It seems that Clark & Tim, the guys who wrote Building Green, moved in the Passivhaus direction. They have a project called Nauhaus where they are attempting to bring together their past experiences with the Passivhaus standards.
I believe, as I have written before, that the Passivhaus standard is not a practical nor sustainable form of construction – though there are some excellent and applicable ideas and inspiration to be drawn from it. The Nauhaus was built with hemp, which from the theoretical (at this point) knowledge I have gathered simplifies, ecologizes and reduces costs of many construction aspects. Yet because of Passivhaus standards Nauhaus also reintroduces many complications which I find … uninspiring. Just this morning I was reading their chapter on building a green roof, then I came across the massive, industrial insulated crane-lifted panels they used in the Nauhaus project. Though I can appreciate their efforts to move forward and improve … it feels to me like they took a wrong turn somewhere … I think Passivhaus had something to do with it.
I was surprised to see in some of the images the Tradical procucts and then to learn that the interview I posted with Ian Pritchett was actually from the Nauhaus project.
Amongst the information on their website is an educational set of posts with images showing the contruction chronology – from foundations to a completed building. At this point in my education, these documented processes are extremely useful and rewarding. The chronology starts at the end of this page – from where you can scroll up and forward in time to see the project progress.
My main take from these images is on some thoughtful tricks on how to efficiently prepare and install formwork for the hempcrete as you can see here and here:
And also this super-simple ingenious carpentry lesson from Tim – as he creates a simple tool for measuring and placement of formwork from here.
