It seems unlikely and undesirable and avoidable, esp in this country.
Canada's IDEAS (post R2000) air infiltration standard specs 0.15 m^3/h
per m^2 of envelope, tested at 50 Pa, which translates into a natural air
leakage of about 2.5 cfm, or 0.008 ACH for a 2400 ft^2 1-story house,
125X less than a typical 1 ACH US house.

Is that enough fresh air to sustain life? Would the oxygen deprivation
cause us to be come socialists? Enquiring minds want to know.


Maine requires very tight construction and power heat recovery
ventilation. My guess is they must have _some_ science behind it.

Not necessarily. politics + science = junk science

Sustaining life is an intriguing question, I wonder if they addressed it.
Since the ventilation is powered and extended power outages are common in
the coastal areas of the state!

Those who put energy savings first tend to fluff off the unimportant
stuff like health and comfort.

Possibly I am wrong on this, but quoting from the ASHRAE bible and
long involved formulas are not going to do much to convince me.
