glass_area); At the end of the calculations, the window displays OutputJFrame: • a summary of the values of the selected items (type, size, frame profile, glass, climate zone) in the main GUI StartJFrame; • the value of the global transmittance for the selected geometric dimensions; • the value of the global transmittance for the standard geometric dimensions; • a message shows if you respect the limit of transmittance depending on the climatic zone selected;preview of 2D images of the sections of interest to the selected type of frame; • a button to show the heat flow in sections of interest; • a button that lets you adjust the zoom feature images; The controls in the window object OutputJFrame and layout of the output window are managed using the class ImageControls. Changing several times the combination of the selected items in the main GUI and starting the calculation again with the button JButton calcola_UwActionPerformed, you can simultaneously view OutputJFrame windows corresponding to different combinations in order to allow a comparison of the results of processing. Conclusion: future developments This tool has been currently developed for some types of door and window frames in combination with different types of glass. Furthermore, the tool is designed to provide to the manufacturers of window frames an useful tool for the choice of the most effective components. The research is still under development, to extend the processing of the heat flow to parts of shell containing also opaque elements. To better understand the energy performance of a building the first step consists in the assessment of the features of the building envelope, both transparent and opaque, in order to obtain the global energy needs, useful to the choice of the action to carry out on the construction. Another important result could be the development of a plugin that allows to evaluate the economic advantages associated to the better choice, through a cost-benefit analysis that takes into account both the initial costs and the obtainable energy savings.
