Nick, if you want to know more about a poster you can click on the icons at the bottom. One will show bio info others may have a web site with links etc.
Continue your research, click at the bottom of ALL posters and good luck.
I am off shipping units now that utility bills are UP, but will reply with data to your questions so you can compare the advice.
One final point, the best home is one that has NO Delta P between inside or outside summer and winter! This home will reduce the possibility for Radon and Mold! I think that perhaps some of the posters must have "positive pressure somewhere"!!!!
