First US Passive House Retrofit & First California Passive House!

August 25, 2010

The O’Neill residence, retrofitted by Solar-Knights has been certified as the first Passive House in California AND the first Passive House Retrofit in the United States.  This is a wonderful accomplishment!  Be sure to check out their new O’Neill Residence Retrofit Passive House Project page and Photo Gallery on this blog and visit their website.   I am particularly interested in this project since it is a retrofit.  This kind of Passive House project is made more difficult than a new construction project because of dealing with existing construction issues you can not easily change, or may not be financially feasible to change.  Solar-Knights took on this challenge, and from the ACH number of .4 I would say they really did a fabulous job of dealing with the existing conditions.  They will be having an open house of their project in mid October, if anyone would like to see first hand what they have done  (see the contact info on their project page).
