Re: [EnergyPlus_Support] Re: Role and Precedence of EPW Header information

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

Weather files are discussed in quite a bit of detail in the
Auxiliary Programs document.

Primary information from the weather file headers is the location data --
which, if a weather file is available to the run, overrides any
Site:Location data.  (In fact, you don't then need a Site:Location
object).

Not sure why your sizing:zone run fails.  There are many example
files with and without weather files that don't fail.  

For your weather file that appears to be in Baltimore - you either need
to make it be in that time zone or sync your schedules to the GMT time
zone.  Location is used to determine sun position -- as you've seen,
it is not embedded anywhere in the weather files
