I used the below code to apply pre-cooling strategy to the model. The results showed about 60% reduction on the heating consumption and 68% increase in cooling. Can you explain the logic behind the reduction in heating?

@ShaymaaSK can you also show the schedule definition for the baseline thermostats? Or better yet, provide links to both full IDFs using Google Drive, Dropbox, etc. for others to review differences for all inputs?

Dear Aaron, Please find below the link to IDF https://drive.google.com/file/d/1Jcv_...

@ShaymaaSK thank you. It looks like that link is only for the precooling IDF with your cooling setpoint schedule above. Can you also add a link to the baseline IDF with the original cooling setpoint schedule? That way others can compare inputs to explain the changes in heating & cooling.
