weird going on Gennaro.<br>
A one inch hole in the air barrier overwhelmed the minisplits? I
doubt that unless the air ea passing through the one inch hole was
moving at supersonic speeds or the minisplits had a capacity of a
few hundred BTU/hour.<br>

<pre wrap="">Here is a myth I believed was true:
Insulation is the biggest key to energy efficiency.
After building a Passive House in NY I learned it only needed
insulation to code - R18. What made it or broke it was how well the
6mil plastic air barrier was sealed. Just a one inch hole in the
plastic rendered the house unable to heat with the tiny mini-splits.
Seal the hole and you can heat the house with a hair drier.
That was a pretty crazy realization.

Hi, Reuben--
Amen!
May I add, Myth No. 6, Computer modeling during building design accurately
predicts actual energy reductions and performance of the constructed
building, and no monitoring or feedback is necessary.
