What we're currently using here at the college, and certainly at other institutions, is based on a framework developed by the Sustainable Sites Initiative out of the States. With respect to a matrix of five categories—soils, vegetation, hydrology, materials, and human well-being and wellness—they've put a scoring system, where we can really break down each component of those five and evaluate the importance on a site, within a community, for example, a new site or a restoration, and link it against the benefits we're getting out of the project. We can spend a week going over what the Sustainable Sites Initiative group has done. They are folding their matrix into the Green Building Council in the U.S. I'm not sure if the Canada Green Building Council is also going to be adopting that. It complements what LEED has started.
In the LEED program, pretty much anything outside the building environment has really not been recognized, from an evaluation perspective. They talk about xeriscaping and some very basic water conservation practices, whereas with Sustainable Sites, we're folding in many layers that we can score and determine short term and long term, beneficially, how we can wrap it under urban conservation.
