I think where we see the biggest benefit is for larger buildings, of over 25,000 square feet. We have about 100,000 buildings like that in Canada, and there are huge gains to be made in terms of energy efficiency with those buildings.
There are three sectors: the real estate sector, the transportation sector, and the industrial sector. Typically the transportation sector makes changes, and there's a cost. It's the same in the industrial sector as well. The good thing is that in the real estate sector, there is not only a cost but a real return on the investment.
The real estate sector is starting to think a bit longer term, because these assets last for a long time so they are not for two years; they are more like for five to seven, and some of them are thinking about 10 and over 10 years now in terms of investing in their real estate portfolios, both from a carbon perspective and from an energy-efficiency perspective.
