Is EnergyPlus a prereq to learn OpenStudio
I have been learning OS on my own using the youtube video tutorials but I would like to get up to speed by attending or buying a class online. I have been checking the bigladder and energy-models.com websites and I liked what I saw. I am trying to maximize my time and money but since I am a novice in BEM, I would like a recommendation as to whether I can learn OS if I take an E+ class first. Or if it is just a matter of putting more effort and just take or buy a class for OS only. Thank you kindly!
