Net zero drug store

A drug store in the US is building what it says is the nation’s first zero energy retail store by using a combination of green initiatives.

The drug store, Walgreens, in Evanston, Illinois, will rely on a combination of several technologies to help it generate electricity and reduce its energy usage by 40 per cent.

Initiatives will include more than 800 rooftop solar panels, two wind turbines, and geothermal energy obtained by drilling 550 feet into the ground below the store.

Geothermal works by tapping into below ground level temperatures, which are more constant and thus could be tapped to heat or cool the store in winter and summer.

Energy-efficient building materials, LED lighting, daylight harvesting, and carbon dioxide refrigerant for heating, cooling and refrigeration equipment are also part of the plan.

According to engineering estimates, the store will use 200,000 kilowatt hours of electricity per year but generate 256,000 kilowatt hours per year, giving it a negative net usage.

Walgreens hopes to achieve LEED Platinum status with the store, which it will also enter into the International Living Future Institute’s Living Building Challenge.

A Facebook page has been set up for those interested in following the new store’s two-year journey to net zero status.
