Green Roof research
Through its initial research, the Centre for Architectural Ecology established the stormwater, thermal, material, and acoustical performance of green roofs in the Pacific Northwest. The extent to which these systems serve a city’s ecological health remains unclear, however. In spring 2018, the Centre launched two new projects on the Elevated Lab, titled ‘Technologies and Ecologies’. For the ‘Ecologies’ section, the southern half of the Elevated Lab has been planted and sown with 18 species native to the Garry oak ecosystem of coastal BC. This urban ecology study will advance our understanding of the capacities of extensive green roof systems with respect to community ecology (plants, soils, pollinators), while advancing the practice of regenerative design for healthy cities and healthy ecosystems.
Many prescriptions for a healthy built environment tend to include green roofs, but rarely is the ecological function or type of green roof specified. Often, the roof surfaces are simply given as green-coloured, with no detail on material composition or habitat resources for native species. Funded by the internal Green Values Strategy Fund, this study aims to expand the framework of the International Ecocity standards (IES) to include the roles that ecologically functioning green roofs can play to the “long-term health of human and natural systems”. Can an extensive green roof be evaluated for its contributions to the health of a city?
