Let me try to complement what John said. From an NRCan perspective, when it comes down to the accountability associated with actual energy efficiency in buildings, we are really only accountable for our own.
We have 18 major labs across the country, a number of different ownership and occupancy arrangements, and we work within that milieu to drive the energy efficiency agenda.
We use some of our labs as living labs. We took over control of one of our laboratory facilities in Quebec, by example, and put it in the hands of the experts in energy efficiency—and I mean that in a scientific and engineering context—and drove the overall cost of energy down in excess of 45% and kept it at that lower level.
So in terms of our accountability from the energy efficiency implementation responsibility, that's where it begins and ends, as we are the occupants or owners of the buildings.
It's on the program and knowledge side where the products and services we generate are in the public domain. As I said in my introductory remarks, we function on our own for our own accountability for our own buildings. We function in collaboration with our colleagues at PWGSC in terms of making those services, knowledge tools, and programs available for federal departments who, like us, are accountable for their own. It's just that we have the expertise internally.
Then, primarily through Carol's shop, the Office of Energy Efficiency, but through other ways as well, we work with the commercial sector to enhance energy efficiency in buildings writ large.
