Green Building

I would like to ask what products people have had good luck with building a green or even leed certified house. Everything from the foundations to the floors and counters. Anyone with some good experiences please share. Insulated blocks I have heard good things about. What do you think about the costs ? are they close or is one way actually cheaper then the other? Solar anything is too expensive for the average homeowner isnt it? If there is an affordable solar heat or water solution id like to hear about that too.
