This Old House | HVAC of the Future (S40 E3) | FULL EPISODE

[@thebl4ckd0g]

I've been watching This Old House since I was a kid, and they never fail to disappoint in the amount of knowledge and information they provide every episode. This is why the show has lasted this long IMHO, bc they explain things as they go - and I love that!

[@andyjame9774]

the author does like to from scratch, shaping and trimming wood from large blocks into fine finished products. kzbin.infoUgkxD-QRFQz730FJEh4f9BYSf-nkIMIC9hL_ as another reviewer mentioned, most projects require a lot of high-dollar equipment that most of us dont have the room or budget for. But, knowing how to do these things, even if we wont be able to practice the full stack project, is still great.

When I was going through HVAC school, I would watch TOH videos to see Rich explain and demonstrate a concept I was having trouble with, and I would understand so much better. Now that I’m in building sciences and I’m getting into energy modeling, I use this presentation as a teaching tool to help new techs, and I still watch it again for refreshers.

it's just great seeing how this building practice has matured , and the insulation/moisture barrier products being used in some builds now , this approach revolutionary.

Explained beautifully

[@kylekyle8471]

On that outside corner, instead of waiting time and fasteners, why didn't you just put a 2×6 stud, 90 degrees to the corner stud? Gives you a full length nailer and beefs up the corner. Also saves time as it's installed during framing.

[@williamskrainski8407]

I reframed a kitchen floor back about 20 years ago and had a plumber come in behind me and box notch my new framing.....it took three guys to hold me while he made his get away....

[@yssubed2]

Sure the wider spaced studs will reduce thermal bridging but you still have the stripes. What they should have talked about was eliminating the thermal bridging by using foil backed foam panels to sheath the entire outside of the house before applying the regular exterior sheathing. Even 1” will make a dramatic difference. Better is 1.5” or 2”. You add 7-14 R value and eliminate the bridging. This is pretty standard in custom building in Canada now.

[@itech301]

that's part of the modern code in the US as well. They neglected to mention it here, but I'm sure they will when they install the wrb.

[@MustPassTruck]

I like the external blanket idea from Matt Risinger's channel or a similar system by Roxul better. Also like the idea of essentially having 2 walls separated by insulation.

[@TheGuyThatEveryoneIgnores]

A double wall would have been more energy efficient as thermal bridging would be mostly eliminated (and the wall could be arbitrarily thick).

[@Nill757]

High efficiency insulation and air barriers -> yes. Net zero energy, making your own power at five times the cost of the 24/7 utility power, which is still required, even after building an entire addition structure just for solar? No. It’s a racket. Might as well attempt net zero food, clothing, transportation.

If the government passed a law paying you for the majority cost of a cow and a milking machine, along with a guaranteed retail price for your cow's excess milk, then you might imagine getting a cow in the backyard was a great way to save money too. The power utility neither needs nor wants your residential solar power, but by law they are forced to credit you for it. They can make clean power more cheaply with less resources than rooftop solar ever will.

[@Lewis.Alcindor]

3:10 The stud insulation value of R5 would translate to a U-Value of .20, which is fairly decent for a closed window. A better analogy to an open window would be concrete or metal studs (which would be effectively R0-R1). In terms of thermal bridging, wood is fairly benign compared to metal, concrete, or masonry.

24” on center framing came from building habitat for humanity homes in the 1970’s. Needed to lower lumber costs and found better insulation as a happy accident. Building better does not need to be expensive...being pretty is expensive and that makes for good TV.

[@SkylerKing]

It occurs to me that switching to 2x6 rather than 2x4 has the very obvious drawback of reducing internal floor space. It also doesn’t have the same strength characteristics as 2x4, despite what this guy is saying. He’s likely only thinking or referring to the compressive load that the wall can handle (vertically). It won’t have the same lateral strength, though, or the same perpendicular rigidity for the walls. However, placing studs 24” on center rather than 16” on center does mean that less material must be laid out and framed, less time is needed for said framing, etc, which means money is saved on both materials and man-hours while still being able to charge the customer the same amount (if not more, since it’s a “new and modern” design). I suspect that may be the biggest motivation for this “breaking of convention”.

