On that relationship and what the CMHC uses currently, we spring off a number of different energy efficiency programs that are out there, such as BuiltGreen Alberta and R-2000. We've done the equivalencies between some of the commercial energy efficiency programs and the EnerGuide rating system that NRCan uses. If a person buys a house and it's R-2000 certified, say, that gets them a certain level.
We've done the equivalency across the different commercially available programs that are out there right now. All of those programs are ahead of the building code, so you're not getting an incentive from CMHC to be energy-efficient if you just build to code.
