RE: [EnergyPlus_Support] which items is useful in weather data for hvac ?

["Crawley, Drury" <Drury.Crawley@xxxxxxxxxx>]

This is explained in the Auxiliary Programs documentation--where the EPW
format is described.  It tells you which fields (currently) are used by
EnergyPlus--beginning on page 14.  Note that we are working on an update
to the EPW format which will now also include precipitation amounts and
rates--for use in moisture modeling.

Subject: [EnergyPlus_Support] which items is useful in weather data for
hvac ?



Dear Energy Plus Team: 
In epw file, there are 26 items. It is difficult to fill each items 
without error. In fact no all items be used for HVAC simulation 
calculation , such as "Global Horizontal Radiation {Wh/m2}". Some items 
have correlation each other , such as "Dew Point Temperature {C}" 
and "Relative Humidity {%}". 
Which items will be used for cooling/heating load calculation ? For 
hvac energy consumption calculation ? For lighting energy consumption 
calculation ?
Regards
Lei Fei
