After 18 days in the sun, the Passive House structure retains 639 kg of ice compared with the BC code-built house which retained 407-kg.

Launched on July 27, Vancouver residents and visitors were invited to learn about the Passive House Standard—the energy-efficient building design standard that requires almost no energy for heating or cooling—through a public display/science experiment called the Icebox Challenge

Two structures were placed at Olympic Village Square—one built to B.C.’s current building code and one to the super-insulated to the Passive House Standard.
