the direct path to sustainability

Miller Park Stadium

Role: LEED Consultant and Project Administrator

Rating: LEED EB O+M Silver Certification

Miller Park Stadium is located at One Brewers Way in Milwaukee, WI, where the $400 million Miller Park site totals 265 acres including the ballpark, parking for 12,600 vehicles, roads, bridges, and ramps along with extensive landscaping. Sustainable Building Solutions served on the green team for Miller Park’s achieving LEED Silver certification for Existing Building Operations & Maintenance (EBOM).

The USGBC recognized the Brewers and its partners, led by facility manager Johnson Controls, Inc. (JCI) with the certification noting that Miller Park is one of the most complicated buildings ever certified in the LEED Existing Building rating system, due to the nature of the facility, the sheer volume of people, materials, vendors, the operable roof, and overall complexity of the building operations. Additionally, the retractable roof makes meeting energy and ventilation thresholds more challenging.

Johnson Controls, Inc. managed the LEED process at Miller Park, helping the Brewers identify projects in many different categories to help them become more sustainable, as well as help draft policies to adhere to sustainability goals moving forward. The LEED certification process involved coordination with many additional stakeholders at Miller Park including Performance Clean LLC, Grumman/Butkus Associates, Waste Management, ImPark, Hunzinger Construction, and Sustainable Building Solutions.

Steps taken to reach Silver certification include the following:

  • The Milwaukee Brewers and the Southeast Wisconsin Professional Baseball Park District implemented a Retro-commissioning project, which analyzed and made improvements to Heating, Ventilation & Air Conditioning (HVAC) systems, equipment and controls, plumbing systems and electrical lighting and power systems. This resulted in reducing 1,153 metric tons of CO2 emissions annually, the equivalent to taking 220 cars off the road each year.
  • A retrofit to water fixtures in Miller Park was completed, which will save three million gallons of water annually.
  • More than 40 large recycling containers were added in the parking lot areas, as well as 100 additional containers inside Miller Park.
  • All waste and recycling is now tracked, and 35 percent of all waste has been diverted from landfills to recycling since the start of the 2010 season.
  • On average, Miller Park recycles approximately 10 tons of waste from each game.
  • The new Hi-Def scoreboard uses 49 percent less energy than its predecessor.
  • Over 50 percent of all cleaning products meet sustainability criteria as “Green Cleaning” products.
  • All smoking areas are at least 25 feet from operable doors, windows, and intakes, which preserves the indoor air quality for occupants.
