Many modern architects are more concerned with environmentally friendly building practices than they are with creating aesthetically pleasing forms, and the Ice Box Challenge is a testament to the potential that eco-architecture could have all over the world. The challenge is simple: during the peak of summer, one ton of ice will be placed in two houses -- one designed according to local building codes and one to the "passive house standard" -- and after 18 days, people will get to see which house did a better job of keeping in the cold and keeping out the heat.
The Ice Box Challenge is taking place in Brussels, Vancouver, Seattle, and New York City. Throughout the course of the challenge, both houses will be open to the public, allowing people to see firsthand the environmental benefit that passive houses have.
