Cash House Receives Passive House Certification

12.21.12 by the Green Hammer Team

We're excited to announce that our Cash Passive House project received its international Passive House certification from the Passive House Academy. The Cash Passive House is now the first Passive House building (in at least the Pacific Northwest) to be certified by the International Passive House Institute out of Darmstadt Germany. Other buildings have been certified by Passive House U.S (PHIUS) in the region (including some of ours), but this is the first attempt at collaboration with the international certification body in the region and we are happy to report the results!

Ultimately both the International and the U.S. versions of the Passive House standard are in general terms the same, however, as strong ambassadors for the standard we are interested in promoting all national and international certifying bodies. Stay posted as more pending Green Hammer certifications are announced by PHIUS and the International Passive House Institute, including the groundbreaking Capaces Leadership Institute.
