The auditor just left the house about an hour ago. The audit went very good I think. We found the areas that are problems, and will be able to start doing work this summer to fix it.
Of course, despite my work, sealing is still the biggest deal. With the blower door test and pressure set to 50 pascals, the flow rate was 2180 cfm. He thinks that with his suggestions I can easily knock that in half. Thankfully, my sealing upstairs did pretty good. There wasn't much leakage around the window frames/trim, just the windows themselves (cases) due to worn out gaskets. The attic access was also fairly well sealed.
The IR also did show that my 'double wall' wall (plaster on inner wall, intermedidate layer of lathe and plasters, then exterior sheathing) is horrible insulation. The joists are actually insulating better than the wall itself. So, insulation is a must up there. Also, the small angled portion of my ceilings upstairs are horribly insulated. I was pretty sure this was the case even when I did the attic insulation. However, I now have proof they're bad. The IR camera downstairs showed a fair amount of leakage around the window frames and door frames. That should be a relatively easy fix of taking the trim boards off and great stuffing around them. There is also some leakage between my 1st and 2nd floor which will probably be tricky to get to without having to cut into drywall. Then, there is the basement with a fair amount of leakage which was no surprise.
In any case, within a week I should have the full report and can post up IR images and other findings I've omitted. Overall, I'm very happy to have much better info on how to improve the house's efficiency and a good priority list as far as what will help the most.
The test cost me $325, and the guy was very knowledgable (30+ years of building/inspecting experience) and very helpful when I asked for suggestions on how to do this or do that. I would definitely recommend him to anyone else in the greater Milwaukee area. His website is
