For energy solutions provider Alliant Energy, demonstrating a commitment to sustainability and clean energy is an important part of their mission. And their high-profile solar carports stand testament to this mission in front of the company’s headquarters.
Much of the critical work on the carports were done mid-winter in Madison, WI—a city that is no stranger to heavy snows and frigid winter temperatures. Despite these unfavorable conditions, the installation was completed successfully and safely.
Inverted structures were used for the carports to direct rain and snow to a single gutter system. This design helps to avoid large amounts of snow shedding and prevent the possibility of falling snow and ice from injuring those below. A larger clearance height on the outer edge of the carport was chosen to reduce tall vehicle collisions and for aesthetics.
While these covered parking spaces are not the closest to the building’s entrances, they are the first spots to fill up each morning. Alliant Energy employees typically need to arrive an hour early to work to find a space under the protection of the solar canopies.
