Dear Users,
For those of you who usesTYPE15 (for EPW weather data) in TRNSYS 16.
Does TYPE 15 shift the solar radiation to the middle of the hour when interpolation is performed? or uses the weather data by the end of an hour and linearly perform the interpolation?
Thnaks,
Saleh

Subject: Re: Weather Data Reader Type15
Thanks Waseem,
It is not about a specific weather file.
I'm developing my own weather model reader and processor in Simulink. I have used results from E+ to verify my model but seems to be off at some times . So, I used TRNSYS _16, TYPE 15 to determine the solar radiation on south vertical surface using Perez model and compared that to my Simulink and E+ results. I figured that TYPE 15 interpolates the weather file (even at 1 hour time step) and therefore can't use it for verification. I was expecting that TYPE15 will read the weather file without interpolation when time step is 1 hr. Is there a way with this type or others to get the values at the beginning (or end ) of each hour rather than interpolating values at the mid of the hour?
Thanks,
Saleh

Dear saleh saadi,
Salam, Please let me know the weather file name ?
