Hello everyone,

I have been trying to make an air loop in OpenStudio with several zones and a standard of 10 air changes, where the recirculation rate is max 50%. So basically I would like a minimum of 5 fresh air changes and a total supply air flow of 10 air changes. I can not figure out how to do this, I have tried setting the outdoor air flow air changes per hour to 5 and the design supply air flow rate to the double of that amount, but almost no air is recirculated when I run the simulation. Does anybody have recommendations?

Regards, Mathijs
