As the snow piles up outside, I have turned my thoughts to Spring. Not only because it’s warmer and nature is waking from it’s long slumber, but also because I hope we will be conducting our first blower door test by then. Specifically I’ve been considering what type of results I should be expecting from the blower door tests, and how to interpret them.
We made the decision early on to build an air tight house. This guided our choice of building materials, Zip system and tape for the exterior sheathing, gaskets and acoustical sealant to seal all other connections, and foam to seal gaps at the rims, windows and doors. The blower door test will help us seal any gaps we missed. But what target should we aim for? How do we know when the house it tight enough?
Today a local window repairman for Accurate Dorwin came out to fix our window woes. George, from Geo Glass in Vermont, seemed very experienced with our windows. He swapped out four sashes in a few hours and was busy adjusting the remaining windows when I left. He will have to return with some new parts to finish the job.
I’m putting together a list of all the known electrical appliances and devices in the house. One of the items on the list is lights. So I started looking around to see how many watts CFLs consume in comparison to incandescents. Then I came across this page…
