Ice Box Challenge at the 2024 Minnesota State Fair


Passive House is coming to the 2024 Minnesota State Fair! With the generous support of our sponsor Xcel Energy, the Ice Box Challenge will be set up at their booth outside of the EcoExperience.

Two boxes—one built to the local building code, another to the Passive House standard—are setup for the duration of the State Fair and filled with 2,000 pounds of ice, each. Monitoring devices and cameras inside the boxes can measure the temperatures and photograph the depleting ice. The amount of remaining ice left in each box at the end of the display period is then measured, and demonstrates how well each ice box kept out the heat and preserved the ice inside as a representation of the power of Passive House.

The Minnesota Renewable Energy Society is helping PHMN support this event from August 22 – September 2 at the Minnesota State Fair. Volunteers welcome!

Please contact us if you wish to support us at the MN State Fair, support the Passive House Network, or have other questions about the Ice Box Challenge.
