N1 - Funding Information:
For the past 20 years, the U.S. government has maintained and supported two building energy simulation programs, DOE-2 and BLAST. DOE-2, supported by DOE, has its origins in the Post Office program written in the late 1960s for the U.S. Post Office. BLAST, supported by the U.S. Department of Defense (DOD), has its origins in the NBSLD program developed at the U.S. National Bureau of Standards (now the National Institute of Standards and Technology) in the early 1970s. The primary difference between the programs is the underlying method for calculating zone loads—DOE-2 uses a room weighting factor approach, while BLAST uses a heat balance approach.

N2 - In 1995, the U.S. Department of Energy (DOE) began planning for a new generation of building simulation tools. As p art of this planning activity, DOE created an inventory of DOE-sp onsored tools in early 1996. By mid-1996, this work had evolved into a web-based directory with information on 50 software tools. Today, the directory contains information on more than 125 tools from around the world. To inform the simulation tool planning efforts, DOE sponsored workshops in August 1995 and June 1996, inviting energy simulation developers and users. Af ter the two workshops, DOE began defining the structure and capabilitiesof a new building energy simulation tool by building on experience with two well-known p rograms: DOE-2 and BLAST. Development of the new p rogram, EnergyPlus, started in early 1996 and release is plannedfor 2000. EnergyPlus is intended to replace both DOE-2 and BLAS T. EnergyPlus will include innovative simulation features including variable time steps, built-in and external modular systems integratedwith a heat and mass balance-based zone simulation, interzone airflow, and new ground heat transfer modules. This paper describes the structure of the web-based tools directory, the results of the two workshops, the capabilities and structure of Ene rgyPlus, and DOE’ s fu ture plans for building simulation tools development.
