Hello @devang @chris
As per suggestions and above discussion i modelled the mixed mode schedule for windows and Ac. To check the whole workflow i visualised the natural ventilation energy output and cooling load profile output on 3d chart. It seemed fine. But when i checked the unmet hours values it seems crazy. Can you please have a look on the attached modified file. Just to make clear what i wanted to achieve is that to switch on ac for a specified set of month (mid March to mid June with windows closed) and naturally ventilate for rest of the year (Typical type of usage schedule for ac in this composite climate). I have reattached the file.
