Net-Zero Energy Retail Store Debuts in Illinois

December 11, 2013

Walgreens on November 21 opened a net-zero energy retail store in Evanston, Illinois that it anticipates will generate at least as much energy as it consumes over the course of a year. The facility is powered by two wind turbines, nearly 850 solar panels and a geothermal system tapping 550 feet into the ground. The company reports this is the first time it has combined all three renewable energy sources in a single store.

The company's engineering estimates indicate that the store will use 200,000 kilowatt-hours of electricity per year, and will generate 220,000 kilowatt-hours per year. The building also uses LED lighting and daylight harvesting, and was constructed with energy-efficient building materials. The company is seeking platinum certification for the store through the U.S. Green Building Council Leadership in Energy & Environmental Design (LEED) program and Net Zero Certification through the Living Building Challenge, and has received GreenChill platinum certification through the U.S. Environmental Protection Agency.
