    Great, thorough article, Martin! It's not the sexiest building science topic out there, but it's certainly an important one. Now, about those ways of reporting air leakage, you mention cfm50 ...

    I like the bait stations like sentricon - compared to chemical applications. Would be cool to see an article comparing all the termite bait station systems. For example Whitmire Micro-gen has a ...

    I suppose that there are some areas where qualified contractors are in short supply. And there are certainly some owners who are capable of building a quality house, some even better than ...

    As a home owner who intends to build his own green home, I believe I am making the right decision to do it myself. Granted, I will have consulted with an experienced professional during the design ...

    I also want to build a green home and am not a builder. Probably the best way to learn more about construction and green building is to take your time and simply start reading. May I suggest the ...

    Oh, didn't see the assembly like that. Thanks Robert. I had assumed you could see the frost because you opened up and investigated a rafter cavity. Clarification here might help others help ...

    I am someone who makes a point to learn something new everyday, perhaps others should do the same. First of all not all open cell foams are the same, each mfg has of open cell foam has different ...

    I have some additional armchair building science observations. Your article did not discuss the source of moisture in the home. I would bet that a 5000 cfm50 house with high humidity levels is ...

    Doug, I do not understand How about an example?

    Ryan, before you add more insulation you should take the opportunity to dig around and seal up any air leaks in your attic floor. Anywhere wires penetrate and around chimneys are the worse ...

    I would agree with Carl where you have some flexibility on using the complete manual D program or an equivalent procedure (abridged version ) the requirement still exist in the current LEEDH version.

    Thanks Danny. I have to make sure it is appropriate for this location.

    I would only consider the use of an HRV in a 8,000 hdd climate, an exhaust only system will work in conjuction with the stack effect to keep the floors cold. If you get much beyond the 2 ach50 for ...
  • Jon Wyman | Feb 02,2010 09:58 AM EST
    Thanks for the responses. I am leaning toward the double wall with exterior wall sitting on the foundation and floor framing inset to deal with the thermal break problem. My cost comparisons ...
  • Lucas Durand - 7A | Feb 02,2010 08:57 AM EST
    Thanks again Robert. As an aside, have you ever heard of an exhaust only ventilation system that relies on chimney draft to pull air out of the house during the heating season and then switches to ...
  • Martin Holladay | Feb 02,2010 03:19 AM EST
    Doug, You'll need to answer a few more questions before we can help you. 1. What type of foam board will you be installing? How thick? 2. Where do you plan to put the foam board? Between the ...
  • Martin Holladay | Feb 02,2010 03:09 AM EST
    Ryan, 1. Either product will work. If it were my own house, I'd choose cellulose. 2. Remember, more insulation is better than less. As long as you're installing more insulation, you might as ...

    I do generally install a passive air intake behind the dryer but my flow hood testing of our houses that lack these inlets shows that air is getting in through distributed leakage to compensate ...
  • | Feb 02,2010 02:06 AM EST
    I wouldn't worry about the depressurization from an exhaust-only ventilation system, but with that running and a range hood (normal, not giant) and a dryer going, you're likely to generate enough ...
