Thank you for visiting DOE2.com. This site is the place where you can obtain information and products from the developers of DOE-2 and DOE-2 based products including eQUEST. This site is maintained by James J. Hirsch & Associates.
The DOE-2 software was developed by James J. Hirsch & Associates (JJH) in collaboration with Lawrence Berkeley National Laboratory (LBNL), with LBNL DOE-2 work performed mostly under funding from the United States Department of Energy (USDOE) and other work performed mostly under funding from a wide range of industry organizations and ourselves. This site, however, is not sponsored or endorsed by either USDOE or LBNL, and use of “DOE” in names in this site does not imply any endorsement or recommendation of any listed products or services by the United States Government, LBNL, or anyone else.
Follow this links to review a brief comparison of DOE-2.1E, DOE-2.2, eQUEST and PowerDOE. eQUEST is our most up-to-date complete building energy use simulation tool; it is free and contains a complete version DOE-2.2 and its documentation.
Note: Most documents posted on this website are published using Adobe's Portable Document Format (PDF) with most using PDF version 1.5 (created using Acrobat version 9) and may not be readable with versions prior to 6; to update your Acrobat Reader go to the Adobe site for a free download.
eQUEST® is a sophisticated, yet easy to use, freeware building energy use analysis tool that provides professional-level results with an affordable level of effort. eQUEST was designed to allow you to perform detailed comparative analysis of building designs and technologies by applying sophisticated building energy use simulation techniques but without requiring extensive experience in the 'art' of building performance modeling. This is accomplished by combining schematic and design development building creation wizards, an energy efficiency measure (EEM) wizard and a graphical results display module with a complete up-to-date DOE-2 (version 2.2) building energy use simulation program.You can read the eQUEST Overview to get a more complete summary of the features and capabilities of this excellent program.
eQUEST 3.65 is the most recent release.For descriptions of the new features read this document.eQ_WthProc can convert EnergyPlus (epw) files into eQUEST/DOE-2 (bin) files, see weather data area below.
You can see more information about eQUEST including download of program and documentation. You can also view the eQUEST download area to see recent versions of the program, documentation and updates.
Note:eQUEST is Qualified Software for Calculating Commercial Building Tax Deductions first enacted under the Energy Policy Act of 2005 (EPACT), later extended by the Emergency Economic Stabilization Act of 2008 and most recently extended and modified by the PATH Act of 2015. eQUEST 3.65 is qualified, effective 19 October 2016, for buildings placed into service on or after to January 1, 2016; eQUEST 3.63b is qualified, effective 9 September 2009, for buildings placed into service prior to January 1, 2016. The requirements for software to be qualified for use in these deductions were first covered by IRS Notice 2006-52 and then amplified by IRS IRB 2008-14 and again clarified by IRS IRB 2012-17 with further guidelines provided by DOE and added DOE guidelines for buildings placed in service in 2016 and later.The submission packages, including ASHRAE Standard 140 testing, can be found here.
DOE-2 is a widely used and accepted freeware building energy analysis program that can predict the energy use and cost for all types of buildings. DOE-2 uses a description of the building layout, constructions, operating schedules, conditioning systems (lighting, HVAC, etc.) and utility rates provided by the user, along with weather data, to perform an hourly simulation of the building and to estimate utility bills. The “plain” DOE-2 program is a “Command Prompt” program which requires substantial experience to learn to use effectively while offering researchers and experts significant flexibility; eQUEST is a complete interactive Windows implementation of the DOE-2 program with added wizards and graphic displays to aid in the use of DOE-2.
You can review more information about DOE-2 including download of program and documentation. We currently offer you our “latest and greatest” version as well as “legacy” version. DOE-2.2 is the newest DOE-2 building energy simulation and cost calculation engine. DOE-2.2 is the “simulation engine” contained within eQUEST; we strongly recommend you consider eQUEST before trying to use “plain” DOE-2. DOE-2.2 can run in windows versions from XP to 10. DOE-2.1E is the “legacy” version of DOE-2.

