- turtlebits 2y agoIt is not - IRC (International residential code) requires whole house mechanical ventilation (like the forementioned ERV/HRV) if a house is measured at < 5 ACH50.
- anon7000 2y agoYes, and the article mentions the HRV and ERV systems these homes typically come with.
- mikeyouse 2y agoAir exchangers are one of the key HVAC considerations for passive houses... not sure how that could be considered overlooked. > Balanced Ventilation with Heat & Moisture Recovery > With an airtight enclosure, continuous, balanced ventilation is absolutely critical to indoor air quality (IAQ). Passive buildings continually exhaust air from bathrooms, kitchens and other areas with stale air and supply fresh air to living and working space https://www.phius.org/passive-building/what-passive-building/passive-building-principles https://www.phius.org/passive-building/what-passive-building...
