Re: [EnergyPlus_Support] Defining DesignDays based on the weather file

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

Succintly put:  Weather files, even with extreme
conditions, are still TYPICAL WEATHER FILES/DATA.  TYPICAL is what
you want for Energy Simulations.  

Design conditions from ASHRAE represent longer term period of records and
will more accurately depict the .4%, 1%, 5% etc tail of the
conditions.   If you are sizing equipment, you want
these.  If you are not sizing equipment -- it doesn't matter so
much.
