Hi, everyone! So it appears to me that my energy modelling software does not allow for modelling unbalanced airflow in a space (i.e. exhaust rate is higher than supply or vice versa). What are some workarounds people use to account for energy use in unbalanced airflow situations? I imagine one can model a system with a correct supply airflow and account for additional (or reduced) exhaust rate later in exceptional calculations. Can someone describe this in more detail? My main interest is energy modelling as per 90.1 for LEED. I use DesignBuilder but I am mostly interested in a universal solution.
