DOE-2

Building Energy Use and Cost Analysis Tool




The Industry Standard...
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, usage, 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.

Proven Through Thirty Years of Development and Support…

For over two decades we have been developing and supporting DOE-2; this has lead to a very capable and feature rich product.  Over its lifetime several versions of DOE-2 have been developed and released to the public; we currently offer you our “latest and greatest” version, DOE-2.2, as well as continue to make available a “legacy” version, DOE-2.1E.  We suggest you use either DOE-2.2, DOE-2.3 or, even better, eQUEST which is our flagship DOE-2.2 and DOE-2.3 based interactive building energy use analysis product.

 

DOE-2.3 - The latest DOE-2 building energy simulation and cost calculation engine is DOE-2.3.  You can download a "release candidate" version of DOE-2.3 and its complete documentation from the DOE-2.3 download area, but you must complete a DOE-2.3 license agreement and scan/email, mail or fax it to us and we will then send you a password for the program zip archive; email and US mail address and fax number are on license.

 

DOE-2.2 - The current primary DOE-2 building energy simulation and cost calculation engine is DOE-2.2.  You can review an Overview of DOE-2.2 and learn about Converting DOE-2.1E input files to DOE-2.2.  You can download DOE-2.2 and its complete documentation from the DOE-2.2 download area, but you must complete a DOE-2.2 license agreement and scan/email, mail or fax it to us and we will then send you a password for the program zip archive; email and US mail address and fax number are on license.

D2comply - The new DOE-2.2 based California Title 24 compliance engine. D2comply 3.6 was approved by the California Energy Commission as a 2005 Title 24 non-Residential ACM in April 2007.  This is the component used by eQUEST version 3.6 to perform Title 24 compliance analysis; third party developers can use this package to build additional certified tools.  For full standard DOE-2.2 use you should obtain a standard release version of DOE-2.2 as mentioned above.

DOE-2.1E - Versions of the older DOE-2.1E and its complete documentation set can be downloaded from the DOE-2.1E download area, but you must complete a DOE-2.1E license agreement and scan/email, mail or fax it to us, and we will then send you a password for the program zip archive; email and US mail address and fax number are on license.

DOE-2 on CD - To obtain a DOE-2 CD, with program versions, documentation and weather data, mail the appropriate license(s) to us with a payment of $55US (add $5US for Canada, $10US outside North America.) US mail address to send your license(s) and payment is found on the DOE-2 license agreement.

The latest Breakthrough in DOE-2 Building Energy Use Modeling is here…

eQUEST = enhanced DOE-2.2 + Wizards + Graphics
eQUEST is a sophisticated, yet easy to use, freeware building energy use analysis tool which 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 model creation wizards, an energy efficiency measure (EEM) wizard and a graphical results display module with an enhanced DOE-2-derived building energy use simulation program.  You can review the eQUEST Overview to get a more complete summary of the features and capabilities of this excellent program.

You can review more information about eQUEST including download of program and documentation, or directly download the eQUEST Tutorial. You can also view the eQUEST download area to see recent versions of the program, documentation and updates. 
 

DOE-2 Version Downloads:

NEW DOE-2.3  (release candidate of latest technology simulation engine)

Release Candidate (Version 49) of DOE-2.3

Download a DOE-2.3 version 49m (new 3/14/2016) for Microsoft Windows (best with Windows 10/8/1/8/7/XP.(size: ~43.1 MB)

This archive contains the current release candidate of DOE-2.3.  DOE-2.3 is termed a release candidate as we do not yet consider DOE-2.3 a full replacement for DOE-2.2 but expect that will happen eventually. Some DOE-2.2 features are not yet available in DOE-2.3, however DOE-2.3 has a more robust HVAC equipment modeling and simulation alogorithm and solution approach.

DOE-2.3 is one of the simulation "engines" used in eQUEST.

NEW: Effective 30 September 2009, DOE-2.2 is Qualified Software (DOE-2.2-047dfor Calculating Commercial Building Tax Deductions first enacted under the Energy Policy Act of 2005 (EPACT) and later extended by the Emergency Economic Stabilization Act of 2008. 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 with further guidelines provided by DOE.  The submission packages, including ASHRAE Standard 140 testing, can be found here.

Download the DOE-2.2 refrigeration only version 50a for Window (best with XP but works for 95/98/ME/NT/2000.) This archive contains only the refrigeration DOE-2.2 release; this version is designed to model buildings using engineered refrigeration systems not conventional commercial building HVAC systems. This version is used to model Supermarkets, “big box” grocery stores, refrigerated warehouses, and industrial facilities with processing cooling equipment; most of the conventional HVAC systems found in the standard version of DOE-2.2 are not included in this version.  This archive includes a simple Windows executable, winDOE2, to run DOE-2 in its DLL format (same DLL’s used by the eQUEST refrigeration version) as well as the “DOS box” (.exe) batch version. The archive also contains readable program source (for BDL, simulation components, as well as support programs and data bases) and developer’s libraries (allowing third party developers to incorporate DOE-2.2 into their applications.) You will also need the DOE-2.2 Manuals and especially the refrigeration addendum to Volume 2, to use this program effectively. (posting date: 7/22/2008, ~7.9 MB)

Download D2comply for compliance only analysis; for full standard DOE-2.2 use you should obtain a standard release version of DOE-2.2 above NOT this version. D2comply accepts any valid DOE-2.2 BDL file that includes all required compliance information (see Volume 5: Compliance Analysis) and performs Title 24 compliance analysis. If you have eQUEST 3.6 you do not need D2comply. Check the CEC approved program list to see all approved software. (posting date: 3/9/2007, ~11 MB) 

NEW: On 23 December 2009 eQUEST 3.64 and D2comply 3.64 were submitted to the California Energy Commission for approval as 2008 Title 24 non-residential ACMs. These versions will be released once the CEC has reviewed the application and determined if modifications are required for approval.

Note:  The DOE-2.2 Manuals are in Adobe's Portable Document Format (PDF.) These documents (as with other documentation files for DOE-2 and eQUEST) use PDF version 1.5 (Acrobat or Acrobat Reader version 6) and may not be opened with versions earlier than Acrobat 5; to update your Acrobat Reader go to the adobe site for the free download .  These manuals contain details of the DOE-2.2 Building Description Language (BDL) created and displayed by the eQUEST user interface as well as the descriptions of all DOE-2.2 output reporting capabilities. These documents are the basis of the eQUEST on-line help system but contain a more complete and up-to-date description of the details of the DOE-2.2 version within the current release of eQUEST.
