Hi

I am currently working on a project with a dynamic facade and i want to use thermal simulations to evaluate the optimal states of said facade depending on temperature and solar radiation.

So far i've been working with energyplus through grasshopper and DIVA/Viper for my calculations, but i've only done simulations for static states of the facade.

Now i want to change to a dynamic modeling of the facade, so for example a fixed schedule where i change the geometry used for the shading calculations every 15 minutes or every hour. After reading through the energyplus documentation, i have the feeling, that it's not possible. The only dynamics allowed appear to be being able to change the horizontal angle OR the vertical angle of slats. However, our facade has elements, that can change both horizontal and vertical angles.

Is there a possibility to change the shading geometry during the simulation with energyplus to any state i'd like? Or if not, is there another program, that might be able to do that? If all else fails, how difficult do you think it is to change the source-code of energyplus, to add this feature?

Thanks a lot in advance for any advice!
