How are the boxes constructed?

Each Ice Box sits tightly on its own platform. The Ice Boxes are built with timber studs and plywood. The Passive House Ice Box is over-insulated with Rockwool insulation and its window is triple-glazed, according to the Passive House Standard with Cascadia Windows.

Both structures are clad in treated oriented strand board, which is painted and waterproofed. The air sealing in the Passive House Box has been provided by SIGA’s Wigluv and Rissan products.

The Ice Boxes and platforms were built offsite, then delivered and pieced together onsite.

Who else has taken the #iceboxchallenge?

The boxes you see today were designed and built in Vancouver (BC) and presented as part of the Vancouver Ice Box Challenge in Summer 2017. Special thanks to Stark Architects and Footprint Sustainable Hosting for design and construction. The boxes are now on tour, visiting Seattle, New York City, Philadelphia, Washington (DC), Pittsburgh, and Chicago by the end of 2018.

During the New York City Ice Box Challenge (presented as part of the Brussels Days Celebration), the Brussels Capital-Region commissioned Belgian street artist Oli-B to paint the boxes, creating a colorful interpretation of two alternate futures for building practice.

Don’t miss the unveiling of the Challenge results at the Ice Reveal event: October 5th at 12:30pm.

Thanks again to our building product sponsors…

Feel free to investigate the Ice Boxes. Peer into the windows. Note the differences between the Ice Boxes and how Passive House design helps to keep the summer heat out and the cool air in.

Join us at Steel Plaza Sept 11 – Oct 5 to admire the boxes painted by Oliver Biname, who is a Brussels-based street artist. His colorful murals and sculptures have been featured all over the world!
