I can start.
I know you've heard from witnesses who have spoken about Green Globes and BOMA BESt and LEED. We have looked at the various standards that are out there from our perspective, and have chosen ones that we feel best suit our portfolio.
But your question is very apt. Work has been done at the National Research Council to evaluate whether LEED projects realize the objectives they have set at the start. While in most cases they do, there are other cases where they do not.
This is still something we are working towards evaluating. We do collaborate with our colleagues at NRCan to look at what is the best tool, at what is the best way of assessing the objectives and the accomplishments of these projects.
