2. Target Field: Minnesota Twins
The Minnesota Twins’ Target Field was the second U.S. ballpark ever to become LEED-certified, and it is the only ballpark with LEED certifications in both construction and operations. After becoming certified with LEED Silver as a new building when it opened in 2010, Target Field went onto obtain LEED Silver for Existing Buildings: Operations and Maintenance in December 2011. In fact, upgrades to equipment, lighting, and HVAC in 2011 reduced electricity use by more than 12%, despite a new video board and added radiant heating units.
Target Field prides itself on being America’s most multi-modal, transit-oriented ballpark. The ballpark is accessible via light rail, commuter rail, buses lines, bike trails, and pedestrian routes, and its website offers information on traffic so drivers can plan avoid it. The park features low-flow urinals, dual-flush toilets, and aerated faucets use 30% less potable water than conventional fixtures and save about 4 million gallons of water annually. Meanwhile, its rain recycle system allows the Twins staff to use rainwater to wash the seating area; per game, the system saves them 14,000 to 21,000 gallons of water; 86 gallons of gasoline; and 57 man-hours of labor.
The field is illuminated by high-efficiency lighting and an automated system that shuts down lights across the whole facility at certain times each day saves the ballpark nearly $6,000 a year, while office staff play their part by turning off lights and computers, and engaging in other energy-saving behaviors, to help save nearly 5% on office energy use.
