Re: [EnergyPlus_Support] a room facing North or South- additional
Bojic
i hope you write the all informations under the
Location in your idf file. you can see any example
file in the documentation. these are the latitude,
longitud, time zone, elevation. hence these
information will locate where your buildind locates.
and note that the latitude is positive if the building
is in the norther hemispher, negative if it is in
southern. and longitud is positive if your location is
east of Greenwhich meridian negative if it is west of
meridian. the time zone will be GMT+ your lacal time.
these informations will overide the information given
the weather file.
hope this will help
you
