Hi, I have downloaded some residential and commercial benchmark idf files. I was wondering if I can open them through openstudio directly? Or should I open them using EP-launch (although the EP-launch that came with the openstudio/energyplus folder gives an error and does not run - so in this case, should I install stand alone energyplus?) This is my first time using OS, and I havn't used Eplus in many years. Is there anything equivalent in OS like eQuest wizard to get up and running super quickly, and worry about the details later? Appreciate any pointers. -Rohini
