Great video. I feel relaxed now. I really like the overall design, and the design details. Very well done. I also like that the family has lived in it for 8 years, so they have a lot of experience in the house. They didn't see any problems with it. I had a drafty house, then insulated inside the walls, and added home-made window-film frames (3M film that you tape down, then get rid of the wrinkles with a hair dryer.). That made my house the same temperature everywhere, so I could lower the temperature. After doing that and caulking all the cracks, my heat bill was reduced by 2/3. If I could start from the beginning, I would like to do something like this, or maybe earthen walls.
that sounds awesome, the way you've insulated your house. Indeed, the next time I build, I'll consider far better the insulation and reduce the heating/cooling as much as possible
FYI 'passive solar' is a completely different concept to this video (typically relying on thermal mass) this is 'Passive House' thermal mass in a passive house could potentially lead to overheating so it is not required
We are considering building a passive house in NL. We are in the process of looking for a suitable building plot. If you were to extend of offer, we would be delighted to visit your home in BE. Thanks
I couldn't quite catch what the internal walls were made from. Could you provide a few more details please. Was there a vapour permeable wrap on the external and, separately, on the internal walls? Also, does the cellulose compact over time? How was the cellulose placed in the wall cavity? Blown in? Thanks for the video. Beautiful house.
@@MindfulBuildingandLiving He says it at 5:30 and again at 5:41, but his accent is so thick it's not decipherable. Sounds like "low finish," but obviously that is not a thing. Anybody have any ideas?
@@Thoracius no not dirt panels. The walls are wooden structures and finished with loam. That's like plaster, but a natural product. Here you see how loam (or a mix of loam and clay) is applied to a wall ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bJ8l3Of3hyU.html
yes it is airtight to stop uncontrolled air infiltration, fresh air is still supplied via a Mechanical heat recovery ventilation system which can recover a min of 75% of the outgoing heat which is how it is able to maintain comfortable temperatures inside with minimal or even no heating, heating is able to be provided simply by having an electrical resistance heater in the air supply duct, it can even be provided by a heated towel rail, depending how many people live in the home (more bodies = more heat generated) and its size determines how much heat you may need or not, this video doesn't mention the specifics of the ventilation system too much, but it is a requirement of certified passive houses.
this sould be the standard in all countrys , i live in the uk and our government are bleating on about going net zero carbon by bla bla bla ! yet if you go to look at a new built house in england there are zero homes built to this standard on the market . [ i will say the only place in the uk that promotes this type of home seems to be wales . as they do give eco home grants and will pass plans for sustainable desings where i live i asked if i needed council permission to put solar pannels on my roof . my local council did not even know WTF i was talking about !!
The average efficiency rating of a UK home is a D or E (on a scale from A most efficient to G least efficient) most homes have solid walls with no cavity,p let alone insulation! The average roof insulation is about 10cm! Forget heat pumps, our builders/plumbers/installers can't even get gas boilers done right! The average boiler is less than 80% efficient even if the boilers are 90% rated because the set up is all wrong, not balanced. Some of the poorest people in the UK have homes so inefficient that they would be impossible to heat with a heat pump. Some of the poorest renters are forced to use electric heating including for water that is literally up to 4 times more expensive than gas (some homes have no gas supply) or they have oil heaters which is just utter nonsense in this age. The new homes are better insulated, usually rated a B (in reality more like a C or D) but the quality is so bad (not as bad as US disposable homes but still bad by European standards) this is all a mess really, such a wasted opportunity. All Jones need to be upgraded to at least a B now. It would boost the economy and reduce it reliance of dirty Russian and Saudi fossil fuels for a start
you can call it "energy efficient" or "sustainable" but its active heat pump means its not passive home.. and key elements for a true passive home, such as "thermal mass" are part of this home too.....
"better"??? what does "better" have to do with the word "passive"? HP is active ie its not passive... end of discussion... all the rest is BS... so have fun down your rabbit hole being obtuse about it... bye Alice... FWIW Trump would proud of you :)
@@nc3826 passive house is a standard. a home can be certified as passive. it's good that you want to be BETTER in energy saving but YOU don't set the standard
@@MindfulBuildingandLiving But that shredded paper likely do. Even if the manufacturing went through bleaching and removed the solvent from the ink, it still will contain some acid. In the end it will not affect the health of the occupants of that home, since the off-gassing is likely minimal and going off toward the exterior in the summer days. If they do not sniff their walls they will be fine. ;)
@@MindfulBuildingandLiving WADR the OC was an anti=environmental trolling conspiracy theory with no basis in fact... that you should t not encourage IMHO.... While its not really a passive house, since it uses a heat pump... I admire what your trying to do... And good luck with your future efforts...
It’s totally fine. He has a air circulation system. Itprobably has way better air quality than most homes. He said he can’t smell his cooking remaining in his kitchen. So it’s highly unlikely that any such gases will cause problems. Also I doubt if these papers will cause problems unless they got wet
@@MindfulBuildingandLiving They are variable speed heat pumps that do cooling and heating. I'm sure they would work well with passive houses to fine tune your comfort.
Why no reason? Passive house is not only about low heat/cooling loads but low primary energy demand, high indoor air quality, temperature stability in blackouts. Also if you disregard passive house principles, you will need a larger heat pump which will consume more energy even if its efficient. A 1.5 ton dual stage heat pump will be more efficient than a 3 ton VRF unit.
