PROJECT PROFILE ON THE ROOF WITH… GREENWALLSFORGREENERCITIES A SELECTION OF INNOVATIVE GREEN WALL POLICIES AND PROJECTS ACROSS NORTH AMERICA POLICIES VANCOUVER: The City of Vancouver’s 2020 Greenest City Action Plan has made energy conservation in buildings a key priority. Building operations generate 55 percent of Vancouver’s overall greenhouse gas emission footprint and the City’s green building team has developed a set of tools aimed at cutting this back significantly. One of these tools is passive design, which aims to conserve energy by reducing a building’s reliance on mechanical heating and cooling. The passive design approach harnesses climatic effects such as the sun and wind to improve energy efficiency. The City published two “Passive Design Toolkits” in 2009 to help designers and builders implement more passive design strategies in their projects. Vancouver also amended its Zoning and Development Bylaw to remove regulatory barriers to using specific passive design strategies, such as green walls. Conflicts may arise if green walls are designed to project into required yards and setbacks (the required distance between the building and the property line). To address this, the City’s bylaw amendment states that the City will allow green wall projections into yards and setbacks, provided that: (a) the wall is demountable and not permanently affixed to the building; (b) the wall does not exceed a 254mm projection. Hundreds of projects have been permitted through Seattle Green Factor since its introduction to Seattle’s zoning code in By: Rachel Moscovich, green building planner, 2007. Of these, dozens have included green City of Vancouver wall elements, with a wide variety of support systems and planting schemes. Cities around the country are looking to Seattle’s code and adopting similar scoring systems. Washington DC adopted a citywide version of Green Factor, Portland has Passive Design Toolkit: launched a pilot version, and many other municipalities are considering this approach.
