Re: [EnergyPlus_Support] Weather data : convert csv into epw



Do a conversion from EPW to CSV with the Weather E+ tool, then use this as the example format for your CSV.  Be sure only that all the commas and return characters are the same.

Hello,

I'm trying for two days to convert hourly weather data from csv to epw (for Basse Terre, Guadeloupe, West Indies).

I used for month the "Weather Manager" from Ecotect and now I realized that he had a problem converting solar radiation data and I no more confident with this software.

So I tried to use the "Weather" soft delivered with E+.
What is the csv format expected ?

I found this :
" Note on the input CSV format : it is the epw csv format. The CSV format must mirror the output CSV format very closely. The processor espects a location header records and the headers for the data fiels as a minimum"

What does it mean ?
I took headers for the epw file and it don't work.
Does I have to take the headers from the*.rdd file ?
Which values are essentials to create a full epw file ?

Can I have an csv example file to help me understand ?
How can I create my epw file ?

I can send my csv file if it can help.

I precise that I'm really familiar with this kind of problem : that's in Wh/m² and not in J/cm², real csv with "," and no ";", etc....

Thanks a lot
Have a nice day

Vincent Priori
