Re: [EnergyPlus_Support] What will the weather file override?

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

Attaching a new weather file only changes/overrides the
site:location parameters.

SizingPeriod:DesignDay are the best indicators if you are doing
autosizing of your building and  you would need to change
them.  Site:GroundTemperature only needs to be used if you have
ground contact from your building surfaces -- ideally you would change
them as well.

Another option would be to use the SizingPeriod:WeatherFileConditionType
along with extreme period designators (SummerExtreme, WinterExtreme) but
this is a bit tenuous as all weather files (though I think most in the
US) might not have a SummerExtreme or WinterExtreme period.

Of course, if you are using Site:Precipitation, you would need to change
that.  Not sure about the pollution factors, construction costs,
tariffs -- those you would have to think about.  And the terrain
field in the Building object -- though you may wish to run all in the
same kind of "terrain".
