David,
Here is a sample section of one of the footings (it will make sense to you!).
We are going up with CMU with the voids filled in, a Hambro poured roof. The walls and roof will have sprayed on closed cell foam insulation.
We are going for a very high "R-value" on the envelope. Also going with "low -e huricane" windows. MEP designed a modern HVAC system with ERV's and dehumidifiers. Very high SEER a/c units, low impact materials, .... (the high impact is on my wallet)
