I don't think it would be that be difficult. It does mean though that one has to do some research. They have to understand the systems that they're installing, they have to get good consultants, identify those good consultants who could help with specifying the right equipment, and also advising on how to put the systems together. It's like, for example, someone asking, you know, I wanna put in a high tech home theater experience. Well, you know, a normal contractor would just say, "Well, hmmm, am I supposed to go down to Radio Shack and pick those systems?" No, he would go and find a consultant who could help you, advise you on what equipment you should be putting in and how to assemble it.

So it does definitely take a--somebody has to be open to the idea of trying to create something that's green. And you know, a lot of them are doing really large, bloated houses. So there's a contradiction, actually philosophically for one, you know, for treading lightly on the earth and you're supposed to be like zero-energy gain, for example, and you're creating this 6,000-square-foot house. There's a little bit of a contradiction there. So I don't know how, you know, if a contractor is contracted to do a large house like that, you know, how one starts to make that greener.
