Hello P, here are some other steps I have taken previously to reduce simulation time. Not certain which ones would be applicable to your simulation so I suggest doing some testing to confirm that the result you want doesn't change appreciably when you attempt to reduce simulation time. I'd alo suggest thinking about how accurate you need the model to be before attempting to reduce simulation time. Good luck! -N

Under the simulations tab (blue arrow) you can:

1. reduce the number of timesteps per hour (red arrow)
2. reduce the run range (green arrow); perhaps just run a selection of days/weeks during each season C:\fakepath\Menubar_and_Untitled.jpg

Other possibilities:

1. don't run simulation over the entire year (red arrow) and only run for sizing days (green arrow)
2. take the sized HVAC parameters, input them into your model (i.e. hard-size everything), and then turn OFF sizing days (green arrow)
3. change the solar calculation type to "minimal shadowing" (orange arrow); check here to see if this assumption makes sense C:\fakepath\Untitled.jpg
