Paul Morin replied to Griffin Hagle's discussion Which is the valid draft test?
"I agree that checking for combustion spillage is more important that checking for draft.  It is possible to have high draft pressures and spillage at the same time.  For example, if a 75,000 BTU water heater is vented with a 3"…"

Paul Morin replied to Evan Mills's discussion What kind of experience have folks had using blower doors in multifamily buildings?
"Hi Evan, there is a research project in the works that is being headed up by Ecotope and Center for Energy and Environment with some technical support from The Energy Conservatory.  They are looking at methods for code compliance air-tightness…"

Paul Morin replied to Griffin Hagle's discussion Which is the valid draft test?
"When testing draft, using the straight probe will be a close approximation of static pressure because the velocity is so low.  You should have the end of the probe close to the center of the vent and at a 90 degree angle to the pipe. "

Paul Morin replied to Pamela Brown's discussion Condensation on an interior wall of a detached garage.
"I agree with previous comments that the primary sources of moisture are the un-vented space heater and the slab.  But there could be additional sources.  It is not clear if this space is primarily a wood shop or a garage.  A wood shop…"

Paul Morin commented on Sean Maxwell's blog post The Better Blower Door Test for Multifamily Energy Code
"Hi Sean, Wow, 20 ACH50 is normal!  I have gotten calls for parts of Flordia where they have to use Ring A for the first time and are confused.  I thought that was bad.   We have had a distributer, Pro Clima, in New Zealand for a while…"

Paul Morin commented on Sean Maxwell's blog post The Better Blower Door Test for Multifamily Energy Code
"Thanks Sean for a very will stated article.  I agree with your assessment of the importance of compartmentalizing apartment units.  If the only focus is on tightening the exterior enclosure and leakage to adjacent spaces is not addressed,…"

Paul Morin commented on GEORGE LEVOSINSKI's blog post Blower Door DG-700 Meter drift
"Hi George, It sounds like you have a few things going on here.  If the DG-700 is not going to be used for extended periods of time, it is good practice to take the batteries out.   We recommend that the DG-700 be recalibrated every 3…"

Paul Morin replied to Stephen Standley's discussion Which reading is more reliable on a Minneapolis Duct Blaster?
"Sorry for chiming in so late.  Sean’s comment early on in the discussion was the closest to the point.  160 CFM is off the calibration charts on the high end.  Your Duct Blaster® Ring 3 may be able to top out at 160 CFM with…"

Paul Morin replied to George J. Nesbitt's discussion Duct Testing High Velocity Systems
"if the duct leakage is relatively low, 200 cfm or less, the pressure in the duct system will be quite uniform and either location will give consistent results.  If the duct leakage is high, over 500 cfm, we recommend that you do two…"

Paul Morin replied to Darrel Tenter's discussion Questioning W.C.C.

Paul Morin replied to Tim Marlett's discussion Blower Door Depressurization and the Human Ear
"This article (http://www.ncbi.nlm.nih.gov/pubmed/17587417) shows that the measured cabin pressure in an airplane changes by 5000 Pa during flight.  This will certainly cause discomfort but is unlikely to cause damage.  I wouldn't be…"
