1. Yes, blower door tests are sometimes performed on sections of a building. You could certainly perform four (or more) standard blower door tests--one at the beginning as a baseline, and then one more following each phase of work. That would give you fairly good info on what you accomplished with each phase, and I would certainly do that.
Chapter 2 of the Minneapolis Blower Door User Manual. • Prepare the building for the blower door test. For instructions about how to do this, please see Chapter 3 of the Minneapolis Blower Door Manual. Tubing Hookup 1. Attach one end of the red tube to the Channel B input tap. Attach the other end of the red tube to the pressure tap on the
A Blower Door Test is undertaken by installing a specially calibrated fan in either a window or door of a prospective eco home. This fan is supported by a fabric surround that seals the whole opening. The fan pushes air into the house and pressurises the building to 50 Pascals (this is the 50Pa part of the two measures).
The Blower Door test simulates the following: If a home has wind blowing against it at 20 miles per hour, the total volume of air within the house would exchange with outside air 7 times. The 20 mph wind is equivalent to 50 Pascals (Pa) pressure difference that we are simulating using the Blower Door Fan. All homes are tested at this 50 Pa
Check out how I tested the blower motor resistor at the bottom of the article—you could do the same and check for any O/L readings. If anything looks awry, I checked SummitRacing.com and replacement blower motor resistors for a 2007 Passat are priced pretty reasonably—and since you’re already got the blower motor out, it’d probably be a
