I might have one - not sure. I had not heard of Passivhaus when I altered the design of a house I like and turned it into a strawbale house with plaster inside (Structolite) and cement stucco on the exterior. We don't have air exchange, but we do not need air conditioning and do well with minimal heating in the winter if it is sunny. The key, as you have said many times, is building tight, minimal air leaks, and lots of insulation. It works.
Our bedroom with two humans and a dog gets to about 800 ppm CO2 at night. Fresh air is delivered directly to the bedroom, which is my standard design practice. The house isn't a Passive House, but it's superinsulated and is airtight (~0.03 CFM50 per sf of enclosure) so it's quiet too.
I slept in the first certified PH in North America in 2006, in Bemidji MN, for the first North American PH Conference (about two dozen of us.) Please do note that North Americans were building superinsulated airtight buildings with heat/energy recovery long before PH!