The Weather Data & Utilities page provides a description of and access to weather data processing utilities which provide a variety of pre-processed weather data compatible with eQUEST, DOE-2.x and PowerDOE. The available utilities include eQ_WthProc which can process EnergyPlus (epw) and DOEWthwhich can process NOAA/NCDC (TRY, TMY, etc.) files into eQUEST/DOE-2 (bin) files.Utilities are also available to process eQUEST/DOE-2 (bin) files, including the capability to list, convert to/from text format, create statistical summaries, and other functions.
PowerDOE is not available as it has been discontinued in favor of eQUEST. PowerDOE is our previous generation (1990's “legacy”) application; use eQUEST for the most up-to-date user interface and DOE-2 simulation capabilities. PowerDOE included an earlier version DOE-2.2 as its simulation 'engine' for all energy and cost calculations. Note that PowerDOE was designed for previous generations of Windows and will not operate properly when installed in more recent versions such as Windows 7. For this reason PowerDOE has been discontinued.
The Life-Cycle Costing (LCC) analysis method is recognized to reliably identify cost optimal building design solutions yet it is not widely used with confidence. The National Institute of Standards and Technology (NIST) and ANSI have suggested standardized LCC nomenclature and conventions so that the entire buildings industry can speak one 'language' when performing LCC analysis. NIST's LCC procedures are embodied in the Building Life-Cycle Cost (BLCC) Program; the NIST BLCC program and related utilities can be downloaded here. Although the LCC procedures used in BLCC have long been published (NIST Handbook 135 1995 Edition) some users express concern that BLCC does not display the intermediate details of its calculations. For this reason we have developed a spreadsheet version of BLCC procedures. Users of our spreadsheet version report greater confidence with its user-friendly 'glass box' implementation of BLCC. Our BLCC spreadsheet includes year 2015 USDOE energy price escalation rates and is available FREE in Excel OfficeXP format (April 2016 version posted 4/22/2016.) View a detailed description of this spreadsheet tool (sample screens, advantages, limitations) or a summary of recent (2015 version) enhancements.

SolTrace is a software tool developed at the National Renewable Energy Laboratory (NREL) to model concentrating solar power (CSP) systems and analyze their optical performance. Although ideally suited for solar applications, the code can also be used to model and characterize many general optical systems. The creation of the code evolved out of a need to model more complex solar optical systems than could be modeled with existing tools. SolTrace can be installed either using the official NREL packaged distribution or from source code at the SolTrace open source project website. NREL welcomes contributions from programmers to the simulation engine or to the interface and encourages interested persons to get involved. More information on contributing, compiling the source code, and license requirements is available on the project website.
More information is available.
The code uses Monte-Carlo ray-tracing methodology. The user selects a given number of rays to be traced. Each ray is traced through the system while encountering various optical interactions. Some of these interactions are probabilistic in nature (e.g., selection of sun angle from sun angular intensity distribution) while others are deterministic (e.g., calculation of ray intersection with an analytically described surface and resultant redirection). Because it replicates real photon interactions, the code can provide accurate results for complex systems that cannot be modeled otherwise. Accuracy increases with the number of rays traced, but larger ray numbers means more processing time. Complex geometries also translate into longer run times. The code (written in C++) is extremely fast and automatically takes advantage of every processor present in a particular Windows- or Mac-based operating system. Although the input is text (or spreadsheet), a plug-in is provided for the free solid modeling tool Trimble SketchUp that will allow users to graphically design and save optical geometries for SolTrace analysis.
SolTrace can be used to model parabolic trough collectors, linear Fresnel lens systems, power tower geometries, and point-focus optical systems (dishes and solar furnaces). It displays data as scatter plots and flux maps, and can save data for processing with other software. It also can model optical geometries as a series of stages composed of any number of optical elements that possess attributes including shape, contour, and optical quality. Stages can be either physical or virtual to allow for easier accounting of power and flux throughout the system. A scripting language is provided to allow the user to create parametric runs and additional functionality beyond the core ray-tracing capabilities.
With the release of the SolTrace open source project, the software has adopted semantic versioning in which the version number consists of three parts — the major, minor, and patch counters. The current version number represents the first release under the open source project and the third major version, and consequently, it is assigned the major index '3'. The current version can read SolTrace files from version 2016.12.22 and prior, although compatibility has not been extensively tested.
