Square metres. That's a staggering amount.
I think I've asked you these questions in previous estimates, but I'm still interested in and frustrated by the fact that we're not taking radical measures to reduce our operating costs in terms of energy use. I'm speaking specifically of the federal buildings initiative.
Our research shows we could harvest units of energy and reduce our operating costs out of the existing system by demand-side measures, by comprehensive energy retrofits of all this space you use, not only to reduce your operating costs but to serve as an example to the private sector of what can be done if we develop that expertise.
Can you give us any update on the efforts you've made? First of all, what is roughly the amount you spend per year on energy—heating, cooling, lighting, water, etc.—and what active steps have you taken to reduce those costs?
