I'm going to come at it from a slightly different angle.
Every Canadian wants to live in a community that is safe and green. Whether it's for buildings or for infrastructure, if you go out of your way to make visible the state of that infrastructure as it is today, whether it's crumbling or whether it's low or high energy, people will make the choice not to live there and will force the owners of the buildings to actually do something about those buildings.
I'm a great believer personally in the fact that we need to have community report cards or some way of making this more visible to people so that people feel obliged to do it.
