Indoor air quality in a ventillated NZE house when power goes out
We live in a NZE house of about 34795 ft3, and it has a ACH50 of 0.46 – the actual number was 269 cfm @ 50 pa. The Zehnder ventilation is set to 144 CFM. 4 bedrooms 3.5 baths.
If the power goes out, do we need to worry about suffocation? I would prefer not to open windows, to maintain the heat in the house for as long as possible. – the power goes out in the winter, usually. Has anyone done any studies on the indoor air quality in such a situation?
