Chris from Binghamton (soon to be GREENE, NY)writes:Greetings FHB Crew, I just wanted to take a minute and update you all. A couple weeks ago my wife and I had a meeting with our builder and he shared some numbers that made my eyes pop out of my head. We spent a couple weeks trying to make the math work. In the end, we couldn’t do it. So we have abandoned our plans to build. It was an excruciating decision, but in the long term, it makes much more financial sense.
In total, the failed experiment will cost us money, but I have to say that it wasn’t a complete waste. Engaging in the planning process has changed the way I view and understand homes on a number of different levels. Understanding the home as a system, acknowledging the carbon embodied in materials and not just emissions, recognizing the difference between temperature and comfort, just to name a few. So, I know my experience as a homeowner will be much different moving forward after having gone through this effort.
Speaking of being a homeowner, after making the final decision to give up on home-building, I turned, as many do, to doom scrolling on Zillow. I came across这个性质… and decided to get back on the proverbial horse. My wife and I viewed the house this morning, put in an offer and have signed a contract. Although we won’t be sticking with the eternal blue theme for long, the home has many of the qualities we were looking to include in our designed home. We think it is the embodiment of “pretty good” for us.
Built in 2018 on a 2.53-acre double lot, the home has a 42,000 btu 5 zone Mitsubishi mini-split heat pump system. Awesome Before I put in my bid, I ran the numbers through the energy model spreadsheet Ian helped me with and the system seems to be sized correctly. Thanks Ian! The house runs off municipal electricity which currently charges a measly 7.5 cents per kilowatt hour. Sweet. The blower door test in 2019 showed 1.34 air changes/hour. Not so bad. It has mechanical ventilation of some sort, though I need to get up in the attic to check it out to see exactly what kind of unit they have running. I could go on, but I’ll stop myself. Just wanted to share a twist in our journey and also thank the entire collective crew, past and present, of the FHB podcast. I’ve learned a lot and will continue to do so, all while thoroughly enjoying the various content you all produce.
小心,
Chris

Dack writes:Hello podcast guys and gal: Just listened to第443集. Ian, could your company’s move towards panelization be accomplished with … panels? I’m not in the industry but SIPs seem like an obvious solution, veering towards no-brainer. Mark LaLiberte and Justin Wilson (the Construction Instruction guys) are both big fans, and Lstiburek wrote a book about them. That’s good enough for me.
I’m working on a small cottage project with Minneapolis-based timber framer. It’s only 900 square feet, but the estimate to have a frame cut, erected, enclosed in SIPs, and a 5-man crew to drive from MN to northern WI (and back) and spend 5 days putting it up is $80K. Granted, it’s missing a lot of things, like a foundation, but this seems like an affordable, fast way to get stylish, durable, high R-value shelter.
In fact, I see an opportunity here:
* automate the labor-intensive timber framing piece (the Germans, naturally:https://www.homag.com/)
* enclose in SIPs
* offer consumers a range of combinable modules (likehttps://www.thebackcountryhutcompany.com/but practical)
* PV-ready roofs for net zero
Let’s save the planet and solve the housing shortage, in style. Who’s with me?

Kenneth from YouTube writes:In第449集杰西很好奇门浴。如何about a contemporary barn door? Minimal trim. Easier (?) to create a custom sized barn door. The only drawback is the door and door hardware would need to extend off the wall to match the depth of the decorative column.

Question 1: Is there a DIY budget friendly way to monitor humidity in wall assemblies?
Brian writes:Wall Humidity Monitoring?We are finishing a portion of our basement and I am curious if you or anyone on the show/audience has found a DIY/homeowner budget friendly way to monitor humidity in wall assemblies? I know consumer hygrometers aren’t super well calibrated, but after finding an old terrarium hygrometer I had laying around I was wondering if this would help discover if there is any dramatic changes inside wall assemblies (specifically the laundry room). My DIY thought was basically to just drill a hole in the drywall and snake the probe through and leave it in the wall in a place I would see when doing laundry, but I didn’t want to reinvent the wheel if there is a better way to do this without doubling the cost of a wall.
Dryer Vent Specifically:The dryer vent is going to be buried in the wall and I believe I have covered my bases with a short run (12 ft or so) all seams screwed, taped and clamped and then using a full 2×6 wall so the vent isn’t being compressed to fit through 4″ cavities, but I am still terrified of the disasters I have seen with these vents causing issues in walls.
Anyway, thanks again for all that you guys do with the show, it’s been a huge source of help and motivation to keep getting my ’56 cape back into fighting shape after the previous owner let things go for about a decade.

