Now that I have the Blower Door and Manometer setup in the door and I have the home in "winter conditions" I can start the test.
I'm testing to see how leaky the home is and there are two ways to do this. The first method is to force the air out of the house. The blower door fan sucks the air out and the manometer gives a reading of how much air is being forced out. Basically I'm relieving the pressure in the home. The scientific pressure reading is calculated in Pascals of pressure. I can see your eyes rolling back - you don't need what a Pascal is just know that it's a sensitive unit of measurement. I'm relieving the pressure of the house down to a negative 50 pascals ( -50pa). This -50 pa is an industry standard pressure reading.
I simply read the cubic feet of air (cfm) being forced out of the home @ -50 pa and record that measurement. The cfm reading is on the right side of the manometer.
This reading is related to the volume of air in the home.
So I'm now off to measure all the interior rooms and spaces that are being heated or cooled i'll discuss that process tomorrow.
