Hi,

I'm trying to maintain constant the diffuse/direct/global solar radiation for more than 24h. Actually, I can manipulate the weather data, but when I put a constant value to these variables, the output of EnergyPlus takes into consideration the sunrise and sunset. I tried to find the a variable which could help me to not allow the sunrise or sunset, like Azimuth angle, but I think it is implemented directly in the EnergyPlus code.

Do anyone have an idea how can I implement it?

Thank you

You could try locating the building in the Arctic Circle in summer. Would that work?

Yes it works really well! Thank you. (If people use weather files, do not forget to change the location in these files also)

Great. I'll convert it to an answer then.

But there is something not good in this case. Indeed the sun is up for a long while, but the sun turn around my home and the contribution is not the same as if the sun stays in only one part of the building. I would have thought that there would be some option to enable or disable features such as solar radiation.
