Hi Douglas,

EnergyPro will model both direct and indirect evaporative cooling. The
inputs for this can be accessed by editing the properties of the HVAC
equipment, either within the model or by creating a new piece of
equipment in the model library. There is a tab marked evaporative
cooling that allows you to input various properties. Don't forget to
set your cooling coil capacity to 0 if you are doing strictly
direct/indirect cooling.