Question 2: Can I use pine paneling on the walls of my barn with no drywall or vapor barrier behind it?
Alex writes:Hello Podcast crew, I’m wondering if you guys would approve of my using pine paneling on the walls of my barn, with no drywall or other vapor/air/whatever barrier behind it.
这是情况:它是西部马萨诸塞州的130年历史的气球框架结构。当我购买时,它崩溃了,我逐渐修复了框架,重新侧面,添加的门和窗户,并且基本上是转动的it into a workshop/cabin/teenagers’ hangout. Building code, um, doesn’t really apply.
现在,我只有在那里有一个木炉时才加热它。我逐渐将其绝缘,一次是一堵墙,带有鹅卵石刚性泡沫或矿物质羊毛或我觉得便宜的东西。I have then found myself covering it with tongue-and-groove pine, or in the case of my kids’ space upstairs, rough sawn one-by pine, and all the while in the back of my head hearing segments from past episodes of the podcast where you guys talk about water problems in homes with pine paneling, from the moist, warm interior air seeping through the gaps in the boards and condensing on cold framing. Is this something I really have to worry about in this semi-inhabited structure? Though I don’t heat it full time, I can imagine someday having some sort of heat source that keeps it at 60 degrees or so. There will never be any running water or significant cooking going on here, and it will never be inhabited full time. What do you think? Is there some sort of easy barrier I should be using behind the pine?
Question 3: Why does my sewage pump cause the toilets and sinks to gurgle throughout parts of my house?
Perry in Duluth, MN writes:我有一个污水泵,可以从我们的地下洗衣机,洗衣水槽和浴室排出我们的化粪池。停止抽水后,厕所和沉没在整个房屋中。我们的主楼层浴室或水槽不会发生这种毛刺,这些浴室将重力进食给我们的化粪池。这是一个发泄问题吗?
Thanks.

Question 4:如何should I insulate the interior side of a roof without creating an ill performing or risky assembly in terms of moisture?
Hans writes:Good afternoon Fine Homebuilding crew. I have been a listener since I bought my fixer-upper house 3 years ago when I stumbled upon the podcast while trying to figure out how to fix the ice damming problem we were having. Little did I know that the discovery of Fine Homebuilding and subsequently Green Building Advisor would take me down a never-ending path of fixing my house, not just for energy efficiency but structurally as well.
My house is an early 1900s small cape cod in zone 6 in central Wisconsin, that has been added onto a few times over the years. When we first moved in, it was very poorly insulated and air sealed (think gable vents for the knee walls with no insulation in the floor) with asbestos shingle siding that was falling off in places. What we thought would be small changes on our way to quickly reselling the place, has turned into fully re-framing and re-sheathing the house due to rot and deciding to go all in and do a chain saw retrofit and full exterior insulation. All while living in the house while we do the work. See attached photos for some of the extensive work.
Onto my question. This question isn’t going to have the typical answer you usually give to these types of roof insulation questions (exterior insulation) as I have already gone ahead with that part of the project. Rather I am looking for some insight on how to best insulate on the interior side of the roof without creating an ill performing or risky assembly in terms of moisture.
我重置屋顶和添加屋顶,1和2 gable dormers to the house with the assembly structure as follows (general assembly cutaway is shown in attachment), beefing up the old spliced 2×4 rafters to 2x12s, Grace ice and water over the old board sheathing as an air barrier wrapped down onto the walls, 2 layers of 2″ polyiso rigid insulation, 2x material for creating an air gap and for the applied overhangs and then a second roof deck with shingles as the roof covering. A profile of this assembly is attached along with a few other photos of the work. To address some previous podcast discussions on finding people to do this type of work, I didn’t have too much trouble finding a contractor to do the exterior insulation, as I am rather ambitious (aka cheap) and am doing all of the work myself with the help of family and friends.
我的问题是基于阅读有关绿色建筑顾问的一些文章,内容涉及将刚性绝缘和蓬松的绝缘材料结合在一起,并建造有效的大教堂天花板。困境,两层polyiso将使我大致为R25,这大约是我的气候区域的最小值,与蓬松的绝缘材料相比,绝缘的约50%。这将导致约6.5英寸的蓬松绝缘材料。由于我使用的是2×12框架,因此我只会填充1/2的the,据我所知,这不会使巴特绝缘材料有效。如果改变任何建议,我将使用晶圆灯,并有可能在after湾中运行一些管道工作。
因此,总的来说,问题是,我应该如何详细说明内部绝缘材料以不使我的组装风险冒险?
My current thought is to partially fill the bay with insulation and then use a smart membrane against the insulation and taped to the rafters to add an interior air barrier against the insulation. And to answer another question you may have been thinking as you read all of this, yes, I am an engineer.
提前感谢你的答案(s)你可以提供e as well as for inspiring myself as well as others to take on these kinds of house projects in an effort to make our homes better than they were.
