    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.”

    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.

I have been in very expensive homes around here that still rely on this practice and it needs to be put on blast.

      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.

  • @mitchellmedeiros5654
    @mitchellmedeiros5654 Місяць тому +1

    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.

  • @tealkerberus748

    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 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

    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.
    His wife considered herself a designer and thier houses always sat a long time because of it. Every year they would do a parade of homes house and it would be 6 months later when it would sell when most of the others were sold before the show.
