Looking east from the seawall with the Vancouver Rowing Club to your right, you first feel the presence of iconic Stanley Park at your back. As the park wraps around you, heading in the direction of downtown, your eye follows the stroke of green that the garden-infused seawall creates. This line continues unbroken along the water’s edge and ends at the slopes of the VCC green roof, a broad meadow rising effortlessly from the shore. The visual weight of the roof balances one end of the greenbelt against the massive park on the other; Western Canada’s largest city fills the spaces between, making this connection simply remarkable. The VCC expansion, completed in April 2009, served as the International Broadcast Centre for the 2010 Olympic Winter Games. Located at the eastern extreme of Coal Harbour, it is the final touch to a 20-year transformation of this previously industrial neighborhood. Designed by Seattle-based LMN Architects in conjunction with two Vancouver firms, MCM Partnership and DA Architects & Planners, the VCC expansion effectively tripled the existing conference centre’s functional capacity. The size of the project team was similarly impressive, so much so that several conference rooms at the VCC East facility, more commonly known as Canada Place, had to be rented to accommodate the 50 to 60 consultants required at any one time for design meetings. It was during these charrettes, says Mark Reddington, design partner at LMN, where the VCC green roof was first conceived. “The idea of the green roof came about as the result of integrated thinking because it could address many different issues simultaneously,” Reddington explains. By gathering all of the experts into one room, issues from energy efficiency to water management to float-plane noise arising from the adjacent Burrard Inlet terminal could be evaluated by everyone. “During the design process, you look for intersections,” says Reddington. “The way you solve one issue might be able to solve another. If you can solve them all by a single gesture, then it really is an integrated result.” While the conceptual idea of a green roof was one thing, the actual practicalities were quite another. Robert Simpson, senior engineer of Glotman-Simpson Consulting Engineers, reflects on the first hurdle the team had to overcome: “[The green roof] required buy-in and understanding from a very wide range of project participants. As a prominent component of the building, every consultant had some connection with this roof solution. ” Once everyone was on board, more in-depth problem solving among team members could begin. For example, Glotman-Simpson’s recommendation to use an extensive system with six-inch compacted soil depth could not be made by the engineers alone: all players needed to be involved as this one decision would inform the rest of the project. Paul Kephart, of Rana Creek Habitat Restoration in California, said to the VCC team at the outset of the design charrettes: “This project is all about water.” Climate is always a consideration for green roof design, but water management on a six-acre roof between Vancouver’s drought-anddownpour conditions became an exceptional challenge for the VCC team. The key-line drainage system that was chosen, designed in conjunction with PWL Partnership in Vancouver, consists of aluminum-edged, rockfilled runnels that crisscross the roof diagonally, slowing stormwater and directing it into a conventional drainage system. The drip-irrigation system, which utilizes treated VCC blackwater from an onsite facility as its main water source, is activated only when moisture sensors in the roof
