The founder of Passivhaus and director of Passivhaus Institute PHI, Dr. Wolfgang Fiest, has just sent word that the Passive House Institute United States (PHIUS) will no longer be able to provide building certifications, and will no longer be considered a partner of the program. While the news comes as a blow to the effort to make inroads for Passive House in the US - a market very much on the radar for super-efficient building standards -- it also reflects the commitment the Passivhaus Institute has to the quality of its certification process.
Wow. More in Inhabitat.
