Top 10 Most Efficient Home in America

[@jackjmaheriii]

I don’t know why, but the passive house stuff is always my favorite!

[@sociopathicnarcissist8810]

I'm sure that part of that favoritism would only be enhanced if your electricity bill read $0.00...

[@MATTINTEXAS19]

I can see this happening in the north... Can it be done in the south (Austin, San Antonio)? I just don't know why more people don't demand houses like this or similar.

[@jackjmaheriii]

I was stationed in San Antonio for four years, and I would have loved an extra layer of insulation in my house. I wonder how much more R30 walls and R50 lids would cost?

[@anthonyman8008]

You're my favorite

[@alexclark6768]

i would love to see a cost breakdown of his entire house. and how much he saves each month vs how much it cost to build the house

[@rafflesmaos]

Something to keep in mind is that such houses are not just for saving money (which I'm not sure is yet possible in all cases), but also for quality and comfort of living. I don't think anyone can reasonably dispute that mechanical (ERV/HRV) filtered ventilation is superior to that which might seep through cracks in a normal construction, or that it's nice to sit next to a window that won't leak in the worst storm nor condense moisture in winter, or that it's great to not be able to hear street traffic outside due to the thickness of the insulation and windows. For some those things are worth paying a premium for, and at that point any other benefits like no energy bills are just a nice bonus. That said, I think it is possible to build such houses at a very minor (5-10%) premium over typical construction if one is careful.

[@LongLiveOurBuildings]

Agreed, some people buy a sedan, others buy a Mercedes, we all have different values

[@AJourneyOfYourSoul]

You will never get your money back in a house like this during your life time. They cost way too much to build vs what you save when you take it to this extreme.

[@LongLiveOurBuildings]

Tough question at hand - because what you YOU compare it to? What is the actual cost of a house DONE RIGHT? Is a code built house your baseline? Would you live in a code built home? For this client, money is important, but more important was his non-dependence in his future on energy companies. He now lives out his life with no energy bills or dependence except for the sun to rise everyday. What's the price tag on that retirement plan? I'll answer for you - PRICELESS?

[@alexclark6768]

plus, the resale value of a house like that stays a lot higher then a code built house.

That solves a theoretical dilemma I've been pondering in my future home. Thanks Matt!

There wasn't much discussion of the solar panels but I would assume they do not have a house battery and the grid tie in is 1:1 rated. Meaning for every kWh generated one is credited. From 1:11 there are 35 250 watt solar panels for a 8.75 kW system. This makes sense for more Northern sun hours of 3.8 and to charge the EV. The average house uses about 30 kWh per day and this home would be producing about 33 kWhs on a sunny day. The efficiency gains from direct solar heating probably on their own make up a big chunk that would be needed to charge the EV. Also heat pump water heaters alone would save 5 kWhs. While we got a long way to go for energy storage we can clearly see rooftop solar is plenty of power for all residential energy use.

[@Rayfanz1]

I like that they still installed ceiling fans throughout for “people” cooling and can also aid in heat/air distribution. Here in Texas even the most energy efficient homes have fans everywhere. I see it less in videos of northern homes. Also the fact the so many windows are operable for when you just want good old outside air, really makes it for me. Amazing place.

[@stevenbaczekarchitect9431]

5 years in Massachusetts with no heating bills now that is amazing! When I lived there 3 years ago my heating bill was around 150 a month in the winter for a one bedroom apartment.

[@filipgaliza8477]

I see a lot of people asking for a cost breakdown but please keep in mind that depending on your zip code, the price may be dramatically different. Also, even if you can't achieve a passive house certification, pushing your home to be as "green" as possible will give you a noticeable difference. Smart planning with an architect, smart product selection, and so forth will give you terrific results. Cheers!

I lived in Boston for a few years. It has hot summers and frigid winters and it's not sunny every day. This appears to be a fairly modest home in a normal residential community, not a multi-million dollar research project or millionaire's play thing. The man has net zero energy bills and does not need to put gas in his car. I know the initial investment in the home construction is probably greater but...damn...

I live in sunny southern California, and I'm an evangelist for radiant barriers. I encourage my neighbors to implement this oh-so-$-inexpensive tactic, towards tempering heat extremes. We live in a dry sunny climate, entirely different from Boston MA. So anyone who lives in a hot dry climate can exploit radiant barriers, unless he already has solar panels galore; they actually compete to keep a space cool. But a radiant barrier ALSO works the other way around, to keep a space warm over night, and over winter. I saw no mention of radiant barriers in Mr. Roy's project, and I suspect that radiant barriers are of no interest in Massachusetts. Let me know if anyone "does this" in Massachusetts. I'm about to have my 32-square roof changed, after 27 years. And we will figure out how to implement radiant barrier on OSB, without removing the space sheathing that my house possesses, from its original construction date of 1964.

