Net Zero House - 4 Tips for Design & Construction

[epicdeuce]

Another fantastic video! You're giving us lots of new ideas to put into our upcoming home build, thanks Matt!

You need a part two video about this home, inquisitive minds wanna know more.

Another great video Matt, as always! I've been following your videos for over 2 years now. I was about to ask the same thing about the TPO roof until I saw that you answered Joe Large and that's exactly the same kind of roof we have on the Riverwalk Mall in New Orleans. I operate and maintain the 2200 ton HVAC system for the building along with the building's M.E.P. It's a vinyl roofing membrane with a soft foam insulation underneath.

This is an outstanding house, it's light-years ahead of my newly remodeled 1904-built shotgun-double house that I just bought. I don't know if you're familiar with New Orleans architecture but it's basically a rectangular shaped house with no hallways. You literally have to walk through 1 or 2 bedrooms (depending on the size of the house) to get to the kitchen and den in the back.

I’m hoping to see a video on home building in a hot and dry climate.

U r spot on about the glass. Even with code requirements there’s the big culprit on efficiency. I see this as the new big wtf to do. I heard there’s a r-11 window made in Colorado n I think it needs to be better. Up in the gwn we get dam cold n windy 6-8 months sometimes n u wouldn’t believe the crap that’s going on.

Net Zero and Passive House designs are the future.
If you can save energy you save money on utilities.
Air sealing is under appreciated. Blower door testing is a must.

Matt Great video, Awesome work. Love the design and net zero.

Awesome video!! Great tips, I guess we should get rid of our 11' x 6' single pane window on our 1941's mid century modern house in Vermont.. LOL, As we want to do a deep energy retrofit on it..

Great video, Matt! Wish I could get you to build a house for me!

Is this a net zero house on paper (i.e. calculated), or do you have a year of more of actual data on the performance of the house?

[Chrissers]

Viewers, keep in mind a heat pump water heater, used indoors, works well in a climate that is dominated by the need for air cooling. In my climate (Pacific Northwest) we are heating our homes 7 to 8 months of the year, and so you wouldn't want to use your indoor heat for your indoor heat pump water heater. It could possibly work well in the garage however, except for on the cold days.

perpetual motion and net-zero homes have a great deal in common...

Matt i noticed there is room for more solar. Is it safe to assume that if you utilized more solar, you'd be able to add more glass? Was doing that cost prohibitive on this project?

[MirabelaTicu]

Awesome video, as always!Which company did the solar?

[Merdi]

heat pump water heater sounds like a great idea. how does in the winter though? doubt you'd want cool air getting dumped on you.

[Z-add]

Why do you need hot water all year around in texas? You only need it during winter and you don't want cold air in your house. Please explain the reasoning behind it.

Nice video, I was just wondering about the rigid foam. You mentioned its use in several locations. Aren't there companies that sell rigid foam that off-gases over a period of time which results in reduced efficiency? How can I be sure that the rigid foam will continue to keep it's R-value over the course of 10-20 years. Or is there a point at which you can't expect it to remain insulating?

[michaelleroi]

Can you recommend builders in Missouri? We want to go to the Central to South area

[CRsolar]

call CRsolar in Pflugerville if your looking for a top solar installer in the Austin area. more affordable with top of the line panels and components

[JoeLarge]

Great job Matt. You mentioned tpo roof? Not sure what that is. So with the extras over standard, and solar. Any idea of roi?
