Are you thinking of building something like this Paul? Or was this more of just an exercise in design? Good questions in your interviews as well.
I'm not sure who you were asking if we liked the article. I like it.. I'm glad I stumbled on your page in general. I just ordered rebel farmer from amazon.
I see mostly that your using a lot of oehlers designs of water management ( which you give credit for). I like all the idea's of plenty of light from all direction which is what were doing in our house project now, light from all 4 windows. Even with our attempt to be completely heated by the sun I felt that I could overcome the compromise of increased windows on the north side (going against the grain of conventional solar design) . Using cheap natural substances to keep price down.
The marriage of PAHS and Oelher is a bit tougher. I see your extending an umbrella out 20' however only downhill. I can see why your doing this as it you also went up hill I could see the potential for living in a pond
This of course will compromise the ability of the surrounding mass to moderate temp as the house is in direct contact with the flowing water coming from up hill. I'm sure you would still gain some benefits...my guess is that they would be diminished, to what extent is hard to say. You COULD run the umbrella ( Insulation and water membrane for everyone else reading
) however it would add a lot of excavation (but could be done!)
I don't see any earthtubes for ventilation. Is that something you decided against for your designs?
I hope that helps....? I like oehlers designs and haits so overall I like it. nice job.
