Re: [EnergyPlus_Support] weather converter

Have you downloaded V1.2.2?  We now have a "custom format" that can be done 
and should make your job a lot easier.  The CSV input format does expect 
all the usual headers.  I will answer your other questions, inline:

You cannot ignore those records but could put:
Typical/Extreme Periods,0

Your data is every 30 minutes -- so you would put there what your data 
is.  EnergyPlus will interpolate later.

Do not leave field blanks -- assign them missing values as shown in the 
IDDs for weather records in the Auxiliary programs manual.  Or, better, use 
the custom weather format.

You can easily make a CSV file from any of the EPW files with the weather 

Again, I would strongly suggest using the custom format instead.  You 
should be able to save your Excel file as .csv.  (I'm not sure tab 
delimited will work with the weather converter.  Space delimited fields do 
work, however).
