Joe Lstiburek’s perfect ventilation system
I was reading an interview between Allison Bailes and Joe Lstiburek from July 22, 2013 called “The Ventilation Debate Continues” and in the article Ms. Bailes says:
“What about combo systems where someone’s using a balanced system for part of the ventilation and an exhaust for the remainder to meet the requirements. I’ve seen this in some Habitat houses where they’re trying to do balanced with the Whisper Comfort, Panasonic’s ERV, and it doesn’t quite get them to the 62.2 level so they put controls on the bath fan. So you see the Whisper Comfort, which is balanced but it doesn’t have distribution according to your definition, do you think that would count for distribution?
JL I’m assuming they’re going to have some kind of forced air as well, right?
JL So the mixing also provides distribution, right? They’ve got it all so they’re going to get the lower rate. That’s a phenomenal approach. So you basically put in that system and you provide a timer on an AirCycler to mix the air, that mixing gives you mixing and distribution. You get it all, and you’re going to get it at the lowest rate. To me, that’s the least expensive way to get everything. I think that’s a phenomenal system.”
I was wondering if this system applies to a whole house ventilation solution, or just for a bath fan? Are there any other components needed for a whole house approach?
Also, do you need to have a furnace and forced air ductwork for this system to work or can it be a stand alone system?
