Green Roof On One Of Toronto's Subway Stations

In a recent article on Crisp Green, we see that Toronto is following in the footsteps of cities like New York and Chicago, by introducing a bye law that requires green roofs to be installed on industrial buildings that are over 2000 square meters. The regulation requires that between 20 to 60 percent of the roof area should be covered, depending on the size of the total area. Between 2009 and 2010, Toronto had already introduced bye laws that included residential and commercial areas of that size, and is now targeting the industrial sector.

At first glance, this seems to be a very good idea. There are endless ways in which green roofs contribute to the environment, the cities and the people living in them. Green roofs provide insulation against the elements, providing heat in winter and cooling in summer, resulting in significant reductions to utility bills. The vegetation absorbs rainwater, so it is not wasted on the city’s pavements on its way to the sewer. Rain water can also be collected, and stored for better use, should the owner be so inclined. The green areas provide a space for city dwellers to re-discover nature. It provides a peaceful space for them to retire to, and get away from the pollution and hustle and bustle of the city.

Having said all this, however, should these green roofs be imposed on people? Perhaps the only disadvantage to owning a green roof is the initial cost of installing it. If maintained properly, a green roof can last for years; however, the initial set up could be prohibitive. The bye laws in Toronto apply to new construction, and therefore the cost of the green roof can be included in the overall budget. It is understandable, however, that this may be an added and unwanted cost for some people. As much as we wish them to be, not everyone is willing to spend the extra cost for the sake of the environment.
