We have an issue with the Honeybee_Generate Cumulative Sky component using different TMY-Datasets.
If we use the IWEC EPW from DOE site, the generated sky looks good and the difference between the east-west irradiation seems ok.
So, it seems there is a general issue using GenCumulativeSky.exe TMY/TMYx datasets. Has anyone experienced the same issue and can help me out? Is there a detailed documentation of GenCumulativeSky.exe that we can look into in order to figure out what’s the problem with the calculation?
Thanks a lot.