[@blazeharding574]

For the insulated header, I have seen this as common practice to put the insulation on the interior part of the header, but why not put it on the outside, or sandwich it? Most building science theorists say putting insulation on the exterior side of your building is more important because it keeps the structural part of the wall inside of the thermal layer. In a sense, less expansion and contraction because it has an R14 barrier on the outside instead of putting the wood exposed to the temperature changes without any insulation (or less insulation when coupled with exterior insulation).

[@michaelholliday100]

Why would you not do an exterior insulation to eliminate or give a thermal break?

[@HistoricHomePlans]

It's generally a very good idea. But there are some reasons why it is not the answer for every project. On an addition/renovation you might want to match the original wall thickness, so that both exterior and interior finishes align. Also, when you put insulation outside the exterior wall sheathing it adds a level of complication to waterproofing details around doors and windows that many builders aren't familiar with. Consequently it may take them longer and they will charge more.

[@michaelholliday100]

@@HistoricHomePlans but I thought that you were trying to accomplish a Net Zero house?

[@texgibson6236]

If you build a double wall with a two inch air space between the walls with insulation in both walls. It how they build older builds in German. It is very warm on the inside. How open up one these walls in winter time. It was cold on the outside and between the walls. But build was warm and with single windowers.

[@drewp503]

net zero isnt as much about cost savings it's about comfort...a normal house has a ducted system that basically runs heat or a/c steady everyday, blowing recycled crappy air around all the time...a modern house uses geo thermal for cooling and radiant for heat...add in good insulation and an air tight jackey you will have a pleasant house that's cheap to run

The original panel is probably long gone. The majority of the wiring in there was fairly modern so they probably replaced the panel when that was added. The house was originally all knob and tube and a few pieces still remain because you pretty much do need to do a whole house renovation to completely rid the place of that stuff and this is likely the first time that's ever happened for this house.

[@schlz69]

MAtt Risinger on the Build Show is doing nevel level things compared to this. Instead of the 2x6, go with off set 2x4, which make the wall thicker for more insulation and leave a gap between the 2 two 2x4 for spray foam to get into. On the exterior, you put a zip system to cover the sheetboard connections and then put ridgid foam board. Using 2x6 boards and spaced out farther is obviously better than 2x4 with 16 on center, but this is old news. Nothing new being shown here.

[@wholeNwon]

Great to see tech progress, esp. in HVAC, solar, etc. But whenever I do the math. I almost always return to the KISS rule. A single failure in complex systems, something that must be more likely to occur than in simple systems, will eliminate the cost savings from enhanced energy efficiency. Complex systems also usually require more maintenance as well. Where I live, energy is relatively inexpensive. Often the average human lifespan is too short to justify the increased expense. Perhaps that's not the case in other areas or different parts of the world.

A cold wall surface could lead to condensation which would not be good.

[@robj2704]

I believe it should be "code" that bath fans be on a mechanical timer (about $30) of, say, 0 to 30 minutes so the chance of a bath fan being left on is eliminated. Many bath fan users leave the bath fan on for a bit longer to give it time to move the humid air out, but can forget about it and not return to the bathroom to turn it off. At 70CFM, it doesn't take long for a fan to suck the conditioned air out of the house, whether summer or winter. Regardless of how tight a house is built, air is going to come in somewhere to replace the air being sucked out. That outside air is not what you want invading your home since it has to be conditioned by the climate control system of the house. I can appreciate the host's effort to counter this problem, but most people just can't afford a system like being suggested in the video. Range exhaust fans just aren't used for an extended period, but they should be able to function as long as the food preparer needs. And, the food preparer is typically in the kitchen to turn the fan off when it's no longer needed.

[@bloodcarver913]

Wouldn't it be cheaper to demo the old house totally and build from scratch?

[@JanGokor]

No because of bullshit government regulations. If you build from the ground up it will cost way more that keeping the existing walls. Here in Los Angeles they will MAKE you install solar, install a rain collection system, MAKE you install a certain amount of trees per square ft of you lot size. Plus because of the earthquakes we have you have to hire a siesmolgist to work with the architect to design a "safer home" but if you keep just 20% of the existing home you don't need to do any of that
