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.

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!

People just dont die in well sealed houses.

Well, many of these homes have propane cooking stoves (handy for power
outages) and AC powered CO detectors. Only the fire detectors are required
to have battery backup with low battery alarms. Houses sealed very
tightly.

Seems likely the average person might be tempted to use the cooking stove
since most furnaces need AC to provide heat. (Oil furnaces seem most
common). I haven't seen a ODP on a cooking stove yet.

A couple winter days without power might just be poor for one's health! I
don't think these codes mix very well when the power goes off.
