About This Item


Full Description

Walmart's new, 135,000 ft2 green prototype store in Burlington, ON, Canada, includes a geo-exchange heating and cooling system, which uses 15 km (9 miles) of pipe beneath the store's parking lot to draw heat from the earth in the winter and pump heat back into the earth in the summer.
