Ya I get it, but finding too many issues with sip or Zip system sheathing, from dimpling, sagging to water getting in behind OSB and inside walls...foam is out, not sustainable, etc etc etc...nice try though!

Um … didn’t the Canadians and the New Zealanders get into awful trouble twenty years ago when they built with foam outside of OSB? Water got in, the OSB rotted, and many, many houses had to be demolished. At the very least, you need to use a special foam with grooves or depressions in it, to allow water to flow downwards if it does get in.

The system is great. I developed my own version of this a few years ago and have prefabricated two houses with great success. The next step is not only to have windows and doors installed but also the cladding. We have moved to this stage in development and will be constructing a Passivhaus in this manner. If anyone is interested I can follow up with development problems and hopefully successes.

Interesting although it does seem to resemble some other systems around. Wondering if the stud part anchors to the concrete part of the foundation with the foam panel "hanging" off the studs wall system, or does the foam panel also need to rest on the concrete foundation? If the prefab footing shown is used, it appears that the panel could rest on the foam and perhaps the foam could carry just the load of the panels at least for a couple of stories.

I love the idea of an airtight building. Maybe I'm being silly here but if questions are not asked then one will never know! However I have a question about how airtight a building should truly be when it comes to high winds. If a building is so air tight living in a windy to almost tornadic to downright tornadic weather would the structure be more capable of imploding than a typical structure that was not so airtight?

Congrats to my bro-in-law Tim
Congrats to my bro-in-law Tim McDonald for capturing the attention of Energy Vanguard!

I wonder about the EPS insulated concrete form pictured above…does it have the necessary bearing / compressive strength to be positioned under the perimeter of a monolithic footing?

Compared to building a “pretty good house” I continue to wonder at the economics of Passive Houses; Tim and I will again debate that subject over a few beers after we journey to Philly for the week after Christmas.

Allison I want to thank you
Allison I want to thank you for featuring advanced systems, but our company – at http://www.eco-panels.com – was 10 years ahead of this system. And we do not use polystyrene foam like this company uses that the National Institutes of Health has encouraged us to remove from building systems. This was noted in the 12th Report on Carcinogens issued by the National Toxicology Review. We only use closed cell polyurethane foam – VOC and formaldehyde free that is both structurally stronger and much more efficient at insulating. I hope you will post this comment.

Kris, the panels I saw in Philly had framing with 24" o.c. See the photo above of the workers putting the panel in place (third from the bottom).
