Re:[EnergyPlus_Support] Window Opening Schedule

["Michael J. Witte" <mjwitte@xxxxxxxx>]

EnergyPlus uses the ASHRAE Clearsky model to generate the solar data for design 
days.  I do not have a citation for this.  It should be described in the ASHRAE 
Handbook of Fundamentals.  

Version 2.1 will also add a new option using the Zhang-Huang model.
