If you really want to have one solar radiation condition and one OD temperature for the whole year day and night, run the DesignDay simulation once and pick up the result for the sun position you want and repeat it 365 days on a spread sheet.
May be you are driving a mobile home or an airplane following the sun.
The arctic sun radiation still varies during the 24 hr period.

change your location to one where the sun is above the horizon at all times.

So is there a way to modify EnergyPlus to change the hours that it thinks the sun is up?
Thanks.

- You can, of course, have a hand manipulation that would put the values in.
- However, even if you do that, EnergyPlus will ignore all radiation when the sun is down.

- 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?
