Through the next screen (Fig.4), you can check your input and start the calculation of transmittance, withdrawing from the database the information necessary to display the heat flow developed through the program THERM.

Figure 4: The screen c) shows a summary of the input. The screen d) shows the heat flow and the
thermal transmittance value
Subsequently appears the image of the heat flow with the relative temperature data. It also appears a red or green field depending on the compatibility of transmittance value achievable with
the requirements of European legislation for the limit values of the transparent elements.

than the other one
