Growing the plants presented a unique challenge for Angela Anderson, head grower at Langley, British Columbia – based N.A.T.S. Nursery, the contract grower for the project. The integrated VCC team was committed to using sustainable materials in all areas of the project, including organic materials used on the green roof. The team decided that incorporating peat moss in the roof’s growing medium was not a sustainable option as peat-harvesting often disrupts delicate wetland habitats. The final substrate mix for the roof was a combination of sand, lava rock and organic material from the VCC’s own garden and kitchen waste and, as with Anderson’s propagation medium, did not contain peat. N.A.T.S. produced over 400,000 plugs and 80,000 bulbs over a 12-month period to accommodate the VCC’s staggered shipping and planting schedule, as well as 128 kg of seed which was hydroseeded after the plugs and bulbs were planted. The sheer number of plants involved posed some practical issues. Namely, how could the plantings be random enough to give a natural appearance but regular enough to accurately estimate the number of plants required? A solution was devised by VCC planting supervisor, Reece Rehm of Holland Landscapers. Rehm created a maneuverable planting template that consisted of a simple string-and-ribbon grid stretched between a twobuy-two meter frame made from irrigation tubing. With the help of Holland Landscapers’ Operations Manager, Jim O’Brien, who built the first prototype with his wife, Lynne, in their Langley, British Columbia living room. Rehm’s system could be easily moved and rotated to create a random planting pattern while also ensuring accurate planting proportions. “It’s hard to convey how important evenness and proportion were to the project,” Rehm says. “That the frame was a success is the thing I am most proud of.” Over a year after the initial planting of the VCC green roof, Hemstock is also pleased with the final result: “The fact that the project turned out so well is a testament to the cooperation from all the consultants and that the integrated design process really does work when it’s properly managed.” THE OLYMPIC VILLAGE The story of the Olympic Village’s combined 287,000-square-feet of green roof began collaboratively over 20 years ago and involved consultation with a wide spectrum of the community. With the successful redevelopment of North East False Creek after Expo ’86, Vancouver City Council set their sights on the creek’s south-east banks for the city’s next big transformation; in 1991, Council decided that the new neighborhood would be “the model of sustainability, incorporating forward-thinking infrastructure, strategic energy reduction, high-performance buildings and high transit access.” After a highly anticipated announcement in July 2003 by the International Olympic Committee, the South East False Creek (SEFC) Development Plan suddenly became the plan for the Olympic Village of the 2010 Winter Olympic and Paralympic Games. Arguably, this deadline would become the single greatest challenge of the project, making collaboration among stakeholders that much more vital. On top of the time constraints, the city enacted the SEFC Green Building Strategy in 2004 which set out sustainable goals for the village including LEED® silver minimum/LEED gold preferable standard for all buildings. Part of that policy required 50 percent of all roof surfaces to have green roofs; considering the Village’s eight city-block footprint (600,000-square-feet), meeting this requirement was no small undertaking.
