Passive house: 65° in winter with no heater 😱
Вставка
- Опубліковано 1 жов 2024
- It's been in the mid to high 30s the last few days here in the Denver, Colorado area. Our #passivehouse has been staying at around 65 - 69 with no heater. Our mini-split system is needing to be repaired so we turned it off. Even with it getting down into the teens at night (17 degree last night) the house is still staying incredibly comfortable.
I will be a releasing a deeper dive with data with Enrico from emu.systems shortly. This house retains heat so well. Especially if we get even just a little sun during the day.
Awesome! We need more Passive Houses!
Hopefully as more people build and share their experience it’ll encourage more people to choose passive.
We need all
a solar collector for warm water would really supplement the passive solar heating you have going now with the windows. a neighbor of mine has a system like that that uses glycol (antifreeze) as the medium. on partially cloudy days he still gets temps of 65C coming in and in the neighborhood of high 80's to low 90's on clear sunny days. a large water reservoir to hold the warm water for release at night would be the ticket to really cut down your heating bill the only energy the system requires is an electric circulation pump to move the water
I’d love to see a video of how the system works. Let me know if you can record it and share.
@@thesharingeconomy also in denver.....solar collectors are all over youtube......i would also try solar chimney for cooling
There isn't enough info out there about passive houses. So many competing design theories. Really appreciate the performance/quality of living details. Good looking house
Thank you!
I personally would find 65F too cold in the winter. I'm spoiled with radiator heat in Chicago and the "coldest" my apartment gets is 74F. When the heat kicks on it can get to to 78/79. On the coldest days it's not unusual for my temperature reader to get to 81. I turn the heat down at night and crack a window.
I definitely see the value in passive house design. At the very least incorporating this design can cut energy consumption if people choose to have AC and heat. I'd probably want radiator heat if cost wasn't a factor.
Just brilliant. Job well done
Thanks! This house was a labor of love. I'll continue to upload videos outlining how it was built and the decisions we made through. As well as performance and cost.
@@thesharingeconomy : fantastic. How good would be the performance if there was outer insulation instead of double walls?
An immaculate house, while visually impressive, can sometimes reveal underlying obsessive-compulsive tendencies in its owner. This excessive cleanliness and order may stem from a deep need for control, routine, and perfection. For individuals with OCD, maintaining a spotless environment often provides temporary relief from anxiety or intrusive thoughts.

"One cannot
Lick well,

Pooped well."
Psychoanalytic observation has launched a long tradition in medical literature that links constipation with obsessive-compulsive traits. The wife should worry less about order, learn to be happier in chaos and stop obsessing about control. Not only will she live longer, but happier.
Performing well it seems. Curious about the glossy paint on walls and ceilings.
How much extra did this home cost than a regular home? Guessing at least 35% more which would be around 150k-200k? Then how many years would the payback period be? 30? Yes in the long run the house will save enough energy to make it worth it, but considering most home owners only live in a house for 11 years, they wont realize the energy savings.
Its not just about paying back, its about being comfortable all year long.
@@ssaini5028 That's fine for people who can afford it, but what's ironic is that the sales pitch is what attracts people who cant. Perfect example of spend a dollar to save a dime.
@@MrRerod Agreed, crazy sale pitch. Passive homes avg $200 more per sqft on the low side
@@ssaini5028 Ive read about a home that came close to passive house standards with 6" walls. What Ive learned is that air sealing is just as important as R-value.
@@MrRerod definitely, its possible to have thinner walls and still make the passive certification. Pre-fab concrete walls with foam insulation/Zipp
This should definitely be featured on the build show
That’s kind. It’s a unique house. We are excited to see how it performs when the mini-splits start working. But the house never got below 63 despite it getting in the negatives recently. I’ll post a follow up video.
@@thesharingeconomy i wish passive house was minimum code requirement especially in texas. Home prices have gotten ridiculous.
@h2s142 increased housing costs are fine. Long term with increased electric rates you save long term. Our glorious ercot overlords do an excellent job
@@ITRMUGENITRPassive houses are more expensive
What brand of windows did you use? I'm having problems choosing.
We used Alpen windows and doors. We have had a significant amount of issues with our doors especially. Our internal lock is frosted over in the morning. Alpen are at a very good price, but I may have splurged with a higher quality manufacturer if I had to make the decision again.
you should've imported the doors and windows from The Netherlands. we have better doors too with locking pins attached to the hinged of the doors and extra rubbers to stop water from getting in between the door. @@thesharingeconomy
@@thesharingeconomy the walls are 20 inches thick. concrete shell - insulation - brick. the first and second floor are both insulated concrete which is still unknown construction in the US and same goes for the wall construction. BTW the windows are quadruple pane since it can get pretty cold out here. hope this was a little informative :)
Great and informative video.
Nice house by the way!
Kind of Scandinavian look.
Greetings from a wintery Sweden.
Thank you! I grew up in New England in the USA and the white siding is common there as well. We tried to balance a modern look with it still fitting into the neighborhood reasonable well.
Great efficiency, seems like you could just bake a loaf of bread and the residual heat would warm your house
It is amazing how effortlessly it stays warm! One other challenge is that the same thing is true in the summer, where it takes a bit of time to expel the heat that builds up. We should have put a fan at the top of the house by where the lofts are so we could vent the hot air up there when the sun goes down and switch to opening windows to get cool air in because it does take a bit to cool the house down. It really loves keeping the heat in.
Very nice open plan house. Awesome.
Which type of insulation did you use? Nice video.
We used blown in insulation for the outer wall, the gap, and the other exterior wall (two 2x4 walls with a gap between). Then there is the air barrier, then we had regular batt insulation for the interior/mechanical wall. You can see more details here:

So there is no heater whatsoever in your house?
We don't have a traditional furnace. We have a mini-split system that uses electricity. Also called a heat pump. These are small units and operate from condensing the heat from outside (even when it's really cold outside) and releasing that heat inside. We have four of these mini-splits at various spots in the house, despite only usually running two of them for cooling during the summer. We haven't had a real test of them in the winter as they were not working during our first two winters. Despite not having the heaters working those first two winters the house only got to 53 degrees (the coldest spot in the house) despite it being in the negatives outside. As soon as the sun would come up, the house would reach the mid 60s. Pretty amazing despite the heater not working.

Great question! Doorbells we can ring for different rooms in the house, with labels that are meaningful to us. Unrelated to the passive house 😃
@@thesharingeconomy genius. Putting one on each kid room.
