What Is A Passive House And Why You Need It (4K)
Passive homes have gained significant recognition in recent years for their innovative and sustainable design principles. These houses are not just another architectural trend, but rather a response to the pressing need for energy-efficient and eco-friendly living spaces. With an emphasis on reducing energy consumption, passive houses have become a beacon of hope for mitigating the environmental impact of residential buildings.
The concept behind passive houses is simple yet revolutionary - to create homes that require minimal heating or cooling systems. By implementing a well-thought-out combination of insulation, solar energy utilization, and efficient ventilation, passive houses are able to maintain a comfortable indoor climate year-round without excessive reliance on fossil fuels.
One key feature of passive houses is their air-tightness, achieved through the use of continuous insulation and high-performance windows and doors. This not only prevents heat loss in cold weather but also keeps the interior cool during hot summer months. The carefully sealed structure ensures that external elements, such as drafts and pollutants, are kept at bay, resulting in a healthier and more comfortable living environment.
Another essential element of passive houses is their strategic use of solar energy. Large south-facing windows and properly positioned shading devices allow for optimal solar gain during winter months, while preventing overheating in the summer. Additionally, the inclusion of solar panels on the roof contributes to a considerable reduction in energy consumption, as passive houses generate a significant portion of their own electricity.
One of the most fascinating aspects of passive houses is their reliance on natural ventilation systems. By incorporating heat recovery ventilation (HRV), which continuously exchanges stale indoor air for fresh outside air, these homes maintain a constant supply of clean and filtered air. The HRV system also transfers heat from the outgoing air to the incoming air, further reducing the need for additional heating or cooling.
Apart from their impressive energy efficiency, passive houses offer numerous benefits to their occupants. The superior insulation and air-tightness result in a remarkably quiet living environment by minimizing external noise penetration. Additionally, these homes prioritize the use of non-toxic materials, ensuring improved indoor air quality and reducing the risk of allergies and respiratory issues.
While the concept of passive houses has gained significant traction, there are still challenges to overcome. The cost of constructing a passive house can be higher in comparison to traditional homes due to the specialized materials and systems required for their construction. However, it's important to consider the long-term benefits of lower energy bills and reduced environmental impact that these houses offer.

What a beautiful and inteligent home. Sadly the camera man was filming an spech not the beautiful features on it. Congrats to the architect!
I’ve been struggling with so many passive house designs looking very “classic”. But this one I really like. It’s contemporary & filled with light. Something that I’ll use as a bit of inspiration for my own one. Well done!
If a passive house cost 25% more, just build a house that's 25% smaller (problem solved). With good attention paid to an efficient design layout you wouldn't even feel the reduced space, but you'll surely feel the passive house benefits.
You'd save money in the long run.
@@JamieHumeCreative For sure, and the smaller the place the quicker the savings
Thanks for the erv explanation. I am going with south facing large planter in my cottage. Plants give off lots of moisture.
Love the concept and the home!
You have a beautiful home. I hope one day I can build something like that for my family.
Awesome video, we are trying to build a small but very efficient home. There are so many ways to get there but the basics seem to run through.
Great video and besutiful home!
It is my goal a Netzero cabin, running here 💯 percent in solar energy for the last 10 years every year I improve a little in insolation , my 600 square foot kabin is being heat with a mini wood stove and electric infrared heating, hope fully in couple more year I will be all solar
Stunning
What did/does the house go for price wise? & from as someone from Wisconsin, what would a standard house about the same size go for in that area?
Very well thought out. Love it. Changing those lights? Guessing that would be rare and less dust.
Very nice and well presented tour of this house and it's construction. It all makes a lot of sense, even if I am not sure if this would strictly be a "passive house". What surprises me though is that it is presented as something new or out of the ordinary. All of this is more or less standard for all new houses in Sweden for the last 25 years or so. My house is even built in 1989 and it has the majority of the concepts presented here - heat recovery fresh air ventilation in all rooms (extract in bathroom kitchen etc and supply in other rooms), triple glazed thermal windows, fully airtight vapor barriers in walls & roof, very well insulated, foundations & slab insulated and with capillary breaking materials etc... So it seems this is not the standard or normal in Canada then?
Yes, this is a newer concept in North America. It's been introduced a long time ago here, but it isn't popular because of the added cost and care for construction and planning. Every house should be built like this, of course.
I like conditioned attics rather than blown insulation. The amount of heat and cold in that space is greater than outside a lot of the time. And that radiates into places. Where as a conditioned space helps radiate the indoor temps through out the structure.
