I'm trying to create a custom weather file with a constant radiation value 24-hours a day. I have modified the .CSV file accordingly, but when I use Weatherconverter to create an .EPW file the radiation is only applied during daylight hours (as seen in my output report after running a simulation).
Is there a way to override this? How about an easy way to directly modify an .EPW file without using the Weatherconverter utility?
