Follow on Google News | SEFAR® Architecture TENARA® Architectural Fabric is the Centerpiece of BC Place Roof ReplacementCanadian Landmark Features the World’s Largest Cable Supported Retractable Roof
The most prominent element of the new stadium roof is the inner, retractable TENARA Architectural Fabric roof that extends from the center of the stadium where it’s hidden inside of a pod above the videoboard to a fixed outer roof. The opening is 109 yards by 93 yards; the same size as the field below and takes about 20 minutes to open or close. The retractable roof consists of pneumatically- “SEFAR Architecture’ Revealing over 89,729 square feet of clear blue sky, the new retractable roof allows BC Place to tailor the atmosphere for any event. In the past, the facility had to turn away events due to the sealed air configuration that prevented natural light transmission and caused heat and humidity issues during the summer. Now, BC Place is equipped to handle summer festivals and concerts under the sun, football games under the stars, indoor exhibits protected from rain and much more. “The new retractable roof is an incredible feature of the newly revitalized BC Place,” says Howard Crosley, General Manager of BC Place. “Not only does it make a one-of-a-kind architectural statement, but the unique TENARA fabric also allows more light into the stadium than ever before. Ultimately, the roof gives us the ability to control the atmosphere at BC Place for any event – day or night, rain or shine – providing the best possible experience for our guests.” The facade is made from 144 transparent ETFE panels that protect the facility’s 55,000 spectators from inclement weather. The outer fixed roof is made out of 36 glass/PTFE panels. The new roof system is more energy efficient than the previous air-supported roof, saving the facility 25 percent on energy costs. The retractable BC Place roof features TENARA Architectural Fabric’s 4T40HF, which offers 40% light transmission. TENARA Architectural Fabric is woven from high-strength expanded ePTFE fluoropolymers, and is also fluoropolymer- “TENARA fabric provided the durability, strength and foldability that we needed for this ambitious pneumatic retractable membrane roof,” says Campbell. “In addition, TENARA has the high light transmission we desired for the retractable roof at BC Place. It greatly enhances the roof closed daylighting of the system.” “We chose to design with TENARA because of its folding capabilities and translucency,” BC Place originally opened in 1983 and was the world’s largest air supported dome stadium until it closed in April 2010 for renovation after serving as a venue during the 2010 Olympic Games. The $563 million revitalization project also included a new all-weather turf playing surface, upgrades to the mechanical, electrical, lighting and sound systems, enhanced entrances and concourses, outdoor landscaping and replacement of 50,000 seats. The facility is the largest sports, exhibition and entertainment venue of its kind in British Columbia and home to the BC Lions Football club and the Vancouver Whitecaps Major League Soccer franchise.
