Building science pays off for the Proud Green Home at Serenbe (Video)

Architect Chris Laumer Giddens gives us a behind-the-scene look at how the Proud Green Home at Serenbe achieves high performance.

As part of the process for EarthCraft certification, the Proud Green Home underwent a blower door test and score about 90 percent tighter than a home built to standard codes.

On his blog, Chris gives us some insight into the building science: 

How did we do it? 

We have been posting videos on the construction of the PGH, showing some of the air sealing techniques, including using flashing tape at all joints between framing members, installing BASF open-cell spray foam in all the wall and roof cavities, and using ZIP System R Sheathing on the walls and their Roof Sheathing on the roof. We’ve also talked about the building envelope construction including the foundation and above grade walls. All of these best practices and products resulted in a pretty tight structure.

Designing a home is about architecture and building science. It’s about the house as a system, where everything affects everything. For two separate Georgia homes, and for two separate builders, we have designed homes that have achieved below 1.0 ach50. The first one, the Grant Park Residence, tested at 0.77 ach50 at the final inspection for ENERGY STAR Certification. We also designed a third Georgia home that achieved less than 3.0 ach50, without the use of spray foam or ZIP System.

We’re currently working on projects now where the homeowners are interested in the same (or better) performance so they can have low energy consumption, increased comfort and indoor air quality, and long term durability.

Here builder Luis Imery of The Imergy Group shows us the open cell spray foam insulation from BASF and other building techniques.
