This is a 5 star video. I'm not a builder, I watch because I believe in building things well and the inventiveness of high performance building. The real future of building is solutions like this that are lower cost and realistic but also plug into the systems and teams that build houses today. We need to continue innovating and bringing the details of high performance builds to every day builds.
I’d love to see some retrofits. I’ve gotten into the home air quality and enclosure performance profession in the last few years and TONS of people need ventilation/dehumidifier retrofits!
Who makes this duct/supply grille system? EDIT: Found it. “A RHEIA system is designed to supply the required airflow to each room of a home. A typical air distribution duct run delivers 35-45 CFM of air. Duct runs are added to a room until the required airflow is met. This airflow can be met with a supply duct pressure drop of 0.3-0.4 in wc, and a total external pressure of 0.7-0.8 in wc.”
Matt, great video alway thought it was crazy that all my AC equipment is in the attic that reaches a very high temperature during the summers here in North Texas.. Thanks for all the great content..
I also live in Colorado. We built our House in Southern Colorado with ICF in 2006. Full Basement with the added advantage with ICF that it is already insulated. Put in 9 foot ceilings to allow regular duct work to run in the basement ceilings including plans for future bedrooms and bathrooms. So yes all my duct runs are in conditioned space. I didn't know I was so ahead of the curve! Had the perimeter of the basement partially finished out with drywall and electrical outlets and temporary ceiling lights. I am just amazed what they are charging for new houses now. 450K/1800 SF = $250.00 a Square Foot Finished. Will be finishing off the Basement this year for total of 4200 SF living space. Unless you live in a wet climate or have a high water table a basement still makes economic sense Especially with something like ICF. Our Basement temperature is 72 degrees year round. I see a lot of the builder's here in our area are also going to Slab construction as well, to cut costs and mostly single story. He has a good idea, but our house has a heat pump, with a Steffes Thermal storage system for back up in the winter. Which I will be upgrading to a cold climate heat pump version this fall to reduce the need for the thermal storage unit. Has a Air Exchange unit. Had a Solar Hot water system put in for probably the additional cost of his duct work with a 120 Gallon exchange tank. Will heat all 120 gallons to 150-160 degrees on most days from late spring through early fall. Do like the idea of the heat pump water heater though. Thanks for a thought provoking video.
One topic I'd like to see discussed on your channel is the use of unlined joist bays and wall cavities as cold air returns. It's very prevalent in the Midwest. Every HVAC contractor just says "well it will get caught by the filter", which is obviously absurd. I have been in very expensive homes around here that still rely on this practice and it needs to be put on blast.
So basically run your ducts through the attic still. Run them closer together Then frame around them in attic . Then spray foam the heck out of the enclosure. Put vents from inside the in ceiling to make ducts conditioned. And yeah air handler too or put it inside house closet.
I don't see why they're running individual ducts instead of a trunk and branch system and insulating it the same way. Seems like there's a lot more wasted space, and flow restriction, with all those flex ducts
Zip-R would be a waste of money since he’s insulating above the ceiling and then up and over the inverted soffits. I like the way you’re thinking though-looking for ways to innovate 😊.
this is a very cool idea. less work for the system to do with it being inside the conditioned space. seem like an alternative set up if there is no attic space to run the ducting
I would still recommend sealing bottom plate to keep pest out of the home in Georgia. Just Wondering what the blower door test after a few years of the home settling
I’m remodeling my 1959 house and found out it has exterior insulation foam. Brick outside, foam, then a type of gypsum nailed to the studs. Come up to Abilene to check it out.
Why not just build the house af oot and a half taller, Drywall then install another ceiling, a foot and a half down And have unlimited space to run all your ductwork. I built a commercial building like that, and it was super efficient.
That would be a lot more expensive than what Charlie is doing with the inverted soffits. The ripple effect of that extra foot and a half in a house would be significant as opposed to commercial construction where the typical means and methods of construction allow the incorporation of a ceiling chase much more economically. In fact, what you describe is standard practice in commercial construction.
This makes so much sense! I have a home built in the late 50's. I have inverter window units. My old house stays good and cool when in the mid 90's outside.
