With respect to my point earlier about the Europeans, people have already mentioned that the Europeans have adopted a system where they have a target of so many units of energy per square metre, and each building has a label under its building code. I don't think they have any technology that we don't have. I don't think that's a limitation. I really don't know how to address your question, other than to say that I think everything's available to us that would be available to the Europeans. We don't have that approach, the building labelling approach. Maybe something like that instituted in Canada, along with our codes, would be helpful. I think the next version of the National Energy Code of Canada, in 2015, will likely have building targets.
