Re: [EnergyPlus_Support] present weather codes

hi,

Firstly, thank you for the answer.

I have seen the respective documentation. The table "weather codes field interpretation" explain 9 different numbers range from 0 to 9. However, this part of the documentation refers to the epw format. The next paragraph in the same document is the epw csv format. If you read the data records (CSV) on the page 53 of auxiliary energy plus programs, you will see that the value which is given for the present weather codes is C9C9C9C9*0?9?9?9?9?9?9?9*0C8C8C8C8*0*0E8*0*0 and not a string of 9 numbers.

If I had a string of 9 different numbers, I would not have a problem to expain this information. Is this an effect of the weatherconverter program?

They should be documented in the definition of the weather file format (just before the Weather converter in the Auxiliary Programs guide).

Energyplus doesn't use them--they are maintained from source data.

Hello everyone,

In order to create a weather file, I read the weather converter program. I chose to create a csv file and then I used the weatherconverter program to create the epw file. I see that one of the weather file fields is the present weather codes. Could anyone give an explanation to the following information:

      C9C9C9C9*0?9?9?9?9?9?9?9*0C8C8C8C8*0*0E8*0*0

Thanks in advance,
George
