We stayed in Pasivhaus in Germany for 3 weeks and after it, I am just desperate to live in one of these in NY. The air quality was so great and everything was silent. I haven't slept as well in probably 20 years (I am 40). Instead, I am stuck in NYC with wall-through-AC and metal frame windows and banging pipes during winter and loud AC during summer :(
A wonderful graphic explanation of Passive house ventilation. May Asthmatic Passive House occupants report that they can leave their inhalers at the door, because they only need them when they leave their healthy homes.
YES this can be used here in Brazil, please note"PASSIVE house" if your home/house is constructed as a tight envelope (minimum leaks etc) then an ideal system for HVAC could be designed. But,take into consideration the route of the ductwork (pipes)
Constant air flow is not a great thing for comfort in the shower (it will be super cold due to evaporation), unless you have a steam shower and can totally seal the shower cabinet.
Passive refers to the Pasivhaus building standard where a home is built with high insulation and air tightness. Usually this also means that the house does not require any heating system as solar gain and waste heat from occupants body heat and appliances provide when combined with heat recovery ventilation are enough to heat the home. My home is an NZEB (net zero energy building) which is a near passive standard of building. I've never had my kitchen air temperature drop below 18.5C even when it was below -5C outside.... without using any heating system. The heat recovery ventilation only has two small fans that use an average of eleven watts of electricity vs the thousands to tens of thousands of watts a gas/oil or electric heating system would use.
Adham Tamer its the pressure and draft, the house is so tight that its not legal to build these in my country without the ventilation system, before we moved into our passive house here in may, it was checked by a certified expert who performed a blower test , the house is set under pressure with a big blower and it must be totally tight, its possible to even dry laundry in the living room without any risk of mold , a sensor is monitoring the exit air for moist and controls the speed of the air blown into the house. the monthly expense of heating is only 60 dollars eventhough we live in a cold country , i came from a traditional house where we spend an average of 220 dollars a month. on top we have a tax reduction due to the use of electricity as a part of heating (air to water compressor system )
Electric fans. The ventilation fan in the bathroom and exhaust fan in the kitchen connect to the house ventilation system which has a make-up air fan inside of it.
yep, and also look up Daikin HRV demo video, it has some interesting modes. However conventional air conditioning systems use recirculated air, so ventilation can be expensive.
Now 2020, an ill occupant (with COVID-19) would need a neg-air type bedroom to prevent virus spreading throughout the whole building requiring dirty air in the bedroom be drawn away as far from the entry door as possible and behind/above the bed headboard. Fresh air would be provided at the bedroom entry door; however, usually supply HVAC is piped in at a window location; so, some kind of switch needs to be installed for diversion needs (normal flow versus illness).
You want the intakes in the kitchen and bathrooms because those are the rooms that produce odors you don't want going into other rooms. In a conventional older home the walls are so leakey they don't bother to bring in fresh air at all. It gets sucked in wherever it can. Better to have the house be air tight and control the fresh air.
i think its considered 'dirty' AFTER you exhale CO2. The air has been filtered already. The vents are in the bathroom and kitchen since that's where the most humidity and odors come from. You could just as easily add more exhaust vents. I live in south Texas so, we would still need AC. Not sure that this would work in a hot humid climate. Plus retrofitting would be a pain in the ass.

Great video! Really helped me understand how ventilation systems in a passive house work.

true
Brilliant! 👍🏼If you are interested in this, then you should also look for and is available. The Wind-catchers of Medieval Cairo and its Secrets.

I would rather have kitchen vent directly outside on its own. The grease from kitchen fumes might damage the entire ventilation system.
fantastic! l'd like to know if this system could be found in Brasil!!!

Cool house😊
Seems like the Input/output ventilation is awfully close.
In the tropics we open our windows for fresh air...but make sure there is insect screen for each window
Why no gutters?
No eaves over windows to cut hot sunlight in summer?
How is this passive? Does this system not require a blower?

can someone tell me what makes the air move in that specific route

adding HVAC to this would work right?,,,,,,, cooling from a 71 degree F temp would be easier than from a 100 degree environment I would think

Who cares about COVID, it is statistically indistinguishable from other respiratory viruses unless you are extremely old or overweight..
@@sickre he cares because intelligence op's and media propaganda made it scary to him.
Run a bath or a plastic tub with some cold water. Use that to dunk yourself throughout the day.
There's an idea. lol🤣
Hai
I doubt if the house shown in this video would meet the PassivHaus standard with the extensive flat roof.
its clearly a pitched roof
The pitch of the roof has no bearing on whether a house is a passive house. We are designing flat roof houses and apartment buildings in Philadelphia.
wow! i am poor
fredlee john high-five mate. You are not alone 😕
Harpal Singh My condolences.
i do not like the idea of 'dirty air' funneling into the kitchen where food prep is done.
it's only "dirty" because it's traveled through living spaces. It's still filtered air from outside.

This is not passive
