PROJECT BACKGROUND
Nestled in the historic warehouse district of downtown Minneapolis, Target Field is the most
urban ballpark in the country. Home to the Minnesota Twins, the Major League Baseball team
for the Minneapolis/St. Paul metropolitan area and greater “Twins Territory”, the new ballpark
achieved LEED Silver Certification and is the greenest MLB ballpark based on certification
points achieved.
GREEN CATALYST
Placed on a previously contaminated industrial site on the edge of downtown
Minneapolis, the new ballpark connects the historic warehouse neighborhood with
downtown Minneapolis by literally bridging over rail lines and highways that separate
the two districts. The project’s location provides close proximity to the City Center
Shopping area, condominiums and a multitude of local businesses, including the First
Avenue Entertainment district, providing yet another draw to the downtown area.
STRATEGIES AND RESULTS
Target Field has created a new transportation hub in downtown Minneapolis, linking
Metro Transit’s newly extended Hiawatha light rail line and the Northstar commuter
rail service. The nearby Metro Bus station and bike trail also provide alternative
transportation access to the ballpark.
The project includes a custom designed rainwater recycling system to capture,
conserve and reuse rainwater. Water cisterns buried under the playing field will
capture water, which will then be filtered through an intricate mechanical filtration
system; this purified water will then be used for field irrigation and seating bowl wash-
down. It is estimated this system will save more than 1.26 million gallons of water per
year.
Additional water saving fixtures, such as low flow urinals, dual flush toilets and
aerated faucets in Target Field will use 30 percent less potable (drinking) water than
conventional fixtures. This will save more than 4.2 million gallons of potable water
per year, reducing the ballpark’s operating costs and demand on the municipal water
supply and treatment facility.
Energy efficient sports lighting fixtures and purchased Green-e accredited Tradable
Renewable Certificates (RECs) that equal to 70% of the predicted annual electrical
consumption over a 2-year period are a sampling of the ways this ballpark cut energy
costs as compared to other sports venues.
The selection of the ballpark’s building material, furniture and components is focused
on the use of recycled content, regional availability, and compatibility with LEED
indoor air quality standards. By cost value, 27.5% of the total building materials
content has been manufactured using recycled materials and 28.7% of the total
building materials value is comprised of building materials and/or products that have
been extracted, harvested or recovered, as well as manufactured within 500 miles
of the project site. Similarly, the construction waste generated onsite, 22,433 tons
(67.59%) has diverted from the landfill.
From an operational standpoint, the Minnesota Twins have committed to continuing
the goals of sustainability by providing a smoke-free facility as well as the
development and implementation of a green housekeeping program.
ABOUT THE MINNESOTA BALLPARK AUTHORITY
The Minnesota Ballpark Authority (MBA) is a public body that was created by the
2006 Minnesota State Legislature to oversee the construction and operation of Target
Field. MBA, who owns the site and the facility on behalf of the public, is committed to
protecting the public’s investment, while creating a new urban landmark that ties into
new rail lines and potential new development.
“Gaining LEED certification has been a
longstanding goal…It is our sincere hope that
the sustainability aspects of Target Field will
provide inspiration to other local, regional and
national projects of this magnitude.”
Jim Pohlad, Twins Owner and CEO.
