The #IceBoxChallenge is a public science experiment that uncovers the benefits of Passive House design and construction.

About the Ice Box Challenge

The #IceBoxChallenge is an experiment to demonstrate how a building can be super energy efficient AND comfortable. The Ice Boxes are left outside for 20 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 late summer heat. Better building design can help us reduce our carbon pollution without changing our behavior. Energy-efficient homes and buildings are comfortable, quiet and healthy.

Why Passive House Buildings?

Quite simply, it’s how we build & feel better.

Passive House buildings are reliable, affordable, comfortable buildings that use energy efficiently, so you’re heating or cooling only your building and not the outdoors. They stay comfortable and quiet throughout the year, including through summer heatwaves, winter storms and power outages. The buildings use up to 90% less energy for heating and cooling than other buildings do, while maintaining good indoor ventilation and air quality. They are easy to maintain. They are also affordable to build, own, live in and work in.

Passive House Northwest promotes highly energy efficient construction through implementation of the Passive House concept. Passive House (aka Passivhaus) is the world’s leading standard for energy efficient construction. It combines building enclosure efficiency and passive solar strategies in a system for designing and building cost effective, comfortable, energy efficient buildings.

About the Design

These boxes were given to Seattle by the City of Vancouver and Passive House Canada after the Ice Box Challenge there.

Vancouver’s buildings all try to capture the view. Like Seattle, Vancouver is surrounded by the Salish Sea and Pacific Coast Ranges. This design seeks to capture one such view, and present it in abstract form. The “Lions”or “Ch’ich’iyúy Elxwíkn”, which translates as “Twin Sisters” are unique to Vancouver and easily recognizable from much of Greater Vancouver. This easily recognisable Vancouver landmark, with its snow, that almost year-round tops these peaks, informed these Ice Boxes.

The Seattle Ice Box Challenge is made possible by the in-kind support and Ice Box donation of City of Vancouver and Passive House Canada. The Seattle Challenge is provided by Passive House Northwest, with presenting sponsorship and volunteer support from NK Architects, and sponsorship support from the local Passive House industry.
