ResStock™, built on the OpenStudio platform, is a project geared at modeling existing residential building stocks at national, regional, or local scales with a high-degree of granularity (e.g., one physics-based simulation model for every 200 dwelling units), using the EnergyPlus simulation engine. Information about ComStock™, a sister tool for modeling the commercial building stock, can be found here.

This repository contains:

• Housing characteristics of the U.S. residential building stock, in the form of conditional probability distributions stored as tab-separated value (.tsv) files. Comments at the bottom of each file document data sources and assumptions for each.
• A library of housing characteristic "options" that translate high-level characteristic parameters into arguments for OpenStudio measures, and which are referenced by the housing characteristic .tsv files and building energy upgrades defined in project definition files
• Project definition files:
  • v2.3.0 and later: buildstockbatch YML files openable in any text editor
  • v2.2.5 and prior: Project folder openable in PAT
• Unit-level OpenStudio Measures for automatically constructing OpenStudio Models of each representative dwelling unit model:
  • v3.0.0 and later: OpenStudio-HPXML Measures
  • v2.5.0 and prior: OpenStudio Measures
• Higher-level OpenStudio Measures for controlling simulation inputs and outputs

This repository does not contain software for running ResStock simulations, which can be found as follows:

• Versions 2.3.0 and later only support the use of buildstockbatch for deploying simulations on high-performance or cloud computing. Version 2.3.0 also removed separate projects for single-family detached and multifamily buildings, in lieu of a combined project_national representing the U.S. residential building stock. See the changelog for more details.
• Versions 2.2.5 and prior support the use of the publicly available OpenStudio-PAT software as an interface for deploying simulations on cloud computing. Read the documentation for v2.2.5.
