Perhaps I could just add to that.
I have another hat, as a director of the Canadian Wood Council. We have done extensive research. When you talk about construction up to six floors, we have changes now to the national building code that provinces have been adopting. Here in British Columbia, almost all six-floor buildings being built now are being built with wood. That is a big market segment for us.
We've done market segment analysis on the sixth-to-twelfth-floor building segment. That's another building segment that is important here in Canada. It is probably even more important in the United States. We have a lot of effort going into the building codes around the sixth-to-twelfth-floor segment and into developing the technologies and building systems to meet that segment, because it is fairly significant. I don't have the numbers in front of me, but we can certainly get them to you. The Canadian Wood Council can get them to you as well.
We are also looking at commercial low-rise. A lot of these malls and things that you see that are done with cinder-block bricks and steel trusses could equally be done using wood construction techniques and gain the benefit of energy efficiency and savings in the carbon GHG world.
There's significant research on up to six floors, the sixth-to-twelfth-floor segment, and low-rise commercial. Those are the new segments that we as an industry are focusing in on beyond just residential housing.
