Yes, if I could. It's an interesting situation, because under the budget announcements we will be reducing the amount of floor space that we occupy and, through the introduction of our Workplace 2.0 initiative, we will be increasing the density. So building energy consumption, as you can imagine, for cooling in the summer and the operation of elevators and escalators will actually be increasing. You may look at a building trend data over five years and ask what happened, because their energy consumption's gone up despite various initiatives, but the density of the buildings will be greatly increased. Overall our footprint will be less, so our total consumption will be less.
