A very efficient house! But it has a pool, which is a huge waste of energy, water, and chemicals. Seems like an odd contradiction of conservation and waste.

I will say that I would just build a regular home and all the money I saved not paying for the passive bs I will pay normal bills for many many years.....

No such a thing as climate change and all this is doing is wasting time and money. Prove me wrong...

why does my friend insist of opening doors

Like the idea but why are these houses always so ugly?

trash and insane. ruing and changing society for the worse. besides the looks the function the purpose and the after effects of people owning these is what matters and its not good for what it would do to our society mentally and economically. post modern destroys the human sould and spiriit as well so even a darker and possibly more important reason.

I have a solar designed home in Perth, Australia, that I designed and built in 1988 without mechanical air conditioning, and with only passive ventilation. The house uses thermal mass and never overheats in the summer, and requires very little none passive heating in the winter. If it does start to get warm inside after a couple of weeks of 40+ degrees, I open the windows and use mechanical extraction fans in the evenings and overnight to expel any excess heat. The excellent results are due to effective design and good insulation in the walls and ceiling, no architects needed. I have in recent years considered adding double glazing to the north facing picture windows, but have so far not found it to be needed.

Great job!!!

What is the name of the insulation external and internal? Looks like a great solution!

what is the name of the insulating panel that looks like concrete? I couldn't understand your accent 😅

Would you be able to kention the Builder who was involved in this project. And also woud love to know more in your future videos about the builders involved in your projects.

❤ Love the idea of moving the house to the back boundary and utilising the front for all the sun and more secure.

wow you made it into our schools investigation booklet we have to watch your video lol

How do the costs compare between timber build and brick built?

Hey mate, thanks for sharing this video. Some great points on the buggest expenses in home buidling. Im curious what the costs would be to engage an experienced designer/architect for a smaller build ~150m2 Ive always been under the impression id be looking around 20-30k for a custom built home

Hey Ben, would you be able to recommend anyone doing similar things to you here in Adelaide? The only company I know is Enduro Builders.

skbidi toilet rizz!! great sigma video

A circular plan has the most floor area for the smallest facade area...that's one of the first things you learn at architecture school

Awesome!

Great video and build - well done! I've been curious about something: Is there an HRV/ERV system that uses two same-size whole house fans, one for intake and one for exhaust, connected to a smart switch? The idea is that on hot summer days, *if* it's cooler outside in the early morning, the smart switch could auto activate the fans to flush the house with cool air, helping it stay cooler throughout the day. Does a system like this exist?

HI, How do you get polished concrete as floor? Do you apply a polish as a finish? What sort of polish?

thanks for your efforts - my dream is to have a very small passive home, when I return to live in Australia - in six to ten years, in regional country NSW. Anthony (Northland, New Zealand - SAT 31 AUG 2024)

thx but other than you ignore island to save, I don't see any other ways to save for passive house (they are all valid for any house). If you can be specific on items it would be better. Most people use standard size cabinet. that's not a point.

On the east side of the house, why didn't you use a roof overhang to prevent summer sun from hitting the glass instead of having to utilize the roller shutters and eliminating all natural light from that side?

what type of insulation is in the walls and ceiling and how many inches? thank you!

How about the thermal mass?

I'm housesitting in a passive house and I asked the owner in advance if we could bring our potable air conditioner for upcoming heat waves. she said she'd rather us not because the house us designed to stay cool. I said "OH, so it actually gets cold in there during a heat wave, without air conditioning" She said she uses a fan and it's pretty cool in Summer. We'll here we are and the house will not go below 24 degrees. It doesn't matter if I set the base temp low, put it on auto or cool setting... the house does not cool itself at all when temperatures are 26 degrees outside. That's not even that hot for a Summer day yet the house has been the same temp inside as it is outside all day. 24 degrees is our night time temp. Meanwhile a healthy room temperature for sleeping (for optimal wellness) is 17-19 degrees. So essentially this passive house can't even get close to a healthy sleeping temp at night when it's not even a heat wave outside. This is pretty weak.

I’m guessing you went against the norm and don’t have a permanently open window for the bathroom.

Great video and I guess she likes you building angle but I don’t see any hot air or stale air tower chimney to evacuate the hot air out of the building. How you control hot and cold air flow in building. I m not an architect but I have interest in passive home. In USA/Mexico boundary they construct dome shaped homes with a small oculus opening at top of dome and temperature difference is 10 Degrees cooler than outside without AC.

lol. We got an air conditioner

2:19 start

How do you screen the French doors? Or are there no flies and bugs left in Perth these days? 🤣😜

Excellent advice! Thankyou. Great work!

