    My apologies for the lack of detail or confusing format. I assure you that it's organized and detailed in my head. The main question is about using exaggerated ventilated rainscreen gaps in walls ...

    Passagyrs, Concerning the air sealing and ventilation questions: Assuming you can resolve the possible structural issues, the suggested air sealing and ventilation solutions are ...

    Jeff, I don't see a downside. Try it and see if it works. You can always add another minisplit in the dining room if you decide you need to.

    Russell, If I understand your roof plan correctly, here's my reaction: Yes, you can build an "over-roof" and insulate the new rafters with cellulose. If you do that, you would probably want to ...

    Russell, If I understand your question correctly, you are thinking of installing polyiso on the exterior side of your wall, but you are worried that the roof overhang is insufficient on one side ...

    Passagyrs, I'm guessing that your name isn't Passagyrs. Sometimes it's helpful in these online dialogs if you tell us your name. (I'm Martin.) I'm sorry to hear about your problem. ...

    Peter, We're both right. There is a shortage of skilled masons in the U.S. And there are a lot of skilled masons out there. Both of these statements are true. Builders who hire masons ...

    Kenneth, You wrote, "Further explanation is complicated and far afield ... It is not prudent to require double blind, evidence-based science in peer-reviewed journals before taking reasonable ...

    Alyssa, we have this same situation. We plan to use minisplits as our primary heat. In our case, we are not doing any dramatic 'ducting' to ensure the minisplit heating reaches distant rooms ...

    Wow, I have never seen an article here at GBA evoke such visceral responses (and ignorance sadly), especially from my heroes Dana and Martin. Clearly this is a hot-button, but you guys seem to be ...

    Super insulation may well become less of a desirable factor with increasingly affordable renewable energy sources available. However, the good air and water sealing techniques that contribute ...
  • Jon R | Jun 19,2018 09:28 PM EDT
    As we see more renewable energy and more time of use energy pricing, energy use (ie, kwh/year) will become an increasingly inaccurate measure of anything people care about (eg, $ and environmental ...

    Peter L, I think you put your finger on it in your description of old load-bearing masonry houses. Probably the reason masonry as a trade isn't as important as it was is precisely because it is ...

    Sure there are all sorts of questions around house size and it's implications on efficiency, resource use, etc etc. But if Armando's client base wants houses of a certain size, and the choice is ...
  • russell boudreau | Jun 19,2018 08:54 PM EDT
    I should add that the cellulose above roof sheathing is a semi rhetorical question but the concept remains for the walls. Its either foamless as much as possible or all in with full continuous ...
  • DAN VANDERMOLEN | Jun 19,2018 08:13 PM EDT
    I recently read that about half of all housing permits are issued for apartments and multifamily units. Are these units counted towards the average house size or is new living space actually much ...
  • Armando Cobo | Jun 19,2018 07:52 PM EDT
    Against my own judgment I'll comment on designing big houses. I've said this before... most houses I've designed are large custom homes that cost $1-5M to build in TX, and 3 times more in CA. But ...
  • Dana Dorsett | Jun 19,2018 06:25 PM EDT
    The older wood stove will use nearly twice as much wood per BTU delivered and won't heat the house as evenly as the hydronic system, but USD$15,000 buys a lot of wood (and even more chainsaw ...

    The Top 10 Hardest Jobs to Fill - The skilled trades rank high among blue-collar jobs that are hard to fill, according to the Manpower survey. Carpenters, welders, plumbers, electricians and ...
  • Peter L | Jun 19,2018 05:25 PM EDT
    Martin, Part of my comments were from the "cynical" part of me but the reality is, even based on the article you linked, it proves my point. That 22 teams from all over the USA came to Vegas. ...
