We've promoted, through what I refer to as good industry practice.... I think someone else on the panel has talked about the building code really just being a fairly low floor. The simple fact of the matter is that, in Canada today, homes that are built to building code aren't particularly efficient by any measure and we don't even have a way of validating the performance of that home. We have been promoting for a number of years creating a standard for the commissioning of homes so that at the end of the process, once the home is built, someone will actually go in and verify that the air distribution system is actually working the way it's designed to work. That's a comfort issue, but also an efficiency, a performance issue. It's not currently done.
