Open bedroom windows in a tight house
A general question. We are in the process of building an energy efficient house that will be tight and well insulated. My wife and I over the past 34 years have lived in Minnesota and now Montana. We have year around slept with a bedroom window open, including winter. I have been planning on having Panasonic bathroom fans regularly exhausting the house.
If we have bedroom windows open regularly and a regular plan to exhaust air out of the house, is that adequate in terms of air exchange? Obviously this is not as efficient as an ERV or HRV air exchanger but is it a reasonable plan understanding the lack of efficiency?
