As we’re gearing up for NAPHN18, the Ice Box Challenge is generating excitement through the country. A standard code box vs a passive house construction box, which do you think will win? Check out the Ice Boxes in NYC – and read about previous challenges in “It’s Time to Box”. Soon these very boxes may be traveling to a city near you!
About the Ice Box Challenge
The #IceBoxChallenge is a contest and an experiment to demonstrate how a home can be super energy efficient AND comfortable.
“In this corner”a structure built to the reigning champion…the Standard Building Code and the other a young and feisty upstart built to Passive House standards (a high-performance building standard that is a simple, quality-assured approach to designing and constructing better buildings). Both are filled with one ton of ice in order to test their performance during the summer heat. The Ice Boxes are left outside in the sun for 18 days. When they are opened, the amount of ice left in each box will be measured. How much ice is left shows how well each Ice Box keeps out the summer heat.
It’s a knock-out.
2017 VANCOUVER: PH VS. STANDARD BUILDING CODE
Two Ice Boxes filled with Just under a metric ton (1,000 kilograms) of ice for 18 days.
They were then opened and the ice melt in each box measured.
The Result: the remaining ice in the Passive House structure weighed 639 kilograms, compared to the 407 kg of ice in the BC code-compliant enclosure.
2017 SEATTLE: PH VS. STANDARD BUILDING CODE
Two Ice Boxes were each filled with 1,200 pounds of ice and left outside for 20 days. They were then opened and the ice melt in each box measured.
The Result: the ice left unmelted in the Passive House box was four times larger than that left in the code box.
This demonstrates the POWER of building as CLIMATE ACTION.
Pound for Pound…
PH is the greatest building standard of all time.
Passive House creates high performance buildings which conserve energy by reducing the amount needed to heat and cool spaces. Better building design through the Passive House standard can help us reduce our carbon pollution without changing our behaviour. These energy-efficient homes are comfortable, quiet and healthy.
The Ice Box Challenge has been used globally many times, including London, Brussels, Vancouver, and Seattle.
