How can I add precipitation data to an existing weather file? [closed]
Hi everyone, I am studying the performance of a green roof in Opestudio but I have some problems since the weather file I am using to run the simulation doesn't have any precipitation data. I tried to modify the weather file I'm working on but, even if I add rainfall value different from zero in the epw file, it seems like nothing has changed. It seems like, even though I add rainfall data in the epw file, the program still doesn't read them. I tried to modify the epw using excel and also manually, but it doesn't work both ways. I also tried to use elements but I didn't find a column in which I can change the precipitation data. So, basically my question is: Why even though I changed the rainfall data from 999.0 to data the 10 mm/h the software still doesn't read them? How can I correctly add precipitation data to an existing weather file in order to evaluate green roofs performance?
Thanks for your help :)
@alepelu92 this is a duplicate question of this post. Essentially, rain fall amounts in the EPW file are not used. You should use the
Site:Precipitationobject to evaluate your green roof.Thank you so much! Actually I am working with Openstudio instead of EnergyPlus. If I set the precipitation site field in EnergyPlus how can I apply the same ammount of precipitation in Openstudio? I tryed importing the Idf file in Openstudio but it doesn't work.
@alepelu92 sorry that I didn't catch that! I see that you've opened up a new post for this question of applying precipitation in OpenStudio, so I'll keep this one closed.