We sure got a hot summer this season just gone.

This is excellent information with credentials and experience, thank you. I expect this channel to blow up. 👍 from 🇨🇦 What do you think about subsurface dwellings?

Nice demonstration and explanation. 👍 I had a chuckle at your pronunciation of HRV…I kept hearing HIV. 😅 ❤ from 🇨🇦

Would be useful to discuss humidity and temperature differences inside to outside. Especially how the home performs based upon actual figures in the hottest most humid parts of the year. Passiv House is fundamentally a cold climate system. How Passiv house standards can work for the hot humid parts of Australia is actually the most interesting element. Adding or retaining heat is scientifically easier to achieve than maintaining a healthy inside environment when the outside is so hot and humid and the inside is being warmed/humidified by everything in the house including the humans and pets. A video on this issue along with the numbers would be much appreciated.

Thanks for sharing; I love this style of construction especially when dealing with climate change

Thanks for sharing the insights into your house. It's generated some interesting comments, many of which are worth contemplating. One that jumps out is the facade colour. Our practice (of architects) has been testing this out. We're on the Midnorth Coast of NSW and we put the same house through the NatHERS engine with Shale Grey roof and walls vs Monument roof and walls and the difference was 0.2 star. So negligible. @FrankReif made the comment that ‘walking in front of a dark facade will feel significantly hotter during the day’. I’m not sure about that. Walking next to a white wall that is reflecting the heat back at you is more likely to be uncomfortable. Try being on a Zincalume roof on a sunny winters day and you’ll appreciate the heat reflection. There’s also a big difference between black masonry and black steel interns of how the energy affects the house or those outside it.

I didn't like the way this video was done, as a prospect of a home owner building their house. To call a house passive, you gotta get it certified, so that's northwards of 30k to start with, better to call it Energy efficient home. To make a home owner save money the best you can do is thinking about chopping the middle man off the equation as much as you can. We did it and it was great. best advice? don't make electricians and plumbers to work as if they were passive certified. Spend time on your own, with a check list of things you collect from internet,etc. and insulate the stuff yourself. Buy an expansion foam and silicon for the plumbing work that needs airtightness. And fire rated expansion foam for the electrical part. The roof needs intello membrane kinda product. Best savings. buy a spraygun and paint the house yourself one colour then in the future think about how light flows and decide on feature painting walls. Cabinetry? Create an account in customs and import ready to assemble cabinetry (at the end of the day, lots of middle men do exactly the same).

25° C is ... comfortable !???? That's 77° F - absolutely ABSURD. Meanwhile he's on wife #3 & pays 3 alimonies to keep his AC bill down. 🤣

Interesting design and explanations. Now you have been living there for a while, have you found that the acoustic ceilings gather dust like a fan grill tends to do? This may seem a daft question but as a builder who has also lived in two of my own builds this aspect of dust-gathering (& accessibility to clean grills etc) actually became quite a bugbear for me in my first build and is something I designed out on the second build.

I was interested until he said the some days it gets over the 40s. Here in Erbil, Iraq, 43 is our summer average while it gets to 48 in some days.

25C AC set point! That’s 77F. I’m in TX, I set mine at 22.2C/72F during the day and 20.6C/69F at night.

great video mate, you've done it so well with a selffy stick (im assuming), looks pro....most importantly its great to illustrate to people that PH isn't just for Europe , love it..also what a great job your guys did with the fascia/cappings, its so hard to get that looking flat even after some hot days

Great video, full of very useful, practical info - thank you for posting. Well worth incorporating these features as part of a standard build in hot climates. We used a very similar approach for our house, from design through to construction. Ours isn't a passive house, but is both aesthetic and practical for a tropical climate. Using the right materials and a functional design made a considerable difference to the overall cost and comfort during mid-summer. Total cost AUD$220.0K for a 220m2 home. kzbin.info/www/bejne/mp6WaH9jbtZ6gtU

25 degrees C inside? Crikey mate that's way too warm! I'm a 16 degree guy, though anything below 20 would be ok.

I really liked your description and your style. I would liked to have seen more about the actual design of the house. More on the floor plans. You could perhaps have had shots of the house as you were talking. Only minor points. Overall a very informative video.❤

Love your work!! Any chance you'd want to help on a new build on the Olympic Peninsula?
