************* Beginning Zone Sizing Calculations
** Warning ** SizingPeriod:DesignDay: AHMEDABAD:1.0% WINTER
** ~~~ ** Humidity Indicator Temperature at Max Temp=12.8 > Max DryBulb=12.2
** ~~~ ** Humidity Indicating Type=WETBULB
** ~~~ ** Conditions for day will be set to Relative Humidity = 100%
** Warning ** Zone areas*inside surface emissivities are summing to zero, for Zone="Z1"
** ~~~ ** As a result, MRT will be set to MAT for that zone
************* Beginning System Sizing Calculations
** Warning ** Could not find chilled water coil with name SYSFANPWRVAV_SYS 1 COOLING COIL on any plant loop
