It’s surreal when you come to the realization that you want to move back home to the small town in which you were raised…

Rough in DWV system complete . . . All drain piping is complete, other than the connections to the bathtubs and shower. We decided to go with @geberit_usa in-wall toilet carriers for three of the smaller bathrooms, so we’ll see how those workout. Anyone have any experience with them? Last couple pics show the recessed box option for the Studor AAVs. The finish faceplate is super slim, and paintable, so I’m guessing this should blend right in. It’s also in the top corner of the toilet nook in the master bath, so no one will really ever see it. Supply plumbing starts tomorrow . . . #beartoothpassivehouse #beartoothph #beartoothphcc #redlodgepassivehouse #highperformancehomes #montana #redlodge #myredlodge #passivehouse #passivhaus #runwildbuildpassive #plumbing #inwalltoilet #dwv #drainwastevent
Air admittance valves . . . From the research I’ve done, it seems there are typically strong opinions for, or against, AAVs. A lot of state codes only allow for a limited number of AAVs to be installed in a building, and even then, there are pretty strict locations in which they can be utilized. However, I have found no logical/practical reason, other than codes (not that those are always logical...), that using AAVs throughout the house would not work. They allow the number of penetrations through the building envelope to be greatly reduced, which is a huge benefit in airtight construction. Montana does not require a plumbing permit to be pulled if a homeowner is installing her/his own plumbing, so we’ll be installing a number of AAVs throughout the home. The most efficient use of an AAV is through a horizontal wet vent used to vent one, or even two bathrooms, but layout doesn’t always allow for that set up. We’ll be using a couple in the horizontal wet vent application for bathrooms, but then we’ll also be using others in more typical dry vent applications, as well as to vent the washing machine drain. Like it? Hate it? Would love to hear feedback/discussion . . . #beartoothpassivehouse #beartoothph #beartoothphcc #redlodgepassivehouse #highperformancehomes #montana #redlodge #myredlodge #passivehouse #passivhaus #runwildbuildpassive #plumbing #studor #airadmittancevalves #aavs
Last load of Rockwool insulation . . . I’ll have to total the exact bag count once we’re all finished, but I believe this puts us somewhere close to 15,000 sq ft worth of batts for 2,500 sq ft of wall area (you’re welcome @rockwoolna 😉). 5 layers deep in the walls gets us right around an R-60 and the cellulose in the attic plus the Rockwool batt in the ceiling service cavity puts us at just over an R-90 overhead. Add to that some Safe ‘n Sound in some interior walls and the first floor ceiling and the place should stay comfortable and quiet all year long . . . #beartoothpassivehouse #beartoothph #beartoothphcc #redlodgepassivehouse #highperformancehomes #montana #redlodge #myredlodge #passivehouse #passivhaus #runwildbuildpassive #insulation #rockwool #mineralwool #battinsulation #warm #comfortable #quiet
Long time since the last post, but I’ve been staying busy . . . I’m no electrician, but I’m pretty dang proud of how this panel turned out. Didn’t take terribly long to make it neat, and it was great to find inspiring posts on IG to help as examples. @zehnderamerica ERV system install nearly complete. Just have a little additional insulating to do on the intake duct and then need to run the PEX lines to/from the ComfoFond . . . #beartoothpassivehouse #beartoothph #beartoothphcc #redlodgepassivehouse #highperformancehomes #montana #redlodge #myredlodge #passivehouse #passivhaus #runwildbuildpassive #sparky #electricalpanel #breakerbox #erv #ventilation
Great training is the basis for great results . . . This was me about a month and a half ago discussing our Passive House project (the first PHI-certified home in Montana) with a group of builders in Bozeman, MT. A couple weeks before this, we had just hit 0.17 ACH50 on our initial blower door test - quite possibly the tightest house ever constructed in the state. My real PH journey started nearly 2 years ago to the day when I took the week-long Certified Passive House Tradesperson from @emubldgscience . I learned a ton in the class and met some great builders who I still stay in touch with today (@living_craft ). Over the last two years, Emu has continued to adapt and tailor their training to the North American construction market. If you’re interested in the training, the next session is in Denver from May 20th-24th. The link to the registration is in my bio, and feel free to use code EMUBEAR for discounted pricing. Just wanted to say thanks for the last two years, Emu! Can’t wait to see what the future has in store... . . . #beartoothpassivehouse #beartoothph #beartoothphcc #redlodgepassivehouse #highperformancehomes #montana #redlodge #myredlodge #passivehouse #passivhaus #runwildbuildpassive
Wood stove in a Passive House? Yes, it can absolutely be accomplished . . . There should be no reason that a wood stove cannot be installed in a very airtight home. It takes a little foresight and some thought on a couple key junctions, but it’s not hard. The major components of our Hearthstone wood stove are nearly complete. The stove is located on the first floor, and the chimney runs straight up through the second floor system, then straight up through the ceiling air barrier on the second floor, then into the vented attic, and finally out through the roof. In my mind, the key connections are 1) the stove pipe to chimney pipe transition (pic 3), 2) the chimney penetration through the ceiling air barrier (pic 4), and 3) the outside combustion air penetration through the subfloor air barrier (not pictured). I’ll go into more detail in a couple following posts, but don’t let anyone convince you a wood stove cannot be installed in a Passive House. It’s simply not true, and the details to get it accomplished are not hard, or sophisticated, by any stretch of the imagination.
