Hi, I'm new to EnergyPlus and BEM, and I am hoping to use EP for assessing potential building/home energy upgrades. I guess that OpenStudio (with OpenStudio Application) can do alot more than EP-Launch 3. I will probably spend a lot of time learning how to use one or the other and I'm trying to figure out which to focus on. I'd be very grateful for any guidance. Kind regards, Paul
