Overview
The Elite Software EZDOE program is an easy to use IBM PC version of the U.S. Department of Energy (DOE) program known as DOE-2.1. EZDOE calculates the hourly energy use of a building and its life cycle cost of operation given information on the building's location, construction, operation, and heating and air conditioning system. Using hourly weather data and algorithms developed by Lawrence Berkeley Laboratory, EZDOE is a dynamic program that takes into account complex thermal storage effects of various building materials. In addition, EZDOE can also accurately simulate the operation of all types of heating and cooling plants including ice water thermal storage and cogeneration systems. Up to 22 different air handling systems each with multiple control options are supported. The types of heating and cooling plants allowed is nearly infinite as thousands of combinations of chillers, boilers, furnaces, pumps, and cooling towers are allowed. There is even provision for user defined plants and performance curves. The economic analysis capabilities of EZDOE allow for complex utility rate structures, fuel costs, initial equipment costs, replacement costs, and annual costs for non-plant items and baseline data for comparative runs. A large library of over 230 hourly weather data files is available for EZDOE. One weather data file of your choice is supplied with EZDOE while others are available at additional cost. Although EZDOE provides all the advanced features of the full mainframe DOE-2.1d version, it is still very easy to use. Windows, menus, electronic mouse support, full screen editing, and dynamic error checking all combine to make EZDOE a state of the art user friendly program.
Calculation Method
The calculation procedures used in EZDOE were developed by the Lawrence Berkeley Laboratory (LBL) in Berkeley, California primarily for use by the U.S. Department of Energy (DOE). Elite Software continually updates EZDOE to stay abreast of the latest LBL calculation enhancements to the DOE program. The current version of EZDOE uses the calculation procedures of version 2.1d of the DOE program
Program Input
EZDOE uses full screen editing features that provide a simple "fill in the blank" data entry procedure. All input data is checked at the time of entry so that no improper data can be entered. If you have a question about what the program is requesting, you can press the "?" or F10 key to obtain additional help explanations. All data is saved to disk as it is entered. Four major types of data are requested: Loads, Systems, Plants, and Economics. Load data contains the building and space dimensions, wall and glass orientations, construction materials, people, lighting, equipment, and much more. The Systems data involves all information concerning air handling and heat delivery systems. VAV, constant volume, PTAC, dual duct, two/four pipe fan coils, and radiators are just a small sampling of the many system types supported by EZDOE. The Plant data concerns the cooling and heating equipment such as chillers, boilers, cooling towers and pumps. The Economic section considers initial, annual, cyclical, replacement, and operating costs.
Program Output
EZDOE offers all of the standard reports as does the mainframe computer version of DOE. These reports can be viewed on the screen, stored in a disk file, or printed. Shown below are just two of the scores of reports available.
System Requirements
This DOS software application must be run in a full MS-DOS environment to perform calculations. Please check to be sure that your computer has access to read/write in a full MS-DOS environment. An example of such an environment is to restart a computer in MS-DOS mode. Note that the newest operating systems such as Windows XP DO NOT support full MS-DOS mode! (There are advanced methods to emulate this environment, but are not easy for the average user and/or require the purchase of extra DOS utilities such as NTFSDOS Pro.)
If your computer supports full MS-DOS mode, basic hardware requirements include a PC with clock speed 75MHz or higher, 16MB of RAM, 20MB of available hard-disk space, floppy drive, CD-ROM drive, and monitor. Additionally, 25 MB of hard disk space is required to install and run EZDOE.
