Macy’s Green Team Learns from Walgreens Net Zero Energy Store

POSTED UNDER Partnerships & Awards

Macy's, Inc. and its associates strive to incorporate sustainability into what we do every day. This includes how we operate and renovate our stores, offices and distribution centers – from using solar tube technology to capture sunlight and project it into distribution and fulfillment centers, to our use of LED lighting, to even our store fixtures selection. These sustainable changes are good for our buildings, our bottom line and most importantly, our employees and customers. While we‘ve made great strides toward our sustainability goals, there are always new ideas and technologies that we can explore.

Walgreens clearly feels the same way. Earlier this year, Walgreens invited Macy’s Green Team – a cross-functional group representing a variety of disciplines, including Energy Services, Mechanical Engineering, and SPACE (Store Planning, Architecture, Construction and Engineering) – to tour the Walgreens (and the nation’s) first net zero energy retail store in Chicago. Net zero energy (or NZE) means the building produces as much or more energy than it consumes.

“Currently, we have facilities that utilize wind turbines, solar installations and geothermal technologies. This is the first time we are bringing all three of these technologies and many more together in one place,” said Mark Wagner, Walgreens president of operations and community management.

The Walgreens net zero store is already a huge success; they’ve saved on energy bills, and employees and customers have noticed and are enjoying the difference. Some key features include:

  • LED lighting throughout the store that can be dimmed and offset by the amount of sunlight that the windows let in via daylight harvesting. Similarly, at night, the LEDs are dimmed slightly to provide a nice transition for customers coming in from the dark outside environment.
  • Solar panels cover the roof, including the drive-through awning, to produce enough energy to power 30 Illinois homes a year.
  • Tapping in to geothermal energy obtained by drilling 550 feet into the ground below the store, where temperatures are more constant and can be tapped to heat or cool the store in winter and summer.
  • Two wind turbines harvest energy from the famed winds of the Windy City.

Walgreens provides weekly tours of the store and is willing to share their ideas and insights with businesses and customers alike. While Macy’s utilizes many of these technologies, we’re now exploring the use of others. Successful collaboration like this creates a much greater impact, and helps us all become even better stewards of the environment.
