    Thanks Dana. In regards to my R-30 comment I would only install that on the above ground section and leave the foam and R-15 fiberglass below. On a different note Emmy whole house has faced ...

    Basement wood stoves are even trickier, since the firebox is lower in elevation than where the combustion air has to enter the house, so there's a natural bit of stack pressure working against you ...

    Thought I’d try once more, as I continue to strike out with the local lighting company. I have six 8 inch cans in a sloped, cathedral ceiling. Thanks to all of the input here, I finally found ...

    TKAJ: Both Home Depot & Lowes carry a selection of Type-I EPS with facers. Menards sells Type-I EPS with and without facers. Type-I is fine for the wall foam- it's easier to air-seal with tapes ...

    Made me laugh.

    Forgive me, I realize there are legitimate issues here but I can't help finding the notion that the US military can't deal with the existence of wind farms rather amusing. Picture for a moment, a ...

    The warm-glow dimming is something I personally don't care about, but some people do. It's good to know that they've engineered a product to meet that market! Thanks!

    Depending how high your concrete wall is, you could stop the lower framed wall at the concrete wall height and create an artistic ledge. Its a good ledge to place pictures, household ornaments, ...

    Andy, As far as I know, the amount of evidence showing health benefits from HEPA filters attached to air handlers is the same as the amount of evidence showing health benefits from HEPA filters ...

    Something I didn't see here was if there is any scientific evidence that high performance filters (HEPA and otherwise) in air handlers and ventilators have significant health benefits? Or is it ...

    My ceiling cassette shoots about 30’ no problem cause any unevenness eventually levels itself out. Regarding the space not sure if trusses can be cut, I don’t think they can but I’m no engineer. ...

    Chris, The upstairs rooms will be the kids (ages 4 & 5) room and we plan to leave the doors open most of the time. Originally I had planned to use a ceiling cassette but the roof trusses are ...

    Randy, this sounds like a very cool home. I have never heard of that Steffes thermal storage furnace before. I would like to see one of those up close. Thermal storage techniques may be ...

    Dana, Thanks.

    Similar to Chris I'm using a single head per floor, ~1200sqft per floor. I have 2x6 walls with only cavity insulation, and R20 wall insulation in the basement, but no slab insulation, and R60 ...

    Jill, Your energy costs are low. For you, burning natural gas is significantly cheaper than heating with electricity. Natural gas at 80% efficiency: For 100,000 BTU, you pay $0.63 Heat pump ...

    I'm almost convinced that it can be done most cost effectively with 11 7/8" I joist. Using I joist allows the air barrier to be installed from above so it can easily include taped "house wrap" ...

    Would the upstairs bedrooms doors be opened at night? A single mini split ceiling cassette should be able to cover them assuming the house is insulated and air sealed properly, having a hard time ...

    Can you make a BEOpt model? It's free and fun to use. Once you build your house you can tinker with systems.

    Dana, Thanks for the long answer. I think I understood most of that. First, I did have someone from a company that does energy ratings do my manual D/J. He came up with total loads around ...
