility can program each lighting fixture independently, therefore only emitting light when needed and resulting in enhanced (or significantly enhanced) energy savings.
The product.PermaLED Low Profile LED Canopy Luminaires are energy-saving LED alternatives to traditional HID luminaires up to 175-watts, leading to energy reductions of up to 74 percent. The nominal 3.1" height of these extremely durable luminaires is less obtrusive, making them ideal for canopy entryways, parking garages and stairwells. The LED system has a life rating of 100,000 hours (L86) and luminaire efficacy up to 113 lumens per watt. The PermaLED Low Profile Canopy Luminaire with integrated controls is IP66-rated and meets IEEE 62.41-2002 category C transient line protection requirements. The luminaires provide up to 10kV surge protection for effective suppression of most transient AC line surges, are ETL listed in the United States and Canada and DesignLights Consortium (DLC) qualified to meet most utility incentive program requirements, and are backed by a 5-year system warranty.
The bottom line.As a result of upgrading the lighting at the San Juan Luis Muñoz Marín International Airport parking facility to PermaLED Low Profile LED Canopy Luminaires from OSRAM SYLVANIA, Aerostar Airport Holdings, LLC anticipates an annual saving of 1,477,952 kWh, translating into $421,216 in energy savings and avoidance of 1,806,486 pounds of CO2 emissions from electricity plants. In addition, because of the long-life of the luminaires, the airport also expects to save approximately $29,800 in maintenance costs annually for ten years.
