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 and PowerDOE. This site is maintained by and for EnerLogic and 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. |

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 3.6 and 3.61b are the current releases. 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, or directly download the eQUEST Tutorial. You can also view the eQUEST download area to see recent versions of the program, documentation and updates. New Note: eQUEST 3.6 and D2comply 3.6 were approved by the California Energy Commission as 2005 Title 24 non-residential ACMs by the CEC at their 11 April 2007 business meeting. eQUEST 3.6 and 3.61b are approved for use with Savings By Design. eQUEST is supported as a part of the Energy Design Resources
program which is funded by |

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 “DOS
box” or “batch” 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 and PowerDOE; we
strongly recommend you consider eQUEST before trying to use
“plain” DOE-2. D2comply
is a DOE-2.2 based California Title 24 compliance engine; D2comply 3.55
was approved by the California Energy Commission as a 2001 Title 24 non-Residential
ACM on 4/27/2005; the D2comply 3.6 2005 Title 24 non-Residential ACM is not yet certified by the CEC but
will be submitted for certification during August 2006. 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 DOEWth
which can process NOAA/NCDC (TRY, TMY, etc.) files into
eQUEST/DOE-2/PowerDOE (bin) files.
Utilities are also available to process eQUEST/DOE-2/PowerDOE (bin)
files, including the capability to list, convert to/from text format, create
statistical summaries, and other functions. |

PowerDOE is our previous generation (“legacy”) application; use eQUEST for the most up-to-date user interface and DOE-2 simulation capabilities. It is a powerful and flexible building energy use and cost estimation tool which includes a graphical user interface that provides 2-D and 3-D displays of your building layout including architectural and HVAC features as well as graphical modeling results. PowerDOE includes an earlier version DOE-2.2 as its simulation "engine" for all energy and cost calculations. PowerDOE is a complete implementation of the original version of DOE-2.2 features including interactive dynamic recalculation of input defaults. A full-featured PowerDOE,
including its "Quick Start Guide" and "Tutorial" is
available free under 90 day
evaluation licensing. Licensed users can download the current
version (v1.18g dated |

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 (see here)
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 2006 USDOE energy price escalation rates and is
available FREE in Excel OfficeXP format (4/19/06.) View a
detailed description of this spreadsheet tool (sample screens,
advantages, limitations) or a summary
of recent enhancements. |
