OpenStudio®-ERI (Energy Rating Index (ERI) Workflow) [SWR-18-72] 1.7.0 Released 12/14/2023

The OpenStudio®-ERI project allows calculating an Energy Rating Index (ERI) using the Department of Energy's open-source OpenStudio®/EnergyPlus® simulation platform. The building description is provided in an HPXML file format. 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 ZERH Certification Using an ERI Compliance Path For more information on running simulations, generating HPXML files, etc., please visit the documentation at https://openstudio-eri.readthedocs.io/en/latest/

EnergyPlus™ v.23.2.0 2023 [SWR-17-23]

EnergyPlus™ is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption and water use in buildings. This is the EnergyPlus Development Repository. The Department of Energy maintains a public website for EnergyPlus where you can find much more information about the program. https://energyplus.net/ For detailed developer information, consult the wiki. https://github.com/NREL/EnergyPlus/wiki Many users (and developers) of EnergyPlus are active on Unmet Hours, so that's a great place to start if you have a question about EnergyPlus or building simulation. https://unmethours.com/questions/ For more in-depth, developer-driven support, please utilize the EnergyPlus Helpdesk. https://energyplushelp.freshdesk.com/support/home

OpenStudio® Resources [SWR-07-40]

This repository includes a suite of simulation tests that can be used to validate new OpenStudio® model objects as well as ensure that objects continue to work after they are added. Each new OpenStudio Model object should ideally have two simulation tests associated with it: - a Ruby one which verifies the Ruby API and, - an OSM one that verifies the OSM file can be loaded with future versions of OpenStudio. Both tests should result in a simulation-ready OpenStudio Model that can be simulated using EnergyPlus®. Both of these tests are located in the /model/simulationtests directory, the easiest way to add a new test is to find a related existing test and modify it. When new tests are added they must be added to the model_tests.rb file.

OpenStudio® Standards [SWR-07-40]

OpenStudio® Standards is a Ruby Gem library that extends the OpenStudio SDK. It has four main use-cases: Provide higher level methods to help BEM users and developers to create OpenStudio models from existing geometry, or programmatically generated geometry Create typical building models in OpenStudio format Create a code baseline model from a proposed model Check a model against a code/standard openstudio-standards previously supported making the DOE/PNNL prototype buildings in OpenStudio format. This has since been deprecated, as the DOE/PNNL prototypes are intended for specific code comparisons under the Energy Policy Act and are not intended to accurately represent typical existing or new buildings. While openstudio-standards still creates typical buildings, these are not the same as the DOE/PNNL prototypes.
