@Vishak yes, you can do this. For any optimization/calibration there are a few steps.
runner.RegisterValue
to measure: Any OpenStudio measure can add runner.registerValue
objets to it, although this is mostly commonly used for reporting measures that are reporting values generated using simulation results. NREL published reporting measures already contain this objets.runner.registerValues
entries as outputs. This is typically done using the Output tab of PAT in algorithmic mode. Some runner.registerValues
are hard coded. If you don't see the one you need, you can add one manually and type the name, but it will only work if it matches a runner.registerValue
generated by the measure.I know steps 4 and 5 are kind of obvious but just wanted to list them as something someone can do to pre-flight check the analysis before kicking it off.
For many users objective functions may come from a single reporting measure. For example on our time series calibration measure it CVRMSE and NMBE might each be objective functions, but there is nothing stopping you from running multiple reporting measures, each adding their own objective functions. In your case I would not add two copies of the time series calibration measure. It was intended to look at load profile throughout the day at hourly or simulation timestep intervals. You second reporting measure should be standard or Enhanced Calibration Report. This uses the Tabular EnergyPlus results which already includes monthly data.
I will say that while it is very easy to have a good monthly CVRMSE and a bad hourly or timestep CVRMSE, the reverse is less common. It would be hard to have a good time series CVRMSE and a bad monthly CVRMSE. So if you have annual data for both, then I don't know how much is added with the monthly objective function. But a common occurrence might be having time series for 3 weeks and monthly for the year. In that case having both sets of objective functions would be critical.
