BCIT’s Burnaby Campus is home to The Architectural Ecology Centre, where vegetation-growing roofs are tested, demonstrated, taught about, and improved upon.
Both durable and affordable, green roofs reduce storm water run-off, insulate buildings to lessen energy use, improve air quality by increasing “green space”, offer habitat, and more!
Vancouver green roofs reduce roof runoff by 28%, according to BCIT research. Wise water management means conserving by reducing use and wastewater production. Unabsorbed rain and other water is “storm water” that usually runs off roofs and pavement into storm drains. So, green roofs use water that could have become waste, and help reduce storm sewer discharge.
Storm water can contain oil, gas, sediment, fertilizers, and other contaminants. Heavy rains can overwhelm our systems and allow untreated water into streams. Storm water treatment also requires a lot of energy and infrastructure.
