If I might add to John's response, I can give you another example as well. You may remember that NRCan was asked to move its materials technology laboratory from the Booth Street campus in a fairly old facility to a brand new one in Hamilton, on the campus of McMaster University in their Innovation Park. That building is on track to achieve a LEED platinum status. It jumps from gold to platinum because it does all the things that John's talking about in the example he gave, plus there are boreholes in the ground where heat and energy that is not needed in the summertime is stored and then drawn back up when it is required in colder weather.
We haven't gone long enough yet to confirm that this will be the case forever, but the early calculations indicate that the borehole storage will in fact do more than the building requires, and it will be able to actually help support the energy needs of the innovation complex at McMaster University. So there are a number of innovations associated with the kinds of buildings we're talking about that can be used as examples.
