green-friendly? I want to make a "Green" hotel that is nearly 100% organic.

Any materials as to beds/walls/paint/restaurant/location/water-conservation/products to use that I could use? I read an article on how hotels should, instead of being a 'machine', be part of the earth itself. And by that, I mean consuming and/or expelling earth-friendly, biodegradable material.

Plus, that would be great if an answer included things that were (dareisay) cheaper in the long run, and that would be not so much of a burden so that I am spending FAR more than I am earning.
