DOE-2 Engineers Manual Version 2.1A - DOE-2.com

1.4 Volume IV - Engineers Manual
This manual, as stated earlier, provides the information needed for understanding
"what happens to the input data" to the DOE-2 computer program.
It contains a summary of the equatlons and algorithms used to perform the calculations.
The relationship of the DOE-2 algorithms to ASHRAE algorithms is
also given and is traced to the ASHRAE documentation.
1.5. Site Manuals
In addition, further user guidance is available in Site Manuals, which
provide the necessary information for the use of DOE-2 at specific computing
installations. These manuals are not provided by the National Technical Information
Service, but rather are available from the computing installations.
2. PROGRAM PACKAGE
The DOE-2 program package for CDC and IBM computers is available in two
parts:
(a) Magnetic tape (FORTRAN source) of the program and auxiliary routines
with control/run information, sample problem decks, and weather file
library data plus
(b) Printed documentation.
Listings of DOE-2 are available from the National Energy Software
Center. If any problems arise with the magnetic tape copy, assistance is
available by telephoning the Center. Punched card copies of the program are
not available, because the program is too large.
3. SUMMARY OF PROGRAM
DOE-2 enables architects and engineers to compute energy consumption in
buildings. The program can simulate hour-by-hour performance of a building
for each of the 8760 hours in a year. A new computer language, the Building
Description Language, has been written. It is a computer language for
analysis of building energy consumption that permits the user to instruct a
computer in familiar English terminology.
Building Description Language has been developed primarily to aid engineers
and architects in the difficult and time-consuming task of designing
energy-efficient buildings that have low life-cycle cost. The energy consumption
of a building is determined by its shape; the thermal properties of materials;
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
secondary HVAC systems and by the type and efficiency of the fuel conversion
(plant) equipment. Furthermore, the life-cycle cost of operating a building
under different economic constraints can strongly influence basic design decis
ions.
