Thanks!

Do you actually have a CO2 measuring device?
I
built a CO2 detecting HRV controller, and I know what CO2 levels actually look like in an urban environment.
Your target level is pretty optimistic, but it is doable. Your air exchange rates will be pretty high.
There is a
DIY HRV thread that features lots of brave and creative HRVs that could be window adapted.
Wishing you success with your project, and
take loads of photos!
Best Luck,
