Re: [EnergyPlus_Support] Cool Tower & Roof Spray

An appropriate modeling strategy for the cool tower would be to
use a direct evap air system and then decrement out the associated fan
energy.  IF the air flow rates match reasonably well, I think it should
work okay.  But I haven't tried it.  

No ideas on the roof spray, it is way too complicated.
