DESCRIPTIONDOE2.1E-121 is a set of modules for energy analysis in buildings. Modules are included to calculate the heating and cooling loads for each space in a building for each hour of a year (LOADS), to simulate the operation and response of the equipment and systems that control temperature and humidity and distribute heating, cooling and ventilation to the building (SYSTEMS), to model energy conversion equipment that uses fuel or electricity to provide the required heating, cooling and electricity (PLANT), and to compute the cost of energy and building operation based on utility rate schedule and economic parameters (ECONOMICS). DOE2.1E-121 contains modifications to DOE2.1E which allows 1000 zones to be modeled. 
PACKAGE CONTENTSMedia Directory; Software Abstract; Note on DOE2.1E-121; Media Includes LA-7689-M(Ver.2.1)Pt.1 and Pt.2, LBL-11353, LBL-34946, LBL-34947, document updates 1, 2, 3, 4, Source Code, ReadMe, Executable, Auxiliary Material, Compilation Instructions, Linking Instructions, Sample Problem Input and Output;\1 CD ROM

MEDIA QUANTITY
METHOD OF SOLUTIONHeat conduction through walls is determined with response factors. Thermal mass effects are calculated with room weighing factors. Hourly simulation of heating and cooling equipment is quasi-steady state using performance curves. 
COMPUTERIBM PC 
OPERATING SYSTEMSMicrosoft Windows 95, 98, NT, or XP 
SOFTWARE LIMITATIONSDOE2.1E-121 supports modeling of up to 1000 zones. 
RELATED SOFTWAREWeather data processor program. UPDATE program for processing program modifications. 
UNIQUE FEATURESInput Functions allow users to enter FORTRAN-like routines in the input to modify the program calculations without recompilation. Macros allow input of parameters that are mathematical expressions instead of fixed values. Parametric run feature simplifies doing sensitivity analyses. LOADS and SYSTEMS output files can be saved for reuse to reduce calculation time. Building Description Language simplifies input of building data. Hourly reports allow detailed examination of building performance. 
OTHER PROG/OPER SYS INFOFile naming conventions: .SRC UPDATE source file, .UPL UPDATE program library, .MOD UPDATE modification file, .FOR FORTRAN source code, .OBJ object file, .EXE executable file, .TMP temporary file, .BIN binary file, .DAT ASCII data file,. INP input file, .INC include file for macro input, .OUT output file.
