Well, I think probably as with any industry it creates a lot of uncertainty. These individuals who work in that field are particularly.... They're essentially energy auditors. They're very skilled in terms of working with the builders, once the innovation and the new build is under way, to identify how buildings can really be built to high energy efficiency standards. While builders have improved, they still do lack a deep expertise on how to build better homes around environmental performance.
Essentially what happens is that they go into other jobs. Some have started working for us on our program. I think there continues to be a growth in that industry, particularly in new home construction. You have to really distinguish between those two. There's a demand in new home construction for their expertise, but the business in existing homes has decreased.
