Revision history [back]

Hi,

Background: I am using OpenStudio v2.9.0 and EnergyPlus v9.2. I am modelling aggregate residential housing stock using NREL's ResStock v2.2.4.

I am currently trying to determine the number of heads (ie the number of indoor units) for ductless minisplit heat pump modelling, as this affects initial capital cost. In the parametric analysis tool, my input is typically Apply Upgrade = HVAC System Heat Pump|MSHP, SEER 15, 8.5 HSPF to specify a change from a propane furnace + AC baseline building to a building with a SEER 15 MSHP. Nowhere in the PAT GUI do I specify the number of indoor units, so I am assuming that ResStock and PAT are automatically choosing the number of units based off of a default algorithm that takes into account number of rooms, number of living and conditioned spaces, etc.

Is there anywhere in the ResStock output (ie the building characteristics JSON file, the E+ output file, the simulation log file, the results.csv file, or the annual timeseries file (which I save as a pickled dataframe) where I could find the integer number of indoor units for a MSHP simulation?

Thanks!
