Too complicated, I told you so Matt! When you first described you house plans I said you were getting too complicated and should focus more on passive heating and cooling and reducing your power consumption. Instead you went with very expensive high tech systems that YOU will not be able to do maintenance on and will have constant failure issues to deal with. I built my super insulated off grid cabin myself for cash and my solar power is only 1.4Kw. I was able to retire at 49 from the savings and I can do all the maintenance to keep my system running for the rest of my life. No house payments, no utility bills and freedom!

I've learned I have to think outside of everyone else's box, which means I have to communicate to businesses, institutions and governments outside their forms. I have to learn what the rules for building, zoning, manufacture, plumbing, electrical, HVAC are, and why those rules are in place, often when the people enforcing the rules don't know them. What I thought would be tech turned out to be civics. And in delay due to red tape. Especially, when the original builder did things outside the box, too, like laying all the electrical and telecommunications diagonally across the yard, making it impossible to do installations without excavating at great expense what they laid down without cost or thought for the future.

I suggest from my own experience of having a house built to allow a lot of ventilation [ even in winter ] for the first 12 months despite energy loss. The building materials,sealers, paints, varnishes out gas an unhealthy amount.I did not do that and my wife got very sick over the first few months [ she works at home so she was home 24/7 ]. Sort of a chronic fatigue syndrome that disappeared in spring when windows were opened.

Interesting. I'm also highly sensitive/aware of chemical off-gassing - so would have tried to find alternative (ie. less/no VOC) products ahead of time. But as this is obviously time consuming (and not typically a realistic thought with most sub-contractors), wouldn't an HRV (Heat Ventilation Recovery) system exchange the interior air enough? I was under the impression that any airtight homes require HRV's to constantly maintain fresh interior air. Thoughts?

I took a very different approach to my "new" home. Five years ago I moved into my 60-year-old home in the mountains of central Mexico. The house is all masonry construction with 14" thick ceilings and 8" thick walls. The climate here is so temperate that most homes do not have HVAC systems other than opening or closing windows as needed. Electricity can be very expensive, even by US standards, and can be a hardship for local people on Mexican incomes. When we moved in, the electrical system consisted of four circuit breakers and ungrounded outlets, perfectly acceptable for 1950's construction. High on the list was to replace all the wiring and outlets and install a 20-breaker electric panel. For the first six months I kept close track of electrical usage with the idea of adding solar panels. Knowing in advance what my electric consumption was, I spec'd out the system to generate on a year-round average about 4 kWh per day more than I consumed. What I missed was the overhead to run the inverters and normal system losses between my panels and the electric meter, so I only ended up with a 2 kWh per day year-round average surplus. It's enough. Where my approach differs from yours is that I went for a brute-force energy system rather than trying to make a 60-year-old house energy efficient. I have enough solar panels that *_I don't care about efficiency._* My electric bills, which would run me more than $4,000 USD per year without the solar panels, comes to $1.33 per month, which is the minimum grid-connection fee. For my $1.33, the provider "stores" my excess production on a 12-month use-it-or-lose it system, 90% of which they get to keep without compensation because I rarely have to dip into the storage. I give them $16 a year plus four or five hundred kWh that I have no use for, and in return have no hassles or worries about my electricity. Two years ago I started polishing my tinfoil hat and decided I wanted some battery storage. I added enough that I am fully off-grid capable short-term, with "short" being defined as one to two years. This is because I specified deep-discharge lead-acid [I hear your gasp of dismay, but hear me out!] batteries instead of lithium-ion. Why? Because they were less than a third the price of Li-Ion and I could see the incredible changes coming with battery technology and knew that in five years I could replace them with new technology for half of what I paid for them and at the same time get twice the storage. As long as I remain grid-tied, they sit on trickle-charge with occasional short discharge when there is a local grid failure. They'll easily last 10 years at that usage level, but if the grid fails long-term then the heavier duty cycle will do them in in just a couple of years. To lessen the load on the batteries in that scenario, some non-essentials (garden lighting, swimming pool pump, one of the electric hot water heaters, limit the A/C, etc.) would be turned off, but other than that life would go on as usual. I saw on your video 13:58 the specifications on your 26 panel system, and at first thought "That's about the same as mine, but I'm generating 40% more power", then realized that with the exception of the three month rainy season (June-July-August) I am living in a high-desert climate with cloudless skies at 5,000 feet elevation day after day for the rest of the year. Insolation counts for a lot!😀 Anyway, that's my system, and it was one of the best financial decisions I ever made, coming in #2 after the decision to move to Mexico in my retirement.

