Nick Pine  . . . Did you start this thread all about Energy
Consultants?

I'm a learning "energy rater" for Energy Rated Homes of Colorado with
a real world question regarding infiltration.   I say I'm learning as
I've only been dealing with heating and A/C for 30+ years.

In the course of performing Manual J (ACCA) heat gain and loss
calculations I am finding great variances in opinions as to what
should be used  for infiltration figures.  Do you or any others
lurking here have experience using blower doors to measure
infiltration into houses?  AND if you do what do you/would you use as
the infiltration, air changes per hour, into a house if you find that
a 24,160 Cu. Ft. house leaks 3,200 CFM at 50 pascals  negative
pressure?

Using the Manual J detailed infiltration estimate method I come up
with winter AC/Hr = 0.85 and summer AC/Hr = 0.32 AC/Hr.
