Digital Fabrication of a Passive House - Extreme Green Prefab

Last week we completed fabrication of a panelized passive house in Portland. Trucks continue to be loaded and assembly will begin next week.  We are really excited about this project and how it will demonstrate advanced digital fabrication and high-performance.

We have great partners on this project and are very excited to be working with Guido Wimmers PhD, our passive house trainer, staff member of the Canadian Passive House Institute, advisor to the City of Vancouver on the passive house design toolkits, and owner of building evolution.

We are working with an incredible client, Shirra, who is great to work with and who is very interested in demonstrating the benefits of passive house on her own residence.  We are also excited to be working with our builder friends at the Econ Group, Marcel Studer and Michael Dutson.  Last year we collaborated with the econ group on another panelized project in Vancouver (photos here) and we expect to be partners on many more projects in the future.  Check their website and tweets for updates. 

Stefan has been working with this group for months to finalize the Cadwork cad/cam model and manage the fabrication in Portland.  The full photo collection is available on flickr, and some selected images are below.

After all the modeling Stefan generated renderings, three examples below,

Deliveries of lots of wood to the factory.

and a lot of cutting on our Hundegger lines

and some larger "sticks"

and some lots of angle cuts, here are some LVL rim boards
some LSL edge boards for floor panels
some dormer components

it has been very helpful to use the high speed printer heads to mark each piece

the shop has been very busy, with a few very large assemblies being produced by Tony and team.
and assembling all of these components into panels has kept Nate's team very busy
and optimizing the loading of the trucks has taken a lot of work and planning

and now to delivery and assembly at the site.  Check back for more images and videos.
