The Richmond Olympic Oval is to Vancouver as the Bird's Nest was to Beijing (though on a scale more befitting of Vancouver than Beijing). The 8,000-seat, 512,000-square-foot building uses a novel styrofoam insulation beneath the ice to obtain the necessary ice temp, thickness, flatness and hardness for a variety of events. Heat waste from cooling the ice is used to keep the arena warm. The iconic wood wave roof was built with one million feet of timber from trees killed by the pine beetle, the largest such usage in the world. The pine beetle epidemic that's ravaged the forests in British Columbia (more than14.5 million hectares) is itself a result of consecutively warm winters.