[@jmmspeaks]

We needed to solve the humidity problem in our basement and were tired of using the old technology of running a dehumidifier (which costs a lot to operate and never gets rid of the toxic basement air), so we decided to buy a product called the Breeze. It has a gentle exhaust fan (115 cfm) that is rated for continuous operation, controlled by a humidistat. Instead of treating the toxic and humid basement air, it exhausts it, creating a vacuum that draws the "conditioned" air from the home's first floor into, to take its place. The results are nothing short of miraculous. The air quality in the basement has improved dramatically and we've been able to unplug the energy drawing dehumidifier. The Breeze costs pennies a week to run. No filters or drains are needed. The company sells one and two-fan models that cost from $299 to $449 and carry a 5-year warranty. I strongly recommend the appliance, especially if you’re interested in energy efficiency. It's available on the company website (breezesystemsinternational.com) or on Amazon and Ebay. Much cheaper than the $1,500 to $2,000 units sold by Wave Ventilation, Humidex or EZ Breathe. Now our dry basement also has healthy air!

[@mountainbikerdave]

@@Bryan-Hensley well luckily A passive house only cost 5-10% on average more to build then a traditional home. but thermal efficiency is not everything, that only impacts the heating and cooling costs. (which I am aware of is the most significant, 35-70% of a homes energy usage) but there is also electricity, water, Gas, sewage, trash, property tax, HOA(yeah right), cell phone, and internet. I must get rid of them all, all these bills must die! :)

@@mountainbikerdave that's kinda funny. I just asked a builder I know and he said 40 to 70 percent increase in price depending on how far you wanted to go.

True R value for 2x6 Wall --- R-11 Wall is 60% insulated --- R-22 (fiberglass or cellulose) Wall is 25% solid wood --- R-10 Wall is 15% windows and doors --- R-2

[@OlivierBL]

In north east R-22 is rather low, maybe even under most code minimums. This construction's walls probably hit R-75 (this is what PassivHaus projects hits up here in Quebec). Its probably not 2x6 walls but 2 2x4 with a good foot of insulation in between and no thermal bridge. And he said his windows were R-7+ and they are smartly arranged so that they can let the sun in many hours a day (only when needed)... There is no way he would have got a passive certification with R-11 walls.

[@grahampye2314]

I love the Passive concept. I would love to see a project that takes a suitably positioned home (most glazing facing South and nothing shading the sun) that was built using standard construction techniques and renovates it to incorporate as many Passive House principals as possible. If you need a home to do this project, I have one...

[@LongLiveOurBuildings]

LOL, I do that almost everyday

[@2awesome292]

So build a new traditional house, gut it, then make it passive?

[@grahampye2314]

In my case I have a house built in 1989, it has tons of windows facing South that are at the point they need replacing, the walkout basement (lots of south facing windows too) needs refinishing after a flood... this sort of scenario seems perfect for upgrading windows to something suitable for passive-solar, but beyond that the reno would need to add some thermal mass in the right places, upgraded insulation, perhaps tweak mechanical systems... etc.

[@2awesome292]

Upgrading windows is possible. As far as adding insulation, you would have to tear out all the walls (to put on inside) or remove siding (to put on outside). There is a airborne system out that can fill in some of the holes in the envelope, but i'm not sure about effectiveness is when drywall is already up. Adding thermal mass would be pouring concrete inside the house? You can't usually tweak mechanical systems besides sealing. Changing capacity would usually involve replacement. You can't just replace one wall, you have to replace all of them to get maximum effectiveness. Analogy: If you have 4 water leaks in your pipes, you can't patch one and expect your house not to flood. Look up chainsaw retrofit. That would be the ideal scenario if you need new siding, roof, and mechanicals at the same time and want to significantly decrease your utility bills and increase interior comfort.

[@cloudyeight]

[@lavectech]

Nice house, great work. Heat pumps are best to be indoors? I read they need to be in a large room?

[@alec4672]

I think the reason Dan's is such a perfect case is because he understands and cares that he has a passive house. Going passive takes just as much attention from the homeowner as it does work from the builder. Not to say going passive is allot of work but I'm sure Dan checks all his numbers and keeps good track of the efficiency he can spot when something is wrong and usually just from the data know why.

