A seasonal solution

Recently opened in Edina, Minn., through a project coordinated by the Edina City Council, Braemar Field is one of the largest seasonal multi-sports domes in North America. The 100,000-square-foot inflatable dome measures 400 feet long by 250 feet wide by 75 feet high and was manufactured by Minneapolis-based Yeadon Fabric Domes using 28- and 32-ounce Shelter-Rite® fabric from Seaman Corp., Wooster, Ohio, and Tedlar® coating from DuPont Fluoropolymer Solutions, Wilmington, Del. The fabric was chosen for its durability, giving the structure a 20-year warranty, while keeping it looking clean and white.

The structure is supported by a fully automated furnace inflation system, including a wind sensor that adjusts the dome to a safe yet energy- efficient pressure level based on exterior wind conditions. A snow sensor also automatically sets the dome pressure and temperature to a level that will protect the structure in severe weather. The automation system allows the owner remote access via a smart phone or computer.

As an addition to the Braemar Sports Complex, which includes outdoor sports fields, ice rinks and golf courses, the dome solves an overcrowding issue faced by local youth and adult athletic teams, as its open interior is designed for multiple games of sports including soccer, lacrosse, baseball and fast pitch. The cover will stay inflated through April, and then be taken down to be stored during warmer months.