This is a solution needed exclusively for bungalows on a slab. With a 2 story you could just run everything between floors using an open web floor truss. Or an insulated crawlspace under a traditional bungalow.
My next house will be over a crawlspace, but for effective ventilation we need vertical air movement. That means either the air enters the room through the ceiling and leaves near the floor, or vice versa - but if it's entering and leaving at the same height, you're trusting the 'throw' of your vent covers to do all the mixing for you.
@@supeerchoonThe majority are not and as for where else: basement, walls, soffits, reverse soffits, plenum truss, floor trusses, etc. or ductless or just convert to a conditioned attic or have them in a semi-conditioned/conditioned encapsulated crawlspace.
That aerosolised caulk is very similar to how we seal cracks in earthen farm dams - add a compound to the water that is carried to wherever the water is leaking out, and anywhere the droplets of compound touch each other they bond to seal across the cracks. It won't seal big holes, but it's great for tiny leaks. Still, I'd like to see some safety data before releasing something like that into air that people are going to breathe. What happens when the micro-droplets of aerosolised caulk bond together inside someone's lungs?
i was thinking the same thing, like make a floor truss with a traditional truss on top; like you put in a floor truss to top your ceilings, deck that for air sealing, and then put all of your roof trusses on and insulate from there; am i missing something there? maybe the added cost of the additional floors trusses and the total decking, but it would be super easy to implement if you didn't have a BS expert for custom trusses;
Quite a few things to correct. Ducts are within the insulated envelope, not within the conditioned space. Definitely not the most energy efficient way to run duct, much higher pressure drop and will use more fan energy than traditional ductwork. Seems like a good application for a retrofit, but in this application you have plenty of room for hard ducted mains. You typically want to limit the extent of flex duct since it has a higher pressure drop. Being forced to use those cheap grilles is not great. Mechanical room within insulated envelope is nice, just need to confirm your heat gain in that space, depending on equipment.
So you mean like we do it in Canada for, well, forever? Aerobarrier is great, for new builds. I priced it out for a house you live in, cost is very high due to all the work involved covering everything, or moving stuff out into a storage unit
Putting the furnace/air handler/evap coil in an HVAC closet in the conditioned seems like a good idea. But I have to wonder if It'smore cost effective to install radiant barrier to get attic temps lower and use conventional R8 flex ducts cover with 2" closed cell spray foam.
I am thinking it'd be much better to insulate exterior of roof, which would allow simpler (rigid) distribution. You could elevate the handler horizontally with drop ceiling and make everything more serviceable. Don't really get the erv being in the garage. Bottom line is that the mechanical room is too small, and ducting is overly complicated and uninsulated, which on its own wouldn't pass code in some jurisdictions
would it be possible to achieve a similar result by raising the roof 8 or 12 inches and doing kind of a drop ceiling? that seems like less back-and-forth between trades and engineers, and a cheaper roof truss system
The ripple effects from such an approach in home construction would be significant. Looks like Charlie has it pretty dialed in to be as cost-effective as possible.
I mean they were having proper Manual J, S, T, D done so presumably they had it all calculated right plus I think he said its will be commissioned to test all of that so it should be correct.
Pretty sure because of the dry air Utah has some of the worse HVAC guy in the nation. They get away with sloppy work and horrible duct work that would cause nightmares in humid areas.
You don’t build a house with the assumption it will be gut in the future. You build it to function well as built. Those chases should make future work easier cuz the insulation won’t be disturbed if you change/ replace something. Everything is protected.
@@rpvitiello Matt specifically talks often about wanting to build houses with ease of future remodeling in mind. The chases may help but it's more likely they will make it more difficult since everything is so custom fit to exactly how it is built today. Not a bad thing, but it's not all roses either.
Puts in a thousand mini ducts through expensive insulated truss troughs and then brings the air back via a couple of main returns going through the hot attic. Okie dokie.
Sometimes the term hot water heater is used to refer to domestic hot water as opposed to water that’s heated for another purpose (e.g. hydronic heating systems). Most of the time it’s just an unnecessary redundancy, however. Okay, I’m headed over to the ATM machine to get some cash now. Later.
