    Joe, I thought this was an interesting question. I live in a mixed climate and the forced air HVAC systems that we typically use are costly, big honkin "monsters". I would think that a well ...

    well, ummm,....this is just something to ponder for the "Einstein Charlie" in post #10. Not sure if it was an innocent typo but when you come across sounding like the way i took it, you MIGHT want ...

    I recently removed, repaired and repainted a 100 year old historic church. The process I used was 90% prep and very labor intensive but very rewarding completion. I used an Infrared heater and a ...

    The PH discussion about fireplaces and pellet stoves further supports my contention that such sophisticated technological life support systems with so many potential failure modes belong in outer ...

    Thanks Daniel, that is a good link I was not born with an attraction to fire.... But I realize that many, many people really,really like fire I also realize that some people have access to ...

    In the interest of sharing, I found this post on the Passive House forum: http://www.passivehouse.us/bulletinBoard/viewtopic.php?f=6&t=123&st=0&sk=t&sd=a&start=20 Katrin has some detailed ...

    Why don't you spray low density foam over the sacrificial mortar. The foam allows vapor to pass inwards so the sacrificial layer still works but now you don't have a mold risk with the panels. ...

    Maybe we should post a new question. These older posts don't get any traffic. Possible Titles: Double-Stud wall vs. Exterior Foam insulation. Which is more durable? Are Passivhaus Walls ...

    John - Now I get it . . . I'm going through an internal debate right now. I see these Passivhaus projects using extremely small quantities of heat. If I run the calculations it seems like a ...

    John - I'd like to echo Peter's note, perhaps even give it a twist . . . Your question is at the heart of what I'm trying to understand about the different techniques. Each has its own risks. ...

    Martin, I agree that if this is a series of small brackets and not a continuous steel angle.... It is not-so-bad It was just not clear from the illustration. Are there any photos of this detail?
  • John Brooks | May 15,2010 02:02 PM EDT
    Daniel, I know..... I am fireplace and woodstove phobic. I tend to think in extremes and worst case conditions. I thought Michael Blasnik and Robert's comments were both excellent. In the ...

    John - I'm not sure about the context of your statement (or mimicry). Michael provided a very specific answer that was well stated. It's a joy to me to find such intelligent and experienced ...

    John, Joe's "Clint Eastwood" examples -- the bad and the ugly -- show continuous steel brackets continuously attached to a concrete slab at room temperature. I think it's a stretch to say this ...
  • Martin Holladay | May 15,2010 10:32 AM EDT
    Mike, Check the specs: mechanical ventilation is provided by a Renewaire energy-recovery ventilator. Since the roofing is standing-seam metal over SIPs, I don't believe there is any roof ...

    Joe, Thank you. I think I'll put the sacrificial layer on the inside and not worry about capping so long as I don't see efflorescence on the exterior. My basement has wood paneling on 3 of ...

    Wondering what ventilation systems were used on this project.; both IAQ and roof ventilation, etc. used?
  • John Brooks | May 15,2010 08:00 AM EDT
    If the steel angle is not continuous then it seems to be "not-so-bad" If it is continuous ... then what makes it any different from the "bad" example in the Clint Easwood anology in Lstiburek's ...
  • John Brooks | May 15,2010 07:38 AM EDT
    Now that's what I'm talking about! Awesome. Thank you ROBERT. Thanks for addressing the the closing remark in Daniel's question.
  • Martin Holladay | May 15,2010 05:21 AM EDT
    Greetings, fellow Martin! If you tell me your last name, I'll be able to report you to the Federal Trade Commission for your blatant violation of the Federal R-Value Rule. If all goes well, ...
