NLSM Team Celebrates Award-Winning BTC Green Roofs
Next Level’s Sasha Aguilera, Design Ambassador and Sawsan Hlal, Estimating and Operations joined Dr. Karen Liu, Green Roof Specialist on the Broadway Tech Centre (BTC) in Vancouver, British Columbia on World Green Roof Day 2024.
Designed by Randy Sharp and Connect Landscape Architecture, this award-winning, LEED Platinum certified campus was built on a former brownfield. Four of the eight low-rise BTC buildings are covered with a total of 10,000 square metres of lightweight soilless vegetated roof systems. They have a combined water storage capacity of 460,000 litres, or more than 1,500 bathtubs of rainfall (based on 300 litres per bathtub). Every year, the four green roofs absorb 10 million litres of rainfall, equivalent to four Olympic sized swimming pools, feeding the plants and evaporating back to the atmosphere, thus diverting it from our stormwater infrastructure. This thin-layered system has a superior water retention-to-weight ratio. It is comprised of locally grown roll-out sedum mats with 8-10 species of drought tolerant sedum. System base layers include mineral wool and fleece as retention layers along with a drainage layer and root barrier.
BTC is winner of the Award of Excellence, Green Roof For Healthy Cities and the Design Excellence Award, CSLA
