I will certainly take you up on your offer to provide a long winded one, Carnak. You may think I'm off the wall, but I do enjoy the lessons you provide. The mid-Atlantic mixed-humid climate allows us to reap the "benefits" of multiple climates, depending on the time of year. While the forecast high on Monday is for the upper 20's, it was only a few months ago that we experienced the humidity of several sub-tropical storm systems. Don't ask what its like trying to grow grass here - that would require it's own discussion group.Originally posted by Carnak
You want to hear a long winded one from a guy who spent about 37 years in a cold dry climate and six years and change in a tropical climate?Originally posted by mjballweg
"Commercial buildings can typically have ventialtion systems that are slightly negative in the winter and slightly positive in the summer."
I've been wondering whether it would be practical trying to accomplish the same in a residence in a mixed-humid climate. It seems to me that there is plenty of info on maintaining a slight positive pressure during the summer but there doesn't seem to be much info on creating a slight negative in the winter. The potential consequences of being too positive in the summer don't seem to be nearly as bad as being too negative in the winter. It seems that ventilating with fresh air through the winter would create an undesirable positive pressure that you would try and control. Or, is this something that nobody should worry about? Any thoughts/ideas?
Maybe if I average them I can come up with mixed humid.