The builder probably came from a multifamily background. MF builders have been utilizing fur-downs in design for this very same reason for decades (albeit without the air sealing component). How is Charlie insulating the inverted soffit/ pop-up chase? The trusses are framed on the 1 1/2” and OSB is fastened to that. How do you friction fit FG Batt to a 1 1/2” hot wall? Attic Blow won’t stay at depth on top of the inverted soffit without an insulation dam.
Not a fan of this method. Don't like the non continuous air barrier. Don't like the complexity. Don't like relying on spray foam for the OSB. Don't like like the reliance on the aero spray sealant. Don't like the hidden flex ducts. Don't like the super complex trusses. Don't like all the penetrations I saw either. Would rather have a flat, taped OSB ceiling with a firred down service cavity. I think it would be cheaper and simpler.
13:55 Heat pump water heater 3 inches from a heat pump air handler. Man, seems like it would be so easy to run another set of lines from the outside condenser to the water heater tank and not have to have all of the additional complexity of another heat pump WITH ITS EVAP & CONDENSING UNIT in the closet with the air handler.
@@noedengineer Yep. Did pretty well in Thermo I & II. That’s not what I was referring to. It’s the complexity of repeating whole the exact machine that drives the HVAC unit.
The heat pump water heater is an all in one package unit. When installed in mechanical closet, there is an exhaust to outside and fresh air intake piped to it.
Because he’s already insulating at the ceiling plane and then up and over the inverted soffits. Zip-R would be redundant. I like the way you’re thinking though.
Ok, Mat, I live in Wisconsin, here's kinda a stupid question or maybe just a flipping Ridiculous question, so after see this and having the HVAC not up in the attic space, on a conventional unit, what if one would install a Mini split in a mechanical room other than having the outside unit outside, whats the set back other than running hot air in that room or maybe hook it up to and exhaust fan to the outside when that fan kicks on, it would be in climate control environment
Completely baffling why Texass builds most houses on slabs. You put in a sealed crawl space you can put all your hvac duct work, plumbing, etc in an easy access temp stable non conditioned space.
Why would they use a single large rigid duct then T off of it for the room returns? If these ducts ever need to be clean, it's going to be a nightmare.
Why are these "credits" and "rebates" scams provided to builders or installers? It is the occupant who is ultimately paying the for the equipment and the labor.
talk about burying the lede... just casually mentioned that doing it this way makes the trusses way more expensive. Yes it sucks to have ducts going through a hot attic, but insulated ducting exists. It's way cheaper to put in super-insulated ducts than it is to get custom trusses with expensive extra webbing.
How much do you have to pay for a video like this. I know this builder and he isn't a good builder by any stretch of the imagination. He considers a signed contract only valid if it benefits him. He's a typical rich kid that took over his daddies company and operates on his families money to build houses and develope land.

If it’s like the Zhender duct system, it’s much more rigid than flex duct.

HP water heater helps throwing off cool air in the mechanical room. Looks like a service nightmare though.
So... extra cost in trusses and instalation of the plywood in inverted soffit... or just monopoly frame it? Cost comparison would be nice.

Everything is Colorado is going over to electric...... EVERYTHING.
And Oregon and Washington and California and Hawaii and ….
Is the load calculation done with open doors or closed. Don’t doors affect the air flow and then you don’t hit the numbers you are targeting
Would it be possible to retrofit this into an existing truss system?
would it be possible to achieve a similar result by raising the roof 8 or 12 inches and doing kind of a drop ceiling? that seems like less back-and-forth between trades and engineers, and a cheaper roof truss system

@MichaelJ674 Correct. However, if you were planning on doing 9-10 ft ceilings this install would be more expensive and less efficient I think.
What's the model on that heat pump? I'm having a hard time finding anything that doesn't require 750 cubic feet or more.
So I'm wondering if the HVAC guy also installed the ducting?
Yes. Monarch HVAC also did the installation.
Nice
Seems like a lot of pressure drop since the main seems far away.
That was my thought also. How much flow could you get through a small duct over that long a distance.
I mean they were having proper Manual J, S, T, D done so presumably they had it all calculated right plus I think he said its will be commissioned to test all of that so it should be correct.