Vapor barrier sealed on the inside and ceiling then normal sheet rock taped and mudded and a coat of paint to keep the tape from peeling. Then the inside wall is just 2x3 standard framing since it’s just there to run electrical and such. The dropped ceiling is custom made floor trusses 16” high that hang from the building trusses under the sheet rock. From there it’s just normal construction. There is only 1 penetration through the ceiling for the sewer stack and four in the wall, one for the erv, two bathroom fans, and conduit for all the outside electrical. 2500 sq ft and my most expensive electric bill so far is $120 so I’m super happy.

If you include a service layer in your ceiling below your vapor barrier, the extra money in 2×4 will be saved tenfold in envelope management and penetrations.

I wasn’t quite expecting the issue you ran into! I had commented about modular home electrical being tricky awhile back, but this video was so interesting in what exactly your problems ended up being. You explain things very well here and it’ll definitely help people who are looking into the stuff you’ve done to your house for themselves.

Steps I would take after hearing your experience. 1) Determine where the meter "has to be" prior to house design. If you want all mechanicals on the same side of the house, then that is paramount to that design. 2) Design a larger mechanical room and don't be to tight on the specs. If you want all of it to fit, then make sure it's large enough for all of it to fit. 3) Don't start the build until you have all the specifications down on paper. By holding off the build and getting all the specs down first, issues like the unwillingness of two companies that need to communicate with one another, to communicate in a timely manner, would suggest that one or both of those companies need to be changed out for one's that will communicate with one another in a timely manner. But, if you insist on using those two companies, then waiting for both to get their heads out of their backsides is necessary before beginning the build. Even if you end up waiting an additional 6 months for the build to begin, by waiting, you can iron out all the hiccups and have the adjustments in the plans and the build will go a lot smoother and be more efficient. It's one thing to have to wait on something. But why let someone pressure you into having to hurry up and wait?

@HenryLoenwind

8 ай бұрын

Got points, but I'd add: Design the mechanical room as being split in half by a wall, one side being inside and one outside the envelope. That way, all connections can be routed through that one wall in a low-airflow room. It's much easier to make that one airtight, especially because it doesn't need to be as thick and insulated as other walls with both sides being low-airflow.

Having built two houses from the ground up and remodeled several others, I can tell you that nobody has their design 100% when they start construction and there is a lot of work done by the contractor simply because they've done it many, many times before. In the current market here in the US, if you wait to start construction for 6 months, you likely lose your desired contractors which is a much bigger issue.

This reminds me a little bit of an anecdote about American and Japanese cars versus German cars. I've heard mechanics say that German cars are designed by engineers who don't think about things like How hard it will be to turn a Wrench in the engine compartment, where American and Japanese cars usually allow space for people to work. It seems the same with homes. It's not just the ease of building, but the ease of fixing and servicing the house over time.

grey is a good colour for walls because then you can add any accent colour you want via more temporary objects, or even better for mood you can add colour with lighting. Some funky rgb led lighting is more effective if a room has no colour on the walls, and instead has shades of grey. walls with a colour to them already will change the colour of the light reflecting off them and effect how colour accurate the rgb effects are. Obviously this is more obvious with strong saturated colours. Like my neighbour, we decorated her daughters bedroom for her as a surprise while she wa son holiday. She had a dark purple wall, two lighter purple walls, and a wallpapered wall with a purple galaxy effect on it, and just bare led's taped to the top of the walls. Needless to say no matter how much light you put out of those leds, the room still felt dark and everything had a purple cast to it that made the room feel dark. Now it's got light grey walls, with silver crushed velvet for the curtains to match her bed frame, and i built some proper WLED diffused floor to ceiling light bars and the room feels bright, and clean with there being no colour tone from the walls. but then she can add whatever colour she wants with the leds on a steady colour mode. Or she can put them in a calming slow changing mode. or music reactive mode and the effect is far better with grey walls than the old purple.

