The weather converter program can ignore these (and just report them) or it can try to fix them with appropriate values. As shown in the IDD type description of the Weather Data, there are minimum and maximum values for several of the fields. This is a toggle option that once selected is saved in the registry with other options (for example, screen size) for the program.

The file menu has four options: Fix Out of Range Data

Main menu screen of the Weather Converter Utility File Menu See the section on EP-Launch in this document for more information on how to use EP-Launch with the weather utility program. Weather is one of the options on the Utilities tab in EP-Launch. For convenience, it automatically opens with the “convert” option.ĮP-Launch can also be used to run the weather utility program. (e.g., Start Menu EnergyPlus WeatherConverter). It is executed from the Start Menu programs using the specific folder where the EnergyPlus program was installed. The user front end is a simple to use program with standard graphical user interface menus. The DLL interface is described in a later section for those developers who might wish to access it directly. The utility consists of two parts: a user interface that executes on standard Wintel systems and a DLL that does the work of the processing. An additional “output format” from the utility is a comma-delimited file that can easily be imported into a spreadsheet program such as Excel™ for further user perusal, charting and/or editing. The utility also prepares an statistical summary of the weather data set as part of the processing. The processor makes the calculations necessary for supplying data (when data is missing) and calculates the Horizontal Infrared Radiation Intensity values – not typically currently an observed value reported by the meteorological offices through the world. The utility translates and extends typical weather data into the E/E format.

The utility also reads ESP-r (CLM format), DOE-2 (fmt format), BLAST (Ascii format) files and other files. We developed a utility for the E/E format to read standard weather service file types such as SAMSON and newer ‘typical year’ weather files such as TMY2, WYEC2, and IWEC.
