OpenStudio-ERI version 1.1.1 has been released. Two packages are available, a minimal zip with a handful of weather files and full zip with all US TMY3 weather files.

The OpenStudio-ERI workflow calculates an Energy Rating Index (ERI) using the Department of Energy's OpenStudio/EnergyPlus building simulation platform. The open-source workflow is intended to be used by residential software tools that provide a HPXML building description file.

OpenStudio-ERI v1.1.1 uses OpenStudio v3.1.0, EnergyPlus v9.4.0, and a proposed HPXML v3.1.

Please visit the OpenStudio-ERI v1.1.1 documentation for instructions on how to get started, how to connect software tools to the workflow, etc.
