Openstudio components

edit

I'm new on using openstudio, I've constructed my model but I need some help to check it out as a whole .

I've attempted to model an electric fan for cooling and an electric heater for heating but it didn't go well. (I've found components for those two on BCL but I have no idea how to import them in my model since what I downloaded from the website only contains an (.xml) files \ and these components doesn't appear on integrated BCL tool in openstudio App .

Also I wanted to figure out how to control operable windows schedule. (I've used the fixed interval schedule measure for all my other specified schedules )
