My hunch is that this is only possible through the Exceptional Design Compliance process, but I just wanted to see if there was a way of doing this within CBECC-Com.
I'm looking to model fixed outdoor air fraction for a system that varies supply airflow (the design OA is greater than the minimum required). My assumption is that CBECC-Com defaults to providing the design outdoor air at all times regardless of the supply airflow rate.
