Presentation by Randy Sharp
On February 21st, Randy Sharp, ASLA, will present a brief history of green roofs in Western Canada and talk about some of his award-winning projects including the Broadway Tech Centre and the Vancouver Island University Cowichan Campus. He will also talk about the Cascadia bio-region and ways to strengthen our north-south connections, discuss research, and share our collective knowledge.
Broadway Tech Centre
Broadway Tech Centre, an industrial brownfield site in Vancouver, features over 400,000 square feet of non-irrigated pre-cultivated extensive sedum roofs, and intensive rooftop gardens built over an existing warehouse structure. Water channels and cascades as well as continuous interlocking pavers and canopy trees provide a diversity of visual and auditory sensations in a productive and creative pedestrian environment serviced by SkyTrain rapid transit. The Centre was designed by Bunting Coady Architects, with ecological and urban design by Sharp & Diamond Landscape Architecture Inc,

The Broadway Tech Centre has won numerous awards, including an Award of Excellence from Green Roofs for Healthy Cities. https://www.canadianarchitect.com/architecture/broadway-tech-centre-in-vancouver-wins-green-roofs-award-of-excellence/1000330428/
Vancouver Island University
The green roofs at the Cowichan campus of Vancouver Island University cover over 90% of the building. Students observe the performance of six types of living roof systems including urban agriculture and a blue roof that supports sedges, rushes and Camas lily. Rainwater, not mitigated on the rooftop, chutes down vertical stainless steel channels into a large sponge park comprising wet meadows, wildflower berms, recycled concrete ledges and pathways. The campus is LEED Gold certified. For more information about the roofs and research, go to https://web.viu.ca/biomet/projectGreenRoof.htm
