We did our first blower door test
on our Madrona St. project today. We were shooting for under 1 air
change per hour at 50 pascals negative pressure. This is a very tight
building. Well we hit it and then some. Readings in the .8-.9 ACH range.
This is excellent, especially since we still need to do the blown in
blanket insulation and drywall!
Why does it matter? Air leaks are largely responsible for energy
loss. It is why a home loses heat, feels drafty and how allergens can
enter your home.
Robert Stockman of Pinnacle Inspection did the test for us. He is also doing third party verification for Built Green, NW EnergyStar, and LEED certification on this project.
