Just an observation. I'm glad the presenter spoke first about his choice of creating yet-another-new-term: "upfront". That's the specific reason I watched the video (only to that point). He didn't like embodied because the carbon is not "in" the material? Well, is "upfront" any less obtuse? It's easy enough to clarify the term "embodied" and there is benefit in not adding more words to the lexicon for an already named concept. (I'll grant a pass on rethinking the common name of some fish species to make it more attractive on the menu). I'm all about sufficiency. And "embodied" is sufficient. 🙂

Air sealing does wonders. Ppl got to breathe, ice doesn't. Shows what can be

Another Aussie, I just bought a home that I plan to live in long term, a double brick 1965 house with a good solar orientation in Adelaide. I know it will be my responsibility to remove the gas add solar and make it as efficient as possible. I know We will get days that will eventually pass 50C. You may not be able to predict the stock market but we can predict the climate, invest in somewhere you can escape the heat.

Great video Ken!!

I decided I wanted an earth ship. But without the tires or berm. I do construction usually working on oldest masonry commercial buildings around 150-200 years old. Decided on a skillion/shed roof/mono sloped roof design. Decided on a square notched post and beam timber frame with well insulated cmu block north wall. Glulam some 2x12's or roughly 50x300mm boards to make beams for lofts. Using limestone for masonry veneer. Putting in thermal breaks around windows. I have half my floor area in window area. But zone 5 and yes U.S. climate zones match U.K.'s. Canada does there's backwards. High numbers mean colder instead lower meaning cooler. It's less carbon to use stone and cheaper than have it made into concrete. Concrete block are less labor than stone.

Thanks for this talk. Australia is in a very similar situation to Canada and USA. There is the money to do deep retrofits to Enerphit standard but the govts are not supportive. When we take into consideration those suburbs/ towns that are destroyed by fire /flood/ storms, then paying for climate action and high-standard buildings makes more economic sense. And how much would you pay for a safe shelter for your family? Enerphit might add 10-20% to the renovation cost but the benefits can be huge. Thanks again. Keep up the good fight. 👍

Loving using BEAM! Great tool for early design decisions on materials selection.

great presentation! Can't wait to see the embodied carbon standards that come out of this.

Amazing presentation 👏 Nice work Chris!

$95 a cubic ft? I hope he meant to say cubic yard.

Curious to know if this can be broke down even more for paver base?

I 95 repair project brought me here. Answered all my questions. Thank you.

Does the PHN have any affiliates or partners in Texas. I have a passive home project in the concept phase and looking to build a team that knows the state and programs.

Great fact-filled presentation! I took several screen shots. ENERGY STAR certification is a prerequisite for DOE ZERH, so if someone gets the higher tax credit for ZERH, it would be weird if they also got to take the lower tax credit for ESTAR.

Could there be links to a wiki of the slide show with data updated as it comes?

Can anyone recommend any more learning videos on projects like "The Battery"?

This is a disgusting video. You use DEI to hide your own racism. It's not diversity or inclusion if you will only hire black owners or mbe's. Sorry, you're not a victim.

Plant a tree instead

very nice

How come this isn't in the south? Specifically Florida?

This sounds like a far better approach than the more fixed BREEAM assessing process and dreaded BRE audit.

Michael's remarks start at 9:39

the video was quite informative but the tone was a little patronizing

is there a reason why the first house in Colorado decided to push the windows closer to the outside, thereby increasing the risk of condensation on the windows?

I am very intrrsted in this but I am in thailand and there seems no experts on this here 😢

this presentation was pretty bad. Just shows off many expensive windows that are shipped half way around the world and they only have an R value of maybe 8 or R10 max!! Why not just use regular cheap windows and with the 80% savings then buy or cusotm make some thermal shutters to cover the windows at night to an R value closer to R15. Glass is a horrible insulator, Best to have cheaper alternative materials bring up the Rvalue.

Great webinar!

Question: Does owning a dog that you let in and out of the house during the day totally screw up your Passivhaus performance? I’m being serious.

Thank you for the (objective) comprehensive presentation. Where else is interior Thermal MASS,? other than , floor slab[= lower priority], as compared to wall-mass. As we all know Dry-wall is not MASS. What maybe the ratio of true MASS, and floor space, as compared to 'Aperture =over all window-opening.? How many trees had to be scarified to build this house - what was percentage of waste building this in reg. Stick-Frame.? What was the actual cost per sq/ft., and who can afford this?. If this is a truly Direct Passive Solar home, will it NEVER go below 38 degrees when ALL other systems are down [as there are 'Active components], when there is no external heat source, while outside there's a raging winter storm - 3 days in,, and temps are hovering around 0 F. and lower?! Will it never freeze inside, no matter what conditions.? Are there in interior walls -- upper and lower vents to cause natural convection through out the house, thus moving [warm] air w/o mechanical means? Are your windows on Solar south simply 'clear-glass, except on some East - West, but North side indeed have Low-E glass?. ( or other) How easily could you change out windows, and doors?, or are they all locked in. Thanks for the discussion on these points.Paul Kloppenburg / pckpablo@gmail.com -- Crestone, Colorado

This was a great presentation and our first commissioning the UL Zehnder flex duct; which to our surprise performed very well! I really enjoyed how Greg talks about siting the house and active modeling to ensure Passive House certification.

do you have any suggested window manufacturer who satisfies these values who are also having hurricane rated glass

Amazing stuff. Thanks so much for this!

Haha wow. How did I miss this upload?!

Awesome content! You need more subs! You should use Smzeus . c o m, I’ve been using it on my main channel to promote my videos.

I couldn’t take the sound, its pre-echoing, post-echoing , squelching, i dunno what the term is but i auit after less then 30 seconds because of it. Please edit the audio somehow!

Good!

Thank you, to all the students. Let's be clear: it is "Part of the solution" - there need to be more contributions like that. Lower emissions in traffic, healthier food, less waste, ... And it's our choice, to start imporving in all these areas. The existing examples (special thanks to ChoShelds Studio and many other committed architects) prove, that this is really working; it's not expensive and it also improves the quality of live (think about the smoke from wildfires 2020). These are positive developments - let's unite for a vision of the future which will improve living conditions.

Great job!!! Go Stuyvesant!

Love this project!

Johnny here - I would certainly be remiss if I did not mention here: if you like this presentation make sure to subscribe to NAPHN's channel as well as our for more great information about Passive House and High Performance Building!

positive ! ;-)

I am planning to build an Active Adult 55+ community with a community center for South Asian community in Ontario near Toronto. Looking for a nice piece of land approximately 50 Acer for first phase. This will show what can be done and its achievable if done on mass SCALE. Looking for ACTIVE investors and professionals to join the mission.

There are more women leaders in Passive House than most design and construction communities! Go Tessa!
