OpenStudio®-ERI
The OpenStudio-ERI project allows calculating an Energy Rating Index (ERI) using the Department of Energy's EnergyPlus™ simulation platform.
The building description is provided in an HPXML file format.
OpenStudio-ERI is intended to be used by user interfaces or other automated software workflows that automatically produce the HPXML file.
The project supports:
- ANSI/RESNET/ICC 301© Standard for the Calculation and Labeling of the Energy Performance of Dwelling and Sleeping Units using an Energy Rating Index
- ENERGY STAR Certification System for Homes and Apartments Using an ERI Compliance Path
- IECC ERI Compliance Alternative (Section R406)
- DOE Efficient New Homes (formerly Zero Energy Ready Homes) Certification Using an ERI Compliance Path
For more information on running simulations, generating HPXML files, etc., please visit the documentation.
OpenStudio-ERI uses OpenStudio-HPXML to run the individual EnergyPlus simulations.
