πŸ’¨πŸšͺMeasure the envelope

You can tighten your building envelope by air sealing your house.

  • That’s the first step toward controlling temperature, humidity and air quality.

πŸ”Ž Between the lines: Measuring the leakiness of your house gives you the knowledge you need to make changes.

πŸ‘‰Β You can know how leaky your house is compared to current new construction standards.

πŸ‘‰Β You can see exactly where your house is leaking.

πŸ‘‰Β You can verify the effectiveness of air sealing by measuring after sealing is done.

βš™οΈΒ How it works: We use a special fan and computer to depressurize the house.

  • And measure how much air the fan has to move to maintain that pressure.

πŸ₯Β Introducing: The Blower Door

  • A blower door score is expressed in ACH50 β€”> new construction homes should have a score of 3 ACH50 or less.
  • ACH50 = Air Changes per Hour at 50 pascals.
  • In other words – with that pressure difference between inside and outside your house, the air inside the house would be replaced 3 times if your blower door score is 3.

🧠 Think about it like this

  • If you added up all the little leaks in your house
  • You could compare it to a single hole in the side of your house

😬 My leaky old house has a hole in it the size of soccer ball!
