Comments on climate-specific standards study now open

In cooperation with Building Science Corporation, under a U.S. DOE Building America Grant, the PHIUS Technical Committee has completed exhaustive research and testing toward new passive house standards that take into account a broad range of climate conditions and other variables in North American climate zones and markets.

This report contains findings that will be adapted for use as the basis for implementing climate-specific standards in the PHIUS+ project certification program in early 2015. Furthermore, as materials, markets and – climates – change, the PHIUS Technical Committee will periodically review and adapt the standard to reflect those changes.

  1. Hi Katrin,

    I am a Building Science Graduate Student from Ryerson University, Toronto, Canada. I am currently writing a research paper on ERV performance rating standards. I have read the Climate-Specific Passive Building Standards draft and I am interested in PHIUS’ proposal on the adjustments to HVI and AHRI ratings. The draft mentioned this is being written up separately. Do you have any idea where/how I can access PHIUS’ proposal on the efficiency ratings? Much thanks.
