OpenStudio-HPXML will always generate an HPXML file called in.xml, located in the run directory.
This file reflects the HPXML input file provided by the user but includes any default values that OpenStudio-HPXML has used.
These default values will all be tagged with the dataSource='software' attribute.
For example, suppose a central air conditioner is described in the HPXML input file like so:
OpenStudio-HPXML will always generate an annual output file called results_annual.csv (or .json or .msgpack), located in the run directory.
The file includes the following sections of output:
Note that all end uses are mutually exclusive – the “Electricity: Heating” end use, for example, excludes energy reported in the “Electricity: Heating Fans/Pumps” end use.
So the sum of all end uses for a given fuel (e.g., sum of all “End Use: Natural Gas: *”) equal the above reported fuel use (e.g., “Fuel Use: Natural Gas: Total”).

For heat pumps with a minimum compressor lockout temperature greater than the heating design temperature (e.g., a dual-fuel heat pump in a cold climate), the compressor will be sized based on heating design loads calculated at the compressor lockout temperature.
This is done to prevent unutilized capacity at temperatures below the compressor lockout temperature.
Any heat pump backup will still be based on heating design loads calculated using the heating design temperature.
Design temperatures are used in the design load calculations for autosizing of HVAC equipment; see HPXML HVAC Sizing Control for how they are derived.
Design temperatures can also be found in the in.xml file.
Design load outputs, used for autosizing of HVAC equipment, are listed below.
Design loads are based on block load ACCA Manual J calculations using HVAC Design Temperatures.
Design loads can also be found in the in.xml file.

OpenStudio-HPXML can optionally generate a timeseries output file.
The timeseries output file is called results_timeseries.csv (or .json or .msgpack) and located in the run directory.
If multiple timeseries frequencies are requested (e.g., hourly and daily), the timeseries output filenames will include the frequency (e.g., run/results_timeseries_daily.csv).
Depending on the outputs requested, the file may include:
Energy use for building total and net (i.e., subtracts any power produced by PV).
Fuel Consumptions
fuels
Energy use for each fuel type (in kBtu for fossil fuels and kWh for electricity).
End Use Consumptions
enduses
Energy use for each end use type (in kBtu for fossil fuels and kWh for electricity).

EnergyPlus Output Variables/Meters
Any user-specified EnergyPlus output variables/meters (e.g., ‘Zone People Occupant Count’, ‘MainsWater:Facility’).
Timeseries outputs can be one of the following frequencies: hourly, daily, monthly, or timestep (i.e., equal to the simulation timestep, which defaults to an hour but can be sub-hourly).
Timestamps in the output use the start-of-period convention unless you have requested the end-of-period timestamp convention.
Additional timestamp columns can be optionally requested that reflect daylight saving time (DST) and/or coordinated universal time (UTC).
Most outputs will be summed over the hour (e.g., energy) but some will be averaged over the hour (e.g., temperatures, airflows).
Note that if the home is not fully conditioned (e.g., a room air conditioner that only meets 30% of the cooling load), the reported zone temperature for the conditioned space will reflect a fully conditioned home due to the way these systems are modeled in EnergyPlus.
OpenStudio-HPXML can optionally generate utility bill output files (annual, monthly, or both).
The annual utility bills output file is called results_bills.csv (or .json or .msgpack) and located in the run directory.
The monthly utility bills output file is called results_bills_monthly.csv (or .json or .msgpack) and located in the run directory.
OpenStudio-HPXML provides an additional output file called results_design_load_details.csv (or .json or .msgpack) that includes details related to the calculation of HVAC design loads for sizing equipment.
The file includes values pertaining to ACCA Form J1 (see example on page 2 of here).
The file is organized into a few different reports described below.
For each HPXML conditioned Zone (see HPXML Zones/Spaces), the following output types are reported.
Only those surfaces attached to a space in the given zone will be included.
For each HPXML Space in a conditioned zone (see HPXML Zones/Spaces), the following output types are reported.
Only those surfaces attached to the given space will be included.
For each HPXML Building (and any HPXML spaces, see HPXML Zones/Spaces), the hourly cooling fenestration load curve (AED curve) from 8am to 8pm is provided.
