Todd,

You can tell eQUEST to run multiple Design Days by setting the start day and
the number of days in the Design Day Properties dialog box in the detailed
interface (don't know about the wizard). For example I normally set the
start day to 6/1 and the number of days to 120. That way it will cover all
the solar angles from June - September combined with the ASHRAE Cooling DB /
WB, and will use the heating/cooling design day schedules specified in the
Week Schedules. I figure this should pretty much cover it, although as Carol
said there is usually a peak in the weather file that exceeds the ASHRAE
conditions.
