An often-overlooked element of the design of any building is bird safety. As we’ve already discussed, Allianz Field was designed with an eye toward minimizing environmental impact, from careful consideration of the greenspace around it to the consumption of energy and water within it. Although Allianz Field’s private funding means it’s not subject to the state’s code about bird safety, the team was committed to abiding by it. Every year, hundreds of thousands of migratory birds pass through the Twin Cities, representing more than 300 species. And a lot goes into making sure any building this large is as safe as possible for our feathered friends.
