About the Pratt Brooklyn Ice Box Challenge

What is the Ice Box Challenge?

The Ice Box Challenge is a fun and interactive public installation and contest that demonstrates the advantages of Passive House. Two boxes are filled with an equal amount of ice and displayed for public viewing on Pratt Campus for a one-week period. One box will be constructed to local building regulations, while the other will meet the international Passive House Standard, a highly energy efficient building performance standard. Each box is filled with an equal amount of ice at the beginning of the experiment and at the end of the week the amount of ice left in each box will be measured, with the level of ice remaining used to demonstrate how well each ice box passively kept out the heat.

Better building design can help us reduce our carbon pollution without changing our behaviour. Buildings that prioritise efficiency first are comfortable and healthy.

This is the First-Ever US Collegiate designed-build Ice Box Structure. The boxes will form a public installation, on display from May 1-8, 2023, in Brooklyn, NY USA.


What’s on at the event?

Visitors can learn how Passive House offers high level of comfort, can help meet climate protection goals, and make significant energy savings. Please join us at Pratt Institute, and celebrate with everyone, including the creators of this historic project, Pratt students and their visiting Professor In Cho,  along with the PHFE team.  Check out high-performance building industry sponsors, attend the opening and closing ceremonies – and enter the contest with your best guess of how much ice will remain in each box at the week’s end. We hope to see you there!
