An update on the NIST Net Zero Energy Residential Test Facility (NZERTF). Last week, we completed all groundworks below the slab, including the installation of the XPS insulation and hydronic tubing. On Tuesday June 14th, the basement slab was poured, and backfill against the foundation was started.
Looking forward to next week, we expect to take delivery of the first floor framing package from Foremost Industies. The uniqueness of this project dictates that the entire framing package comes to the site 100% precut and labeled, meaning the framers simply have to nail the pieces together. In theory, this approach will ensure tighter quality control and speed the framing process, while reducing construction waste.
Several people have commented on how this precut framing package is a technique that has never been used before. Not true. In fact, starting 100 years ago, Sears Roebuck sold tens of thousands of homes via mail order using this same method. Many were bungalows. Interesting how the old becomes new again.
Photos of the project can be seen on NIST's Flickr site.
