About the Ice Box Challenge Sydney

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 in Martin Place for a two-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 fortnight 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.

The boxes will form a public installation, on display from 21 February to 4 March, 2022, in Martin Place, Sydney.

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. You can also meet the APHA team and volunteers, check out sponsor booths, and attend opening and closing ceremonies – and enter the contest with your best guess of how much ice will remain in each box at the end of the fortnight. We hope to see you there!