Once upon a time, I had grand aspirations to put a lot of tech into my house: home automations, whole-home audio, etc. Then I had the realization that kids don't give much time for that, playing tech support for the family becomes a PIA, and guests don't want to read instruction manuals when they come over to visit, babysit, or watch the house. KISS wins nearly every time, now. The one exception I've given I to is the robotic lawn mower, because the amount of time it saves me is worth any headaches that come along with it.

Having the panel on an inside wall is great! Having it on an inside wall in the garage would have been the best. I think you missed a geo-thermal trick by not having a second 1000 ft of line placed and plumbed to the garage. With just the 100 watts needed to run a fan you could have cooled your garage in the summer and kept your cold weather temp to 45deg F. It could have been inside/outside temp driven. Think of your cars being 45 deg in the winter and no ice and snow stuck to your car.

Fascinating to watch your progress, there are so many ways to build from low tech (my preference) to a home packed with services (your method). I hope you keep us updated as you move in and hopefully get comfortable.

I think the biggest mistake every homeowner makes when building or remodeling a home is that they discover the mistake while the house is still under construction but think "it's too late to fix it" and then they live with it for 20 years until the next renovation. Of course, some things like "I wish I'd made the basement ceilings 9' tall instead of 8'" is something that's impossible to change once the framing has started, but things like "I wish I'd added a window on that wall" or "I should have put the bedroom door over there" can still be fixed. Yes, it will cost more money and take more time, but if you're already spending more money than you've ever done before in your life for something you want (a house), why not spend a tiny bit more and correct your mistake now instead of regretting it for years and years?

I love all this house stuff. My wife and I recently remodeled an old home and a lot of this would have been super helpful to see before then. We're already dreaming of doing a custom build to get the home tech and amenities exactly as we want.

I just installed a secondary hydraulic heating grid in my home, because i wanted cooling from a air source monoblock heat pump. This could have been avoided if, 9 years ago when we were redoing the original hydraulic heating grid from the '70's, I'd sprung for insulated lines. wouldn't even have been that much more expensive. But, no-one in the this country was doing heat pumps at that time, climate change hadn't hit us with 40c summers yet, and cooling was seen as a luxury for glass fronted offices. I did run cat5e to every box in the house, intending to run a CAN network and power over it. never used most of those since the house runs on many ESP''s and zigbee now. Hindsight is 20-20.

Nice house Matt, hope you really enjoy it once all the startup bugs are worked out. Question about that super-clean metal roof install - how did you route all the plumbing vents so you had no vent perforation in your roof and still meet plumbing code? Also is that a ridge vent under the metal ridge cap? Keep up the good information vids - you're definitely helping to blaze the trail forward for all of us hoping to get off of fossil fuels & get more energy self-sufficient.

Hey Matt, would love to see a deeper video on the ERV system! I've always wanted to do something like that for bathroom vents, but the humidity and the number of them seem to make it way harder than it should be. Another video I think would be great to see you do, a little bit down the road, is how do you handle "de-teching" the house when you sell it? Getting it ready for a new owner without totally destroying the value of the home automation. This was a minor sticking point with my last home sale back in the mid 2010s because we had put nest thermometers in for the dual zone heat and the buyers real estate agent wanted us to rip them out and put in standard programmable thermostats because they didn't think we could transfer them to a new owner. I shudder to think about a more complex system like you've built in your old house.

You have to market the house to someone that is interested in buying it. Also find an agent that understands what you are selling. We ran into issues at our house because people buying our house thought it came with stuff that it didn’t come with.

