The home of the Milwaukee Brewers from the year 2001, the Miller Park baseball stadium, has acquired the Leadership in Energy and Environmental Design (LEED) certification in the Existing Building Operations and Certification category.
It has received the recognition of being the first stadium having a retractable roof and the third major baseball stadium to acquire this certification. The facility manager for the stadium is Johnson Controls and it also monitored the LEED process. Johnson Controls succeeded in meeting the ventilation and special energy needs of the retractable roof present in the stadium.
The other two stadiums that acquired LEED certification include Target Field at Minneapolis and AT&T Park at San Francisco, both of which are open-air stadiums.
The upgradations that helped acquiring LEED certification for the stadium includes a high definition scoreboard that saves 49% energy, improvements in power systems, electrical lighting, plumbing, equipment and controls and HVAC systems, which is anticipated to minimize CO2 emissions equivalent to 1153 t per year.
Furthermore, the older water fixtures were replaced which may save up to 5.2 million gal of water consumption per year and over 140 new recycling containers were added, making it possible to recycle at an average 10 t of waste after every game. Over 50% of “green cleaning" products were used, which fulfilled the sustainability norms for certification. For preserving the indoor air quality, the smoking area was allotted 25 ft away from ventilation systems, doors and windows. Moreover, 7,000 lbs of food was donated to shelters and food banks during last year’s game season that offered 5300 meals.
