Your target level is pretty optimistic, but it is doable. Your air exchange rates will be pretty high.

There is a 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!

Thank you so much! I will check out those threads.

The ambient Co2 where i am is at 400ppm during the day. So i would love to mimic that as close as possible.

I used the ASHRAE formula for Co2 ppm. Here: b3mn dot org/guidelines/archive/version2_1/downloads_v2_1/5IEQ_App-I-2_V2-1.pdf

According to this, if i want 420 ppm, i will need about 550 CFM. Does that sound about right?

Thanks!

ps - yes, i have a Co2 meter
