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. It looks like the tipping point has finally been reached , where people now see the sense of it , and are adjusting there renovation budgets to achieve a properly insulated home...................... 3 cheers for the building industry , well done.

Have you ever used R19 TStuds. Solves the thermal loss problem of traditional wood studs, and they are stronger. Easier to pull wire and run plumbing too.

[@Terminalbeats]

Those candies were my favorite part

[@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.

[@TheGuyThatEveryoneIgnores]

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

[@heyyou6426]

Explained beautifully

[@mikegirard4388]

Modern developers didn’t forget about overhangs and eaves. It’s just cheaper to build a house with the smallest roof area and soffit possible. Shingles aren’t free. Overhangs were common prior to Prairie Style. My 1925 central hall foursquare had 40” eaves. My current 1905 home has about 24” eaves.

[@WWHVAC]

Nice demonstration and design!

[@MyGoogleYoutube]

Contractors that I would trust to build a home to this standard and with this much technology. Zero.

[@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”.

[@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....

[@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.

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.

[@hillbillyjer]

I guess plywood works but I was taught to nail in a flat stud for drywall backing, just turn it sideways and you have 3/4” backing all the way up.

The power utility neither needs nor wants your residential solar power, but by law they are forced to credit you for it.

[@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).

[@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.

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.

Given that, they are not going to marginalize their own media channels by making all of the content available here. They have no control over the KZbin platform, so they have no assurance that KZbin will always be a viable platform for their content; it may not be right now for that matter. They certainly do have control over their own website (not geocities) and plenty of influence on how they are treated with PBS.

On the exterior, you put a zip system to cover the sheetboard connections and then put ridgid foam board.

3:32 What other types of materials are out there that are 10 times stronger than wood but have 50 times the R-Value while being 10 times smaller than conventional 2X4's? If you could do that and it being much cheaper in price to produce and put in buildings from houses to skyscrapers this would be so nice. 17:38 What do you do if the temperature is below "0"? This is why it would be nice if we could find a heating and cooling device that could replace unites like this and furnaces and air conditioners etc? If they could design a unite that could heat or cool in any kind of condition even if it is a dry or humid, wet or dry areas. If the unite was no bigger than 3 in X 14 in X 30 in. It would be nice if the entire system for heating and cooling could use this thin flexible tubing and there would be not those big ugly registers that people can see. This would allow for different rooms to he heated and cooled individually at the same time and different areas of the room to be heated and cooled the same way. Instead of the big registers being so wasteful there would be very small holes that would be hard to see but spread around the room equally. For example you are trying to keep a room cool but if you stand in front of the window it will be warmer than if you stood across the room away from the window. The holes near the window would put out cooler air while the areas away from the window will put out less cool air and the fact that conventional heating and cooling systems can be heard because you have a grate amount of air pumped through the big ugly register. With hundred of small holes spread through out the room less air has to be put out which the room will stay much quieter. The returns would be small like this and at the same time if there was an earthquake you wouldn't have heavy duct work crashing down and breaking. The unite could be designed small like mentioned above so it would fit between studs in a closet and not take up as much room as out of date systems do and it this system was designed to use less than 2 Volts of power for heating and cooling even at the same time this would be good.. As well if one of these unites could heat and cool a space that was no bigger than 550,000 Square Feet in size. If you could get this same system to heat and cool your water on demand without a water tank, you would have it made.

[@nathanaelsnyder372]

Informative comment. variability in design is very difficult. At least difficult to do economically. Thinking of HVAC we have two main internal loads Sensible and Latent. Although it is not necessary to use one specific size duct or pipe it is most economical. Refer to your frictional loss and pressure loss calculations. As well as boundary layers and viscosity of fluids. Perfection is what engineers and designers strive for, but we tend to overlook the feasibility, design, maintenance, production costs and the supporting devices. There are some softwares open to public download to do flow modeling, but we must add the sensing equipment to make the design work as intended. This idea, if done properly might cost more than the house and save a few dollars a year. Takeaway--- Air requirements for residential structures and pressure loss calculations to backwards calculate the size of the pump needed to move the fluid.

[@napoleonsmith7793]

you would be better off offsetting 2x4s instead of 24 inch centers with 2x6s. every 12 inches put a 2x4 in a 2x6 frame with one on one wall, the next one at 12 inches on the other wall. no contact from inside to outside and you still get a 24 inch stud bay to nail to. just the outter frame goes from outside to inside. just my opinion.

16:37 "The whole house is being monitored, and that's a great thing." ...Is it though?

Not this way, watch the build show here on youtube and they use truly the state of the art products.

Monitoring of a house is awesome unless you're a paranoid person who thinks big government is coming to get you. If that is you, not judgement, but people some people have this grandiose mentality like they're so special that there's an entire department in the government dedicated to get just you. Those paranoid people end up dying ranting and raving about the same stuff that never comes to pass. I mean, how many videos and e-mails mentioned martial law and Obama and did anything happen? Spoiler, no nothing happened.
