Hello all, quick question regarding extreme environments.

If the .EPW format was to include extreme environment parameters such as Mars or the Moon, with very low pressure and almost no humidity, do you think Open Studio could include new ways of calculating solar radiation and heat gain on other celestial bodies ? I have a master in Space Architecture from the University of Houston and I mainly work with Rhino and Ladybug components in Grasshopper.

Let me know if I can help, (C+ and HTML code experience)

This isn't the first time this has been asked, but no, EnergyPlus, the simulation engine for OpenStudio isn't suitable for simulations in space, the moon, or on non-Earth planets. Someone may be able to provide some suggestions in an answer. For reference, there has been enhancements for use on Earth in ships including water heat transfer, and in past has been used for trucks, sorry won't help you on Mars.

Hello and thank you for the anwser, I also posted on https://github.com/NREL/EnergyPlus/, here's their answer :"I've actually had thoughts about this and plan to investigate things like this. The problem is that the EPW change alone would not even close to sufficiently affect the simulation results to make them accurate in other planet conditions. There will need to be drastic changes to the physics calculations, modifications to solar calculations, the meaning of a "day"" So it would need a couple of people to create new code and new calculations to accomplish that but it's not impossible.

@T.lagarde can you share a link to the Github issue or post that you made? That would be helpful for others who are interested.