[@LongLiveOurBuildings]

I would argue there aren't many people that understand their house better than Dan does

[@fuzzygreysocks]

Agreed. These para-off grid homes are capital intensive and demand more attention from homeowners than less efficient conventional homes do. In our domestically transient society there will be a very limited niche market possessing the inclination for the additional maintenance and care. Such buyers would MORE likely just build their own design than trust someone else's X-years old tech + questionable maintenance. The aging-in-place aspect, although romantic, will be harsh in another decade when Mom & Dad probably should hang up their car keys. These are custom made sports car homes.

So this house doesn't have any battery storage for lights after dark? Is it feeding enough back into the grid that it zeroes out? I live in southern Peru and am fascinated by passive houses but there are no builders here and the weather is so nice that no one even has centrally AC or heat. Small space heaters a couple times a year for higher income people are more than sufficient, but electricity is very high per kWh (about 18 cents USD right now). The thing is its super dry so very dusty. The air quality advantage is very interesting more than passive heating, although air/heat distribution throughout the house would be nice since lower floors can tend to be chilly for cold-natured people. I have a 1.3 kW system and a small lead-acid battery bank (1000 ah) and my grid electricity is running about $20-25 per month for 2 families and 8 people. There's no net metering yet here.

In 2012, I added solar to my home, bought an electric car and moved to heat pump appliances, with gas basically as a back up. Initially, when my parents passed away, I put the inheritance money in the bank making less than 1% interest and paying tax on that income. Instead, I moved to solar, which generates $2000. of tax free energy per year, which feeds my home and electric car. An 11 year ROI. Like this home, I produce more energy than I consume, and receive credit for this excess production, Solar is a enabler to move away from fossil fuels for most of our needs. My home is in the south, so cooling is my focus. My only regret was not going solar earlier.

It frustrates me so much that Australians don’t take PH stuff seriously. I have a property that I purchased that was built in 1979. I wanted to look at improvements in efficiency but I was told it’s good enough as it is. It’s a double story (on a suspended 8in slab) interior walls down stairs are bagged cinder blocks while upstairs Interior walls are 10mm of cement render over cinder blocks. Exterior walls are the same as interior walls plus 65 mm air gap to a solid external brick. It needs new windows as they are original and I wanted to re-clad over the painted brickwork with a type of cladding, I thought I could insulate between the bricks and the new cladding. The home is lucky it has such large rooms as I’m sure something could be done to the interior walls too. It just seems people are happy waisting there money on purchasing massive ducted HVAC systems. 🤦‍♂️

Does the cooking smell linger longer in a Passive House?

[@stevenbaczekarchitect9431]

Constant mechanical ventilation in here - because of it's air tightness it actually performs better

Would love to have heard a discussion on the payback period for this passive house. Also, how many square feet are we talking about for the 7.5 KW solar system? And where were the batteries and what is the maintenance interval for replacement on those?

[@LongLiveOurBuildings]

No batteries, house is about 26oo sq ft

[@paperwait9611]

if you live in an area that supports net metering, maintaining an energy storage system doesn't really make sense. the problem with assessing "payback period" is the artificially low energy prices in the US. so the "payback" doesn't look as favorable as it would in europe where energy prices tend to be higher. the problem with artificially low energy prices is that it encourages wasteful use of energy or at least provides little incentive to go out of your way to be particularly energy efficient.

[@keninatlanta8452]

@@paperwait9611 what is it that you're referring to that makes energy prices artificially low?

[@paperwait9611]

@ken in atlanta: energy is more heavily taxed in europe. there are a number of "externalities" costs that go beyond the cost of delivering the energy. higher taxation of energy recaptures some of those externalities costs and encourages more efficient use of energy. for example, triple glazed windows make more sense in europe, but if you go to a window store and ask to purchase triple glazed windows, the salesman would probably think that you were crazy for spending extra money above the cost of double glazed windows.

Nice installation quality. Even though we have this a lot in Europe because of code, the execution of ventilation systems is not always this great, so congrats.

For this house, you mentioned that Mcekroy windows were used. What brand/manufacturer were the doors that were used?

[@jon8864]

Need to talk about the "building science" of passive houses. The water barrier and air barrier are different to the other houses you talk about.

How did you go about getting a r100 in the roof?? Please and thanks!!!

[@stevenbaczekarchitect9431]

30" blown cellulose

[@juzoli]

Steven Baczek Cellulose can only go up to R60, it collapses under its own weight above that. How can you still go up to 100?

[@ryangarner5804]

That is awesome. Great work.

You should do a video on the pensmore mansion.

What is the life of the HRV system. What happens when it stops working or needs repairs or service?

[@stevenbaczekarchitect9431]

Kinda like a refrigerator, get it fixed or buy a new one......
