The thing is, for the retrofit case ("current house") it's a different ballpark of complexity. The thing is, there's no technical question about Ph levels - ALL houses should be built to that standard. The challenge there is political.
The technical challenges are in retrofit.
You might find Energiesprong (http://energiesprong.nl/transitionzero/) of interest - basically factory manufactured walls with joinery, move to site, crane on.

LEED is not my fav.
Yes, blogging is due, much to share.
Reducing consumption is first step, not getting caught up by what's cool is a big factor too. Rigor is required
Imo, air tightness trumps r value. Hard to do either consistently with traditional construction. Stay tuned I'll try to more on the blog.
Would be great if you had some blog posts about the decisions behind the engineering.
I'm pretty interested in this stuff and would be curious for example how you arrive at ZE given different consumption patterns with different people. I see a lot of people pointing at solar as their low hanging fruit whereas I'm much more of the mindset that minimizing temperature variance is much more important.
Doing pretty good with my current house already but would love to see more pointers towards a more rigorous approach towards insulation, air tightness etc.
