Chestnut Hill Star Market

The store is the first supermarket in the nation to use all LED lights for its interior and exterior lighting, reducing energy consumption by 50 to 65 percent when combined with other energy-saving elements. While the parking lot was originally specified with high intensity discharge (HID) fixtures, Cree LED luminaires were selected for their advanced technology. Cree Edge™ area luminaires are expected to be maintenance-free for at least ten years. In contrast, the store’s previously installed HID luminaires required relamping every eight to 18 months.

The LED lighting design required less electrical infrastructure (i.e. conduit, wire, circuit breakers, transformers, etc.), resulting in lower construction costs compared to the HID solution. Additionally, Cree's multiple optical distributions (over 20 are offered) allowed for better “on target” lighting performance, resulting in a reduction in the number of luminaires and poles needed, further lowering construction costs.

Residents in the neighboring community had concerns about the store’s exterior lighting meeting light trespass requirements. The Cree installation meets local lighting mandates for cutoff while providing improved lighting performance that enhances visibility and security.

“This is a win for everyone involved,” said Ken Mahtesian, senior project manager for Supervalu/Shaws Division. “The landlord is thrilled with the parking lot’s appearance, and since there is a common area maintenance fee, the other tenants and Star Market couldn’t be happier with the reduction in energy and maintenance costs.”

The Chestnut Hill store is a test location for Supervalu to study energy-efficient technologies that can be used at other locations across the country. Supervalu is committed to reducing energy use in all of their stores. This could mean huge savings for the company, which estimates its annual electric bill for the more than 200 Shaw’s and Star Market stores at nearly $35 million.
