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

Take a Minute and Enjoy the Unfolding Spring Splendour of Sherway Gardens’ Green Roof

Next Level Stormwater Management was very honoured to kick off Sherway Gardens’ green roofs milestone 10th year by hosting participants of the Earth Tending Indigenous Green Infrastructure Training Program on May 23, 2024. The green roof tour was part of the week long training sessions led by Indigenous and non-Indigenous experts who “braid together Indigenous Knowledge with that of industry green infrastructure practices”. Earth Tending was created and is run by SpruceLab Inc. and sponsored by Miziwe Biik Aboriginal Employment and Training. Sherway’s 9500 square foot green roof was supplied by Next Level Stormwater Management and installed in 2014.

Earlier that day, Dr. Karen Liu provided an informative training session from her base in Vancouver, BC. Participants had great questions and comments. We look forward to more opportunities to learn and work together in the future.

Meegwetch to all participants, Gwen Lane and SpruceLab Inc. We feel very privileged to spend the day with you!
