Daniel Baur-McGuire replied to Steve Nations's discussion high rise humidity
"Do a duct test. Total Duct Leakage! Measure RH at return and supply. Verify humidifier is on. If that humidifier is working you could be pumping humid hot air into building cavities.  A recipe for mold and mildew"

Daniel Baur-McGuire replied to Kyla Marie's discussion HOT2000 - supplementary heating not being taken into account
"This screams oversized! Why the two furnaces? Split system for two floors? I would think 2 furnaces would use more energy than 1. As you have to start up and power two blowers now. Sorry not familiar with HOT2000. Good Luck! "

Daniel Baur-McGuire replied to Jerry Needham's discussion 70 unit building rehab
"50K is not much to work with. I would look to air seal units. It will also improve sound and smell transfer between units. 2nd I would look to HVAC for comfort. HVAC and Air sealing usually solve many comfort issues. Is the HVAC system ducted? if so…"

Daniel Baur-McGuire commented on David Keefe's blog post Explaining Air Sealing and Ventilation to Homeowners
"Awesome write up. Very well done and to the point. Always someone who wants to challenge this with the "Homes need to breathe" comment. I think it means, "I just want the status quo so i can be lazy and cheap.""

Dave Taylor replied to Daniel Baur-McGuire's discussion Cross-laminated Polyethylene vs non-cross laminated
"I use 20 mil poly on my crawlspaces and now a high traffic 90 mil has been added to the marketplace. Usually they have a scrim fiber between layers to resist tearing. Remember a 1/2" hole negates the purpose of sealing in 1500 ft. so the better…"

"Thanks Dave Taylor, I figured it had to do with tearing resistance but I was not sure."

Dave Taylor replied to Daniel Baur-McGuire's discussion Cross-laminated Polyethylene vs non-cross laminated
"Daniel, Cross laminated poly has a higher tear strength but you should use 10 mil or greater or it's a waste of time,they tear to easy and defeat the purpose of the install."

"Closed, conditioned crawlspace. Not high traffic, I would say no traffic. It is a half basement/ crawl. closed cell spray foam on crawl walls, poly will be sealed w acoustical sealant. I am planning on 10 mil poly and the contractor wants to use…"

David Butler replied to Daniel Baur-McGuire's discussion Cross laminated Polyethylene vs non cross laminated
"Are your referring specifically to a closed crawl space? It makes a difference in the thickness necessary to maintain a good air and vapor seal given the potential for foot traffic."

"I have done this before. We did not use hydronic heat or radiant barrier. We used all EPS foam leaving a small half inch gap between foam and wood framing to foam in w a can. Yes we cut and filled the whole framed cavity as well as a 2" EPS…"

Daniel Baur-McGuire replied to Tim Kendzia's discussion Cooling effect from solar panels
"I would argue that keeping the solar panels cool is more important as you will produce more power. Adding heat adds more resistance on the electrical system decreasing efficiency. I would go for a larger air gap. A study was just done in Des Moines,…"

Daniel Baur-McGuire replied to David Meiland's discussion Air gap above floor insulation--how big is the impact?
"Im specifically thinking of floors over garage. Builders here often use rigid insulation under the FOG. Or, most out builders do blown insulation to meet the substantial contact rule. That's what we typically see in my area. Last "crawl…"

Daniel Baur-McGuire replied to David Meiland's discussion Air gap above floor insulation--how big is the impact?
"Where is this written? please and thank you. As, its written you would have to do cont. insulation on the underside of the floor in order to be able to ignore the "6 sided substantial contact code"?"
