Nearly 100,000 kWh Per Year Will Be Saved by Burlington, Vermont Grocery Store.

Boston, Mass., May 24, 2011Digital Lumens, developer of the industry’s first Intelligent Lighting System™, and Leading Edge Design Group, a leading national provider of energy optimization services, announced today the completion of an energy efficient lighting upgrade for the retail areas of City Market/Onion River Co-op.  Burlington Electric provided the project incentive.

The deployment of Digital Lumens’ Intelligent Lighting System will drastically reduce lighting operating and maintenance costs, and deliver savings of nearly 100,000 kWh of energy per year – equal to more than 64 tons of carbon.  City Market installed the Digital Lumens Intelligent Light Engines (LED-based fixtures with embedded controls) into the shopping areas and uses LightRules (central lighting and energy management software) to configure light levels and monitor energy usage.

“The Digital Lumens Intelligent Lighting System installed by Leading Edge Design Group is delivering dramatic cost savings and decreasing our energy usage, while also giving us accurate data on lighting energy consumption store,” said Brent Demers, Facilities Manager, City Market. “With LightRules we have accurate information on just how much energy we’re using, which helps us manage our overall consumption.  In addition, numerous customers have complimented us on quality of light, meaning that we’re saving energy and making our customers happy.  That’s a successful project.”

“We are proud of our work with Digital Lumens on the City Market deployment,” said Gary Hubbard, Energy Efficiency Program Manager at Leading Edge Design Group. “The combination of our energy optimization services and Digital Lumens’s innovative LED-based Intelligent Lighting System has helped City Market achieve its sustainability goals while decreasing costs and enhancing the customer experience. We look forward to future collaboration to bring these same benefits to other customers, as well.”

“This deployment brings the benefits of our Intelligent Lighting System to retail environments, and we are delighted that efficiency-driven City Market team has chosen Digital Lumens,” said Mike Feinstein, Vice President of Sales and Marketing for Digital Lumens. “The combination of lighting quality as well as cost savings driven by improved operational efficiency makes our System a great solution for a variety of environments.”

Additional benefits of the City Market lighting upgrade include:

  • Improved product presentation (the Digital Lumens solution produces brighter cleaner light)
  • Increased produce and meat shelf life (LEDs do not produce damaging UV rays or excess heat)
  • Reduced burden on the air conditioning system (because the Digital Lumens solution generates much less heat than the legacy lights), and
  • Reduction in maintenance cost and downtime (Digital Lumens solution requires maintenance five to ten times less often).
