DOE-2 Reference Manual Version 2.1 - DOE2.com

B. PROGRAM PACKAGEThe DOE-2 program package for CDC and IBM computers is available in twoparts: Magnetic tape FORTRAN source decks of the program and auxiliaryroutines, control and run information, sample problem decks, and weather filelibrary data; printed documentation, and a National Energy Software Centernote descri bi ng the transmi tt al tapes.Listings of DOE-2 are available from the National Energy SoftwareCenter. If any, problems ari se with the magnet i c tape copy, ass i st ance isavailable by telephoning the Center. Punched card copies of the program arenot available, because the program is too large.C. EXECUTIVE SUMMARYDOE-2 enables architects and engineers to compute energy consumption inbuildings. The program can simulate hour-by-hour performance of a buildingfor each of the 8760 hours in a year. A new computer language, the BuildingDescription Language, has been written. It is a computer language for analysisof building energy consumption that permits the user to instruct a computer infamiliar English terminology.Building Description Language has been developed primarily to aidengineers and architects in the difficult and time-consuming task of designingenergy-efficient buildings that have low life-cycle cost. The energy consumptionof a building is determined by its shape; the thermal properties ofmaterials; the size and position of walls, floors, roofs, windows, and doors;and the transient effects of shading, occupancy patterns, lighting schedules,equipment operation, ambient conditions, and temperature and humidity controls.Energy consumption is affected, also, by the operation of primary and secondaryHVAC systems and by the type and efficiency of the fuel conversion (plant)equipment. Furthermore, the life-cycle cost of operatingoa building underdifferent economic constraints can strongly influence basic design deciSions.DOE-2 also provides a means of performing the complicated analysis ofenergy consumption without the necess ity of instruct i ng the program correct lyin every minor detail. A set of default values (numbers used for the value ofa variable if the user does not assign one) is included, to reduce the amountof input that must be supplied in order to run the program.Figure 1.1 shows a brief organizational outline of the DOE-2 computerprogram.1. Program ControlDOE-2 consists of more than 30 files, not including the weather data.Hence, assuring that the subprograms are properly executed requires a substantialnumber of bookkeeping functions, which are performed by a sequence ofjob control instructions. The job control instructions are unique to eachsite, because they interact with the particular operating system in use atthat site. Local DOE-2 Site Manuals provide the site-specific instructionsand procedures that are required for DOE-2 program control.1.3 (Revi sed 5/81)
