The performance word, as blower door reading, is so indeterminate, that in fact only change of reading has meaning. This then mandates a "before" test, fudged as much as possible to be a high number, and, worst, serves as a preventive of air sealing. Someone seeing a problem can't fix it until its blower door consequence is recorded, and won't fix it, or does at five times the cost. If the fix will have no consequence to a blower door test, as with an attic floor pit, why bother? This is absurd. It is very costly in maintaining waste of energy.
I am heartened at finding a large majority of HVAC contractors warning of the misbehavior of BPI, and others, attempting to corrupt HomeStar legislation, for self-interest. I now feel freer to speak out.
I thought Bonneville Power Administration, Oregon and Washington had a lot to do with the BPI/ Home Performance phenomenon, nationally. I'm right about Oregon. Oregon is third in the nation, just a little worse than Virginia, in per-population acceptance of BPI certification. Most states have none.
And who is spreading it?
In Oregon, forced by publicly-funded BPA and its child, Regional Technical Forum, pressure to get with the program is intense. In Washington, it is only PTCS that has been enforced. I will hope to understand the forces for conformance in New York and New Jersey.
The claimed-biggest "trainer" is Everblue Training Institute, location unknown, perhaps Charlotte NC.

WellHome, Masco Brands:
Isn't that scary regarding intent to steal public resources through HomeStar?
