[esp-r] Re: Importing weather data

[Georgios Kokogiannakis]

Hi All ,

I recently had a very similar experience as you. I had two epw files that ESP-r could not read with a similar message as yours and similar data trends as those in your photo.

I tried to then use the files in OpenStudio and OpenStudio could not open them either.
We then used DesignBuilder which has what it seems to be a very good weather converter tool and it fixed the files with one click. I think the evaluation version of DesignBuilder will be enough for you if you want to do the same thing or I can convert them for you if you do not have too many files.

Finally, the new epw files were then read fine by both ESP-r  and OpenStudio. The “before” and “after” files are too large to attach them here (4MB in total) but happy to send them to anyone who wants to compare them. The only differences between the two files are in  lines 2 to 8 (header of epw).

Best wishes,
Georgios

Subject: [esp-r] Importing weather data


Hi everyone.



I am trying to install a new weather file, based on DRY13 (Dansk Design Reference Year). I followed ESP-r cookbook 2015, Exercise 3.6, however it is failed. ESP-r said it is illegal. (See the attached JPG)



The new weather data, which I am trying to install is DRY13. I have the excel data, therefore I used softwere called ‘Elements’ to convert it to EPW file. When you create the EPW file, is there order for the weather data comprises?


Venlig Hilsen/Best regards
