“We don’t want our energy use to add greenhouse gases like carbon dioxide into the atmosphere. So we’re measuring our impact and reducing where we can, such as using high efficiency lighting,” commented Farrell.
Working with design/build firm Opus North Corporation, several options were considered for the company’s outdoor illumination, including simply installing more high pressure sodium (HPS) fixtures. However, one of the challenges with other lighting technology is that 30 percent of all U.S. outdoor lighting is wastefully directed skyward. Since LED fixtures use dozens of individual LEDs, light control is managed via individual optics on each LED, making it inherently easier to prevent light pollution. Considerable attention was also given to the issues of spill light control and glare.
Farrell championed the building’s green design and challenged Opus to find technologically advanced solutions to accommodate his commitment to the environment. With this in mind, the team turned to Cree, a leading manufacturer of high-quality, specification-grade LED luminaires. Rob Ezerins, Senior Design Architect with Opus North Corporation, began working with the Cree team to determine appropriate luminaires for the 51,000-square-foot parking lot.
