Htg. Setpoint Based on OAT

edit

Thanks @Ski90Moo for your help. The space heating setpoint is what I am trying to accomplish

There are two ways you could probably do this:

1. Using a spread sheet, create an 8760 schedule of the space heating setpoint based on the weather data (epw file) you are using. Import the 8760 schedule into OpenStudio. Apply the schedule to your thermal zones. You can see how to create an 8760 schedule in this video: https://youtu.be/S_HbjEAGCrg

2. Write a custom EnergyPlus Measure that creates an 8760 schedule based on the epw file selected. That schedule is then applied to the selected zones.
