Is possible also allows a larger view of the profile and of the heat flow to provide better detail understanding of the temperature values obtainable. To make a new search, or if the transmittance values are unsatisfied, you can reselect the main window, leaving open the output window previously generated, and change the combination of one or more elements rerunning“ CALCULATE THE TRANSMISSION”. In this way, the tool will open a new output window and you can compare the results generated by combinations selected( Fig. 5).
System operation
The tool has been designed using the software LBNL WINDOW and LBNL THERM. It was acquired authorization for the use of such software by asking the acceptance of their license by the user. This option was included in the startup screen of the program. The tool can be downloaded to your computer from the www. padesignsrl. com website. The application was developed in Java and uses the Swing library to create graphical components( windows, panels, frames, buttons, labels, text boxes etc.) which are used in the GUIs. UpadMain is the class that contains the main method that starts the application and instantiates the class InfoLicenzaJFrame( which extends the superclass JFrame). This class creates a window that displays the text of the license terms and the buttons to accept(“ I Agree”) or refuse(“ I Disagree”) such conditions in order to be able to perform or not the application. If you accept the terms, it is instantiated class StartJFrame. This class has the task to display the main program window. The default constructor StartJFrame first initializes the GUI components. Later calls initDatiTabelle that takes care of instantiating the class DBManager. DBManager manages the database containing the data used by the software. A SQLite library is used to integrate a relational database within the application. A SQLite file contains the data of climatic zones, profiles of frames, glasses and the type of fixtures( Fig. 6).
