I find that, particularly in the commercial and higher education institutional environment, the fact that we have buildings that are at a point where we need to renew major parts of that system gives us an opportunity to really stop and ask how we can make this a better environment and not waste the energy.
I do see that there's a lot more interest in that. It's kind of the one extra thing or the one extra opportunity that happens just on the basis of the age of the built environment that we're dealing with.
