Pog, I think sometimes you read attitude into my posts where none is intended and you come back with it in spades. If you open up a window or door, then that would be ventilation. If you keep it all shut up tight, then there is no ventilation unless a house is designed with ventilation. Most houses in Hawaii are designed with ample ventilation.

mdd, current code does not require double pane windows. Not sure where you're getting your info, but you can double check this if you have a copy of the codes, or by calling the building department directly.

We're at 2100' elevation and yes, it was cold outside. It was not cold inside, except the portion of our house that is largely outdoor. Even that was completely comfortable w/ a light sweater. As I've said, we recommend insulation for yurts mostly to keep it cool during the day. That insulation also works to keep the yurt warm at night. Weather called for 64 degrees for the low, didn't double check it though.

There is a thread on all this under the building forum. It discusses ventilation, proposed code changes and more. That might be the better place to continue code/building conversations.
