Hi! I created my model(Supermarket) using OpenStudio. I created a single zone building with an HVAC system. I'm trying to optimize my building HVAC electricity consumption by changing HVAC setpoints. What I'm doing now is changing HVAC setpoints "by hand" in orther to study the consumption changes, always looking to confort restrictions. As I'm also looking to electricity costs, that are variable during the entire day, I'm trying to find a tool that can give me the setpoints that can minimize energy costs. Do you recomend any tool or any mathematical model that can be useful to this optimization problem? Thank you

This question is unlikely going to produce any good answers in its current form. It is too vague and you haven't explained what you've tried. I suggest revising it and trying to narrow the problem you have.

Check out the calibration example here

In there is a measure that changes setpoints and other HVAC parameters. Calibration is just a subset of Optimization and the OS tools translate between the two very easily.

Thank you for your help BrianLBall. I don't have many experience working with measures. Can you tell me how can I add the measure that you are suggesting to my model? Thank you

The user guide in the spreadsheet repo discusses how to use measures in an analysis context. There are some example spreadsheets to look at as well. Look here for how to use measures in the OS app.
