I'm using openstudio plugin 1.5.3 and sketchup 2015 for energy analysis in the building. What I've been trying by far was following up on the manual which had been released by NREL. The problems are , after building the hardware, thermal zones, space types and etc.. through the sketchup 2015 , I can't save those information in the directory which causes impossibility to take the next step to Openstudio 1.5.3, running the simulationand setting up the HVAC and etc.
