Re: [EnergyPlus_Support] Re: File - SERVICE

Dear Francisco,

Firstly if you have the Solterm program, you can use the weather files presents in the folder of this content. However if you use the file, be carefully because they donÂ´t gives any value to the pressure or speed wind.
After if pray attention to the document Auxiliary program of E+, look the chapter of weather converter program and learn the title Definitions File & Custom File Processing, there you can see how create "def" input file and in the same folder of weather file with the weather converter you obtained the EPW file to use in E+.

I hope it helped.

Best Regards.

Hello,

I would like to request this service for 2 locations, if that's alright. The locations are:

Name of Location: Aveiro (Portugal)
Latitude: 40.641
Longitude: -8.653
Time Zone: GMT
Elevation: 20m

Name of Location: SetÃºbal (Portugal)
Latitude: 38.527
Longitude: -8.886
Time Zone: GMT
Elevation: 35m

Thank you very much, in advance, for this service!
Francisco O.

PS: I do have some hourly weather data on these places, but it is not in E+ format and i do not know how to deal with it. Will it be of any use for you anyway?
