Thanks, but i looked into plants, and they dont really lower Co2 any meaningful amount. See page 2 here: sweets.construction dot com/swts_content_files/152845/713268.pdf
I agree that the ASHRAE levels are way too high. I was more using that paper to figure out what CFM i need in an HRV/ERV unit, for a given Co2 ppm target.
Just curious - why wont they sell that HRV into the US? (not that i could use it anyway as it is an 'in-wall' unit)
Thanks