@@worldtrav72Be careful. ERV’s can be a colossal waste of money depending on your goal. We install ERV’s and HRV’s in Michigan and it is hard to justify if you know all the facts and the truth. If your home was built before 2000, don’t even consider it. The initial cost, running cost, maintenance and failure rate will not justify ANY money savings, if that’s why your installing it. If your house NEEDS more/better air exchanges that would be the ONLY reason to install. It’s going to cost you money, and it’s complication you don’t need.

House is looking amazing!

I'd love to hear more about the SPAN Panel integrations / API. I had a SPAN Panel installed on my house during a remodel (along with 15kw of solar and Tesla batteries). It's a pretty cool set up but I'd love to further expand the SPAN with 3rd party integrations.

@@D2O2 One thing you can do when you have a SPAN panel and battery back up is to dynamically change your list of devices that are powered by the batteries during an outage. Without SPAN, this is a one time decision you make at installation. With SPAN you can have your “must have devices” your “nice to have devices” and your “don’t backup devices”. When running off battery for a lengthy period you can easily move things around to extend your battery life. This is possible because those loads are managed by s/w rather than by being hard-wired.

@@PatDoyle I can do that with a standard panel by simply supplying the entire panel with a secondary power source and turning breakers on and off at will. I don't need to be able to do that from Italy once every 5 years. Also, span requires a cloud connection to function, no local control. Hope you can make that connection. Also, since the switching relays are only software controlled, if you lose connection with the SPAN cloud with a circuit commanded off, there is NO physical way to turn it back on. So, SPAN has total control of your panel. Yeah....No thanks! SPAN is a start-up, you have no idea what you are going to get now, or in the future. Best of Luck, hope they leave your circuits on when they shut the lights off at the company as it goes out of business or is bought by someone with other ideas.

I've been in construction for 30 years and still regularly wish I had done things differently. Owning the mistake and drilling through the problem with a level head to solve it in a timely manner is where many tend to go wrong. I can't tell you how many stubborn customers wouldn't take my advice only to have it come back to bite them. The devil is always in the details!! Rember, there's never time to do it right but, there's always time to do it twice! Keep the information flowing!

Thanks for telling us the lesson that we could learned.

I build a net (sub)zero home and moved in last year. I kept it much simpler. I did geothermal about 30yrs ago, but solar is so cheap now that it looks to be a much better value, at least since I've moved south. I do have heat pumps for the house, hot water, dryer, but they are air sourced keep costs much lower, and then put more into solar. So far this CY the system has generated 4.6MWh more than what was used. That is 35% more than needed. I may even add more solar on a pergola, because it makes the pergola and slap a tax deduction, which should bring the cost of that solar to near zero. One think I did different, and I was skeptical at first, was to use foam insulation. That made the entire attic interior space. It counter intuitive to have more conditioned space, but it make work in the attic much easier and less worry of compromising the insulation and house seal.

What to do different next time? Make the utility room much bigger so it isn't so crowded. Mirror-image the house, putting the garage on the right and the living space on the left. And in our PH we used a Climate Master GSHP HVAC that derives the hot water directly. ((Thanks for the PH saga.))

I've always wondered why nobody takes advantage of reserve conduit structures specifically for later alterations and/or additions. I'm also a little curious as to why subterranean conduits and ducts are so often avoided. There seem to be a fair number of cases where two or three simple 1x1' ducts lining the foundation of a home with a few access ports here and there could solve a lot of retrofit/after-thought issues.

Oh yes! Being your own GC is a learning experience for sure. It was foisted upon us unsuspectedly and I don't think I could do it again. On the bright side, I believe we have a more custom finish and more control than we could have otherwise afforded by hiring a GC. But the niggling little details (mistakes like unused, installed tech when the technology changes) will haunt you. Learning that we're not the only ones with this problem, is somewhat consoling. Appreciate the video. Thanks!

When I did my system seven years ago I wanted it as simple as possible. One large dumb inverter. Connected right straight to my load's panel then run everything as normal. And i've been perfectly happy with it for 7 years off the grid now.