Awesome! 👍😎🇨🇦
Hi, how did he deal with the kitchen cooker hood? Did he make it ducted to the outside? Excelent video.
What an amazing space! The most polluted air most uf us breathe is inside of our homes. I have large hepa air purifiers in every room. The line that struck me was "fighting a losing battle" with small appliance air purifiers. So true! Wondering if this sealed, passive solar house also good for reducing fire risk in areas prone to seasonal fires? Many people in northern California are building without fireplaces and limited entry points for a fire to jump inside the house. Now I want to build my dream house like this!! So gorgeous!!
Yes we actually had wildfires out west that spread over to Ontario last summer, and in the video we talk about that at 8:38
that amount of insulation is pretty standard now a days here in The Netherlands, we use brick on the outer walls then the insulation followed by the concrete. the tilt and turn windows are also everywhere here and the triple pane windows are pretty standard too. with new construction now a days you'll usually see quadruple pane windows to block the sun's heat or the cold from the outside and they're also required to be triple pane for buildings located in busy areas like city centers. a little while ago i was in NYC and i noticed they had dual pane windows everywhere, even the high-rises had dual pane and i could easily hear the sirens and horns of the cars outside so maybe it still has to do with regulation that North America is behind with this.
The rest of the world is so much further advanced with their building science!
@@KennethYimHomes yea, i hope that Canada and the US will catch up soon (hopefully)
Hey Ken.. Can we have a full walk through your of the house.. For us that Like floor plans 😊
This is lovely! What’s the ballpark cost from start to finish?
YOU COULD WRITE A BOOK ABOUT THIE CONSTRUCTON OF THIS HOUSE.
Now in Canada Yea!
Is the guy who lead the tour the owner/designer or builder? Or all? I love not using any materials with high embodied carbon. Such a nice house! How fast property like this sells and how much is higher price per sf/m2 in % than conventional 100+ yo in the same nhood? Thanks!
Yes the guy in the tour was involved in the project. It was built for his family. It's a beautiful home! I don't think enough people recognize the features of a home like this. I personally would pay the premium, if I could afford it. From the perspective of a home owner, it's worth it.
Are the plans for this house available? I know he customized it more given there's an identical building next to it I'd love to know. Being from NYC having a house like this is a pipe dream but i really don't like how the houses in my area are built and I'm exploring passive homes
The stairs are wrong. No toekick make them a trip fall hazard. This makes me wonder how they pass inspection. 2M in Vancouver BC. It's acclimated not acclimatized.
@@gregpendrey6711 I thought the same thing when I saw the stairs, stylish but dangerous.
Hi Kenneth, a quick question - what was this house built with? Is it concrete and masonry or timber framing? I'm asking from a soundproofing standpoint, it's so quiet so I was wondering what was it built with. Thanks!
Hi Alexander, it's built with wood on concrete foundation. They avoided any steel components for heat transfer/loss.
Tons of great features. Alas, too many words...
I wonder how much the house costs? What are the running costs?
Ray: "...you see the Control4 and the amount of real estate those systems take up and the amount of panels they have is just crazy..." 🤔 Control4 controls an entire property and every device in it with a handheld remote; Apple Watch; an 8" or 10" touchscreen; your own Android/Apple devices; your TV; or just your voice with no screens at all. You can literally control your whole home without lifting a finger. But if you prefer to get up and walk over to a wall switch and stand there each time you control something...Or stack multiple wall switch panels...(22:50) To each his own.
I recommend spending the money for thermal breaks around windows and doors. Any kind of insulation besides fiberglass. The condensation zone of moisture increases around big windows and doors as they increase in size.
If this house is certified Passive House, all thermal bridges are accounted for, not just around the windows.
Nice house and good features. I wish there was more house footage. I got bored to hear the guy talking all the time, that I had to mute the video and forward it to the end. Well, keep the good work guys.
If you muted the video, you're missing probably the most important aspect of what makes this house special. Otherwise, you're better off just looking for just beautiful interior design buildings. A Passive House uses about 10% of the energy cost of a built to code construction in North America. And has one of the best comfort and indoor air quality environments you can ever get, if not the best!
Good video but this is not a Passive House-certified building. Why didn't you hire a Passive House Consultant to make sure this home got certified? You might have been really close to meeting the requirements?
How about the cooking?
I got constant fresh air in my 200 year old house. I don't have forced air so not forcing air out. I have cellar doors I need to fix. I did put vapor barrier in crawl space and mineral wool along foundation. I put thermal break/vapor barrier under my brick paver basement floor. After I lowered it a few inches. I have a lot drier basement now. I white washed the brick too. I think back in 1815 they lived in the basement.
