Commercial Prototype Building Models

The U.S. Department of Energy (DOE) supports the development of commercial building energy codes and standards by participating in industry review and update processes, and providing technical analyses to support both published model codes and potential changes. DOE publishes its findings in an effort to ensure transparency in its support, and to make its analysis available for public review and use.

As part of DOE's support of ANSI/ASHRAE/IES Standard 90.1, researchers at Pacific Northwest National Laboratory (PNNL) apply a suite of prototype buildings covering 80% of the commercial building floor area in the United States for new construction, including both commercial buildings and mid- to high-rise residential buildings, and across all U.S. climate zones. These prototype buildings–derived from DOE's Commercial Reference Building Models–cover all Reference Building types (with the exception of supermarkets), and also an additional prototype representing high-rise apartment buildings. As Standard 90.1 evolves, PNNL makes modifications to the commercial prototype building models, with extensive input from ASHRAE 90.1 Standing Standards Project Committee members and other building industry experts.

The prototype models include 16 commercial building types in 17 climate locations (across all 8 U.S. climate zones) for recent editions of Standard 90.1. The current combination results in an overall set of 1,088 total building models (in EnergyPlus™ Version 8.0).

Table 1 contains a scorecard for each prototype building. The scorecard is a spreadsheet (Microsoft® Excel®, .xls, format) that summarizes the building descriptions, thermal zone internal loads, schedules, and other key modeling input information. The suite of prototype models is available for download (compressed, .zip, format) for the respective edition of Standard 90.1. Each file includes EnergyPlus model input files (.idf) and corresponding output files (.html) across all climate locations.

Downloads

Files can be downloaded either as a complete package, containing all building types, or by individual building type (see Table 1), either by specific Standard 90.1 edition or as a complete set.

PNNL has documented recent prototype model enhancements made through ongoing support for ANSI/ASHRAE/IES Standard 90.1. More detailed descriptions and applications of the prototype models are presented in the PNNL reports included on the Energy & Economic Analysis page. These reports further document the approach, methodology, and modeling strategy used to develop the prototype models and the resulting energy and cost savings.