​@donaldendsley6199 Exactly. The biggest issues are our single family home culture, combined with zoning laws. Our cities and towns are designed and legislated to have cars and parking. Our culture wants a large home with a white picket fence (or some version. I'm guilty here, as we moved to a very rural area, so we could have a couple acres). The suburban sprawl of the US just doesn't really allow for environmentally friendly layout. Some things can be done to improve it, but the fundamentals, like mass transit just don't work when you have 20,000 people spread over 36 square miles (93 km squared)

The truth is that single family homes are more sustainable than the ultra dense urban high-rise living promoted by pseudo-scientist politicians of a Marxist bent. For overwhelming proof (with transportation) research ET3 Global Alliance- and compare ALL value and sustainability measures with electric trains. Back to population density... it is the problem - not the solution. As proof compair the per square foot construction cost of a 100 story skyscraper to a typical 2 story rural farm house ... compair the tax rates ... compair the air and water quality... the noise and light pollution... the per capita crime... etc. And then understand that virtuall EVERY big city is going broke - AND the cities use political and media power to force those who make better decisions to pay the bulk of the enormous additional costs of density. Even still urban water, sewer, electrical, and waste systems are failing (while rural areas continue to thrive with a smaller percapita footprint).

You don't want a perfectly sealed building for living. The replacement air has to come from somewhere and having to do everything mechanically wastes energy more than allowing air to flow passively in, *and* it can lead to air quality problems if you're trying to save *too* much. We used to make that mistake *a lot* in Finland in the 70s after the oil crisis.

Well Matt… you didn’t invent this one… when we built our forever home (Me: Mechanical Contractor/Building Contractor) 22 years ago in Florida, I performed the mechanical and building automation. Miles of CAD5 back to a central hub. Multi-zone VAV Systems, Attic Radiant Barrier, Extra Insulation. Within a year the CAD5 was replaced by a thing call WiFi…. Who knew? Drove my builder nuts in the process… but he survived and we are still great friends today. Appreciate you sharing the good and bad of your new home construction.

Great that you also share the things that did not went so well! Think that helps a lot of us not making the same mistakes!

Thank you for sharing all that info, the good with the bad!

Very different experience, but with the same goal: A house with zero net energy use. I started with a manufactured home with excellent insulation. Added my DIY solar array (5 KW) and a grid-tie inverter. Built the solar panel ground-mount myself with free engineered plans from a solar hardware company. Got it approved and permitted myself. The only outside labor was a concrete pumper, and a local engineer to stamp it okay for $25. Dug my own electrical trench by hand and the array foundation holes with a Home Depot rented mini-excavator. Wired to the inverter right next to the existing breaker box. Passed inspection the first time, and it was up and running. Had the propane guys come and remove their tank, and then converted everything to electric. Flash water heater, induction burners, convection oven, microwave, air fryer, Instapot, dishwasher, washer and dryer: We have everything a modern kitchen does. A heat pump would be nice, but for now we just have window ACs and electric heaters for the rooms we are in. After two years: Never had an electric bill, and the electric company owes us over $400.

I'm really impressed on what you came up with! I've had solar 9kw and a powerwall on my house for 1yr this August! The one thing I wish I knew was about a SPAN panel and 1 powerwall was on the very edge. I live in Connecticut and haven't had an eversource bill since February. I'm doing this for my mom as I'm her caregiver. I wish you could help us but I know you are very busy.

Don’t kick yourself too hard! Remember, we are none perfect! I bought an older house, so everything is put in, the best, that I can, with the existing structure. The recently installed heat pump, is a very welcome addition! I look forward to seeing how all this tech, works for you! Keep your smiles on!

Amazing details, thanks for sharing the lessons learned.

That smooth, sloping driveway is an energy saver when it comes to snow removal. It will help melt thin layers of snow and ice, even below freezing, and sublimate even below 0 degree F. But the loop I have always wanted to study is a heat pump loop under the drive and walks for heavy snow/ice removal- or even prevention. Safety is great, but such a ground loop has to be more efficient than conventional snow removal methods, in so many ways! Thank you, much.

You really should do a crossover episode with Matt Risinger! He's a home builder with a great channel and he's really big into passive house tech, as well as several of the other issues addressed in this episode.