Apart from this artificial new terminology “passive house” to begin with Homes are supposed to have a natural ventilation and natural relatedness to the elements the temperature and the movement of the air and I have no idea why they called a “new “concept it’s as old as housebuilding…
Who was his architect and builder?
Self managed, using individual trades
window U 0,08 ??? i dont beieve it. i never heard that, might be 0,18
If propane or natural gas is used and respected, then your energy bills will be a lot less than if you only use electricity alone. Heating or cooking with electricity is crazy expensive. Build well, use solar power, EVR, and selective heating of water using propane. For example, induction stove are dangerous to your cells due to EMF.
Well they do energy arbitrage with twoTesla Power Walls. So that's 2.9 cents per kWh for electrical usage. You can't beat that! All the other stuff, EMF, that's debatable (not disagreeing with you, but hard to prove)
The house .... the house .... the house .....
Awesome house but the dang intersection lol
Cool house. Shame about the sound on this video!
It looks marvelous but I think it’s a way too complicated… It is like a ship with the main control system which has a lot of control elements, electrical solar, base, Tesla walls… Etc. etc.. That concept is to create a home that is so efficient in terms of fresh air and other elements related to environment and does not have any dependency on electric circuits and Wi-Fi because that is where of secondary unhealthy environment comes to the human you might be protected from unhealthy, fresh or not, but not so fresh air but the electromagnetic fields created by these electric circuits in the RFID by the Wi-Fi. I still are still very prominent health hazard, and I don’t see anything like that figured out for that. On the contrary this house is wonderful, looks wonderful in terms of element, fresh air, etc. but at the same time I think it is an electromagnetic field mind line, in terms of effect on the people living in it
If Tesla could build a house the proprietary panels they'd "engineer" to build the house out of would have so many irregular gaps that it'd have a higher air exchange than the average house. Oh, and all the doors and windows would lock when the house catches on fire.
LOL it's not about the hardware, it's all about the software.
Beautiful smart home , need a better videographer!
Thank you. Genuinely curious, what could improve about my videographer?
@@KennethYimHomesWhen the three of you guys were looking at the photos explaining how and why you started the building process. We saw none of that. He stood to the side so we couldn’t see what you were talking about. By the way I loved your house and how it was built.
30.52 was interesting 😂
The mechanical room?
@@KennethYimHomes the person walking down the above stairs.
I have doubts whether this is a true passive house cuz of the fan. A real passive house doesn't let the heat in
Your comments (“…cuz of the fan.” + “A real passive house doesn’t let the heat in.”) are not quite right. 1st listen to what he says about the ERV at 21 minute point and later. It is a sophisticated system that differs from conventional old style concepts. 2nd , The heavily insulated walls and energy efficient windows lose less heat in winter and gain less heat in summer. This house is designed to benefit from solar energy heat gain in winter. Listen to 39 minutes in. This is a well thought out design.
Nice, but why are passive homes always an eyesore and you built two of them.
exceptional work but working with double morale Tesla company is a huge downside
ABOUT THE INTECOMM system…..… have you considered the effect of the electromagnetic fields and Wi-Fi on the people living in the house? I’m sure you thought of that.?
Doesnt look good in this neighborhood tho...so out of place
You're correct. I can't wait to move into a cookie-cutter house the builder thought up, the tract housing is so wonderful and the workmanship is award winning!
I thought 0.6 was passive.
It is, it's my fault for calling it a Passive Home, it isn't officially certified for such. They built it using the Passive House Institute standards, and much of the principles and energy efficiency has been achieved.
.80 is still amazingly good!
0.8 ach50 is really good but passive needs to be 0.6 or below unfortunately, it's more like high performance house but definitely not passive, overall nice project,
Man…nobody told my guy his fly was open 😬
Haha shoot I told him after we filmed it. I just noticed it then. Good observation!
HAHA, it's happened to us all! Incredible home. Thanks for sharing! @@KennethYimHomes
Where's this? 4 mil house?
It's in North York. Great guess, that's pretty much the price.
The one thing you can’t see is the constant road noise……
26:12 road noise test
All Houses are Just chimneys by another name. They want to Naturally vent your expensive HVAC out. When you insulate correctly it stops that. But then you have another problem. An air exchanger solves that problem.
that non-passive house blower door score of 0.8 ain't lasting in perpetuity, lol. that's just silly and literally impossible.
He’s a talker…….
What a terrible camera person
