v1.9.4

OpenStudio-ERI version 1.9.4 has been released. 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 v1.9.4 uses OpenStudio v3.9.0, EnergyPlus v24.2.0, and HPXML v4.1-rc1. Please visit the OpenStudio-ERI v1.9.4 documentation for instructions on how to get started, how to connect software tools to the workflow, etc. The full set of US TMY3 weather files can be obtained from here.

New Features

  • Adds ENERGY STAR ERI calculation for SFNH National v3.3 and MFNC National v1.3.
  • Updates to ENERGY STAR SFNH Rev 14 and MFNC Rev 05.
    • Breaking change: Building types "single-family detached" and "single-family attached" may only be used for SFNC versions and "apartment unit" may only be used for MFNC versions.
    • ENERGY STAR MFNC National 1.2 now uses 100% LED lighting.
  • WeatherStation/extension/EPWFilePath is now optional; if not provided, the closest TMY3 weather station will be automatically selected based on the zip code.
  • Improves eGrid/Cambium region lookup by zipcode when an exact match is not found.

Bugfixes

  • Fixes ZERH Target Home and ESRD so that operable window fraction (for natural ventilation) from the Rated Home is preserved.
  • Fixes possible error if there's a surface w/ interior unconditioned space and exterior "other housing unit".
