the house is leaking more air than is allowed by the passive house standard. i have been working to determine where the air leaks are.
my friend, ross shearer, and i worked today to seal off half the house. this is determine in which half the air leaks are worse.
the following picture shows what the temporary seals look like.
unfortunately, the tape that kept the large piece of plastic in place under the mini-split kept failing. i will try again soon.
the base-line on the house is 350 cubic feet of air leaks at a negative 50 Pascal. this comes to 1.2 air changes per hour.
