Component Loads ``componentloads`` Heating and cooling loads (in kBtu) disaggregated by component (e.g., Walls, Windows, Infiltration, Ducts, etc.). Unmet Hours ``unmethours`` Heating and cooling unmet hours. Zone Temperatures ``temperatures`` Zone temperatures (in deg-F) for each space (e.g., conditioned space, attic, garage, basement, crawlspace, etc.) plus heating/cooling setpoints. Zone Conditions ``conditions`` Zone conditions (humidity ratio and relative humidity and dewpoint, radiant, and operative temperatures) Airflows ``airflows`` Airflow rates (in cfm) for infiltration, mechanical ventilation, natural ventilation, and whole house fans. Weather ``weather`` Weather file data including outdoor temperatures, relative humidity, wind speed, and solar. ======================= =================== ================================================================================================================================================ .. [#] This is the argument provided to ``energy_rating_index.rb`` as described in the :ref:`running` usage instructions. Timeseries outputs can be one of the following frequencies: hourly, daily, or monthly. Timestamps in the output use the start-of-period convention. Most outputs will be summed over the hour (e.g., energy) but some will be averaged over the hour (e.g., temperatures, airflows). .. _home_configurations_hpxml: Home Configurations (HPXML) --------------------------- Based on which calculations were requested in the HPXML file, home configuration details in HPXML format will be found in the ``results`` directory for each simulated home. The HPXML files will have the same filename as the :ref:`home_annual_outputs_csv` output files, but with a .xml extension instead of .csv. The files reflect the configuration of the home after applying, e.g., the ERI 301 ruleset. The files will also show HPXML default values that are applied as part of modeling the home. Defaults will be applied for a few different reasons: #. Optional ERI inputs aren't provided (e.g., ventilation rate for a vented attic, SHR for an air conditioner, etc.) #. Modeling assumptions (e.g., 1 hour timestep, Jan 1 - Dec 31 run period, appliance schedules, etc.) #. HVAC sizing calculations (e.g., autosized HVAC capacities and airflow rates, heating/cooling design temperatures and loads) Any defaulted values will include the ``dataSource='software'`` attribute in the HPXML file. .. _home_energyplus_files: Home EnergyPlus Files --------------------- In addition, raw EnergyPlus simulation input/output files are available for each simulation (e.g., ``RatedHome``, ``ReferenceHome``, etc. directories). .. warning:: It is highly discouraged for software tools to read the raw EnergyPlus output files. The EnergyPlus input/output files are made available for inspection, but the outputs for certain situations can be misleading if one does not know how the model was created. If there are additional outputs of interest that are not available in the annual/timeseries output files, please send us a request. .. _bill_outputs: Home Utility Bills (CSV) ------------------------ OpenStudio-ERI can optionally generate annual/monthly utility bill output files (e.g., ``RatedHome_AnnualBills.csv`` and ``RatedHome_MonthlyBills.csv`` for the Rated Home). **Note**: These output files are only available when utility bill scenarios are specified. When no utility bill scenarios are specified, utility bill output files are not generated. See :ref:`hpxml_utility_bill_scenarios` for more information about specifying utility bill scenarios. Annual Bills by Fuel Use ~~~~~~~~~~~~~~~~~~~~~~~~ Annual results for each utility bill scenario defined in the HPXML file are listed as shown below. ================================================= ==================== Type Notes ================================================= ==================== : Total (USD) Scenario annual total charges. : Electricity: Fixed (USD) Scenario annual fixed charges for electricity. : Electricity: Energy (USD) Scenario annual energy charges for electricity. : Electricity: PV Credit (USD) Scenario annual production credit (negative value) for PV. : Electricity: Total (USD) Scenario annual total charges for electricity. : Natural Gas: Fixed (USD) Scenario annual fixed charges for natural gas. : Natural Gas: Energy (USD) Scenario annual energy charges for natural gas. : Natural Gas: Total (USD) Scenario annual total charges for natural gas. : Fuel Oil: Fixed (USD) Scenario annual fixed charges for fuel oil. : Fuel Oil: Energy (USD) Scenario annual energy charges for fuel oil. : Fuel Oil: Total (USD) Scenario annual total charges for fuel oil. : Propane: Fixed (USD) Scenario annual fixed charges for propane. : Propane: Energy (USD) Scenario annual energy charges for propane. : Propane: Total (USD) Scenario annual total charges for propane. : Wood Cord: Fixed (USD) Scenario annual fixed charges for wood cord. : Wood Cord: Energy (USD) Scenario annual energy charges for wood cord. : Wood Cord: Total (USD) Scenario annual total charges for wood cord. : Wood Pellets: Fixed (USD) Scenario annual fixed charges for wood pellets. : Wood Pellets: Energy (USD) Scenario annual energy charges for wood pellets. : Wood Pellets: Total (USD) Scenario annual total charges for wood pellets. : Coal: Fixed (USD) Not used by OS-ERI : Coal: Energy (USD) Not used by OS-ERI : Coal: Total (USD) Not used by OS-ERI ================================================= ==================== Monthly Bills by Fuel Use ~~~~~~~~~~~~~~~~~~~~~~~~~ Monthly results for each utility bill scenario defined in the HPXML file are listed as rows corresponding to Month, and columns corresponding to Type. .. _hers_diagnostic_output: HERS Diagnostic Output ---------------------- A HERS diagnostic output file (``ERI_/results/HERS_Diagnostic.json``) can be produced if the ``--output-diagnostic`` commandline argument is used; see the :ref:`running` section. The output file includes hourly data and is formatted per the `HERS Diagnostic Output Schema `_.
