Blue Boat Home learning to live together sustainably

Based on my answers to the client survey, the computer spat out a calculation of how much leakage our house needs to supply enough fresh air to the people who might occupy the house: 1.1 square feet, as it turns out.  That is, if we sealed all our leaks, we would have to leave a window open so as not to suffocate!

However, the blower door test soon demonstrated that we currently have 1.7 square feet of leaks, so we can (and should) safely close up 0.6 square feet of leaks, focusing on the ones that are not around doors and windows.  This seems counterintuitive, but the leaks around doors and windows let in better air than the ones in the ceiling, floor, and interior walls.
