The #IceBoxChallenge is a contest. It’s also a public science demonstration that invites the public to discover the benefits of high-performance buildings.

Open Green Building Society was invited to play leading role in design and development of the project website and contest functionality.

The Ice Box Challenge comprises two small structures. One is built to the BC Building Code, and the other is built to the super-insulated Passive House Standard. Each Ice Box contains one tonne of ice. The Ice Boxes are left outside in the summer sun for 18 days. Then they are opened and the amount of ice left in each box is measured. How much ice is left indicates how well each Ice Box keeps out the summer heat.