Matt, I thoroughly enjoy your channel and content. Thank you.

Hi Matt, I have already done this up in Maine 6 years ago. the machinal room is in the middle of the house. here are some problems we have learned. the floor in the utility room should be sealed and have a drain. my water heating system has a lot of vibration with the compressor. both in terms of sound and micro formic transmittal though the building. you need to max out the sound proofing in the walls. isolating the equipment with damping materials.

From my own experience I’ve learned to consolidate the utilities as much as possible. That planning enough space as possible is essential. You learned from your own experience. Getting critical details in advance from your installers helps too. We didn’t get the details about our full propane installation. They installed the propane side but wouldn’t connect the water/boiler side. It was going to cost twice as much to continue. We told them to take the whole thing out including the buried tank. Communication is key. Experience is a great teacher. Go with your gut. It knows more than you do.

We just built our home and I put in conduit from the upstairs space to a place close to the electrical panels. I haven't installed solar panels yet but easy access between the roof and the electrical panels is important. I am surprised you didn't have the roof insulated so the whole house would be within the insulated envelope. More and more homes are doing this, making things easier. Also surprised that your mechanical room is so small, note you could have an issue with the heat pump water heater, it requires a great deal of air circulation to function properly. I would suggest you read up and verify that you have sufficient air for the heat pump water heater. As you note, JMO

Always follow your gut instincts. Take a step back and think out of the box. I acted as GC for 2 large additions to my home. I had to hang the drywall on one addition when I could not get any drywall contractors to return my calls. I had 26 solar panels installed in March 2023. So far all my electricity bills have been zero. Keep up the work. I look forward to more updates.

In my father's home where I grew up there was a large deciduous tree on south side in the back of the back yard. There was a sunroom on each floor. The leaves used to fall off in the fall 🍁 allowing the sun to help heat the house in the winter and spring. In the summer and fall the tree shaded the house preventing the house from sweltering in the summer.

Putting the electrical panel inside the house has one key advantage: It isn't out in the garage. Garages get hot in the summer and cold in the winter and can vary wildly in temperature in any given 24 hour period. That fancy-shmancy electrical panel has a bunch of fancy-shmancy electronics in it. And fancy-shmancy electronics don't like large hot/cold temperature cycles, especially capacitors and lithium ion batteries. You want those to remain in temperature controlled environments like the indoors where central AC and heating can maintain a more narrow range of temperatures.

At the church I used to go to they planted evergreen trees on the west side to prevent the prevailing west wind from heating up the building in the summer and cooling the building in the winter.

Good video! I just installed a 15kw solar setup on my barn roof, and ended up with a stupid main feed between the main panel and meter upstairs in the house, via a sub-panel in the basement and new sub-panel in the barn. Running into grid over voltage issues now, hopefully the grid company can step down the transformer a bit... No batteries yet, the systems available here are too expensive and does not do what I want them to. Hopefully I can add that in a few years! For now I'm really enjoying my consumption from the grid being reduced by at least half on cloudy days and up to about 1/6th of what it used to be an sunny days, thanks to home assistant moving loads around. Still a lot of work to do an that thought, and winter is going to be interesting.

I have found that D.E.T technique is usually the best. Do.Everything.Twice. Coats twice as much, but you learn from your mistakes, and so the second time around, you correct them.

Missing One! SCIPs Structural Concrete Insulated Panels! Designed the basics for a new home built in NE Texas. Insulated Concrete Box then add a standard roof. SCIPs have an Expanded Polystyrene Core with concrete sprayed on both sides of the foam. Not only do you have, probably the tightest structure available, but the increase in energy efficiency with the concrete Thermal Mass facing the interior of the home. The Concrete Box: Walls and Ceilings build with SCIPs. In the design we had 12ft high SCIP walls with 24in high cold rolled steel galvanized truss to support the SCIP layer above which were sheet rocked. The truss area doubled as the HVAC return air, charging that upper thermal mass. No air return ducts just return grill with filters. That home is off the electrical grid with panels!
