       The u-value (and g-value) shown in the upper right corner of the
    TRNBuild window type manager are for display only; these values are
    simply read out of the w-4 library. At the end of the file, you will
    find some lines that look like the following:<br>
    <br>
     11015 OPTWHITE15                                   15           <font
      color="#ff0000">5.5</font>    <font color="#0000ff">0.87</font>    
    0.852    0.075   0.90    1   15.00<br>
     12001 Pilkington,OPTITHERM,Coating#3               4/16/4       <font
      color="#ff0000">1.3</font>    <font color="#0000ff">0.64</font>    
    0.516    0.213   0.76    2   24.00<br>
       <br>
    The u-value fields are shown in red, the g-value (SHGC) values are
    shown in blue. You can write whatever numbers you want in those
    fields; TRNBuild picks them up and displays them.<br>
    Kind regards,<br>

            a windows with desired properties. I manipulated the
            configuration so that the outcome u value is 1.88 which I
            wanted it to be. Following the window-defining tutorial, I
            was able to transport the information into TRNSYS
            by modifying the W4-lib file and Prgwin.lib file. However,
            when I selected it from the windows library, the shown value
            was 1.63. Can anyone provide some possible explanations?
