BC Place Stadium, BC Place is busy with over 200 event days per year and contributes over 40 million dollars per year in economic benefits to the Province of British Columbia. It hosts the Province's largest trade and consumer shows, community events and motorsports. BC Place has been the home to the CFL's B.C. Lions since 1983. It is covered by fabric that is 1/30 inch thick but stronger than steel.The roof sports 10 acres of fibreglass woven fabric. There are 2 layers of fabric with a 4 foot space between them. When it snows, hot air is pumped between these layers to melt 6 inches of snow per hour. The roof lets in 20% natural light. That's because the total thickness of each layer is only 1/30 inch (0.85 millimetres). The heartbeat of the building is the air-support system of the fans. Sixteen fans were used to inflate the roof...in less than 1 hour! These same electric powered fans keep the air pressure inside the stadium at a higher level than the air outside. This extra air pressure is the only thing keeping the roof up -- there are no beams or steel used at all to support it! If the fans were turned off and the doors shut, it would take 4 - 6 hours to deflate the roof. Return
