pre-releases)](https://img.shields.io/github/v/release/NREL/OpenStudio-ERI?include_prereleases)](https://github.com/NREL/OpenStudio-ERI/releases)\n[![ci](https://github.com/NREL/OpenStudio-ERI/actions/workflows/config.yml/badge.svg?branch=master)](https://github.com/NREL/OpenStudio-ERI/actions/workflows/config.yml)\n[![Documentation Status](https://readthedocs.org/projects/openstudio-eri/badge/?version=latest)](https://openstudio-eri.readthedocs.io/en/latest/?badge=latest)\n\n\nThe OpenStudio-ERI project allows calculating an Energy Rating Index (ERI) using the Department of Energy's [EnergyPlus™](https://energyplus.net/) simulation platform.\nThe building description is provided in an [HPXML file](https://hpxml.nrel.gov/) format.\nOpenStudio-ERI is intended to be used by user interfaces or other automated software workflows that automatically produce the HPXML file.\n\nThe project supports:\n- ANSI/RESNET/ICC 301© Standard for the Calculation and Labeling of the Energy Performance of Dwelling and Sleeping Units using an Energy Rating Index\n- ENERGY STAR Certification System for Homes and Apartments Using an ERI Compliance Path\n- IECC ERI Compliance Alternative (Section R406)\n- DOE ZERH Certification Using an ERI Compliance Path\n\nFor more information on running simulations, generating HPXML files, etc., please visit the [documentation](https://openstudio-eri.readthedocs.io/en/latest).\n\nOpenStudio-ERI uses [OpenStudio-HPXML](https://github.com/NREL/OpenStudio-HPXML) to run the individual EnergyPlus simulations.\nA high-level workflow diagram is shown below:\n\n![Image](https://github.com/user-attachments/assets/9212f9ff-a1a3-4c9b-8b2e-09296a1d1b0b)\n\n## Users\n\nOpenStudio-ERI is used by a number of software products or organizations, including:\n\n- [APEX](https://pivotalenergysolutions.com)\n- [Clarity Common Engine](https://psdconsulting.com/solutions/)\n-
