[TRNSYS-users] windows

Dear Douglas,
   I don't think that you made a mistake. The window property values that 
you see in the zone window description come from the brief window 
description that you put into prgwin in step 5. These values correspond to 
Window 5's "total window results" field. The properties that you see in the 
WinID Pool are "center of glass" values taken from data in the DOE2 report. 
Using the U-value as an example (in red), the data comes from:

Overall and Center of Glass Ig U-values (W/m2-C)
Outdoor Temperature                 -17.8 C      15.6 C      26.7 C      37.8 C
Solar      WdSpd  hcout hrout  hin
(W/m2)     (m/s)     (W/m2-C)
    0        0.00  12.25  3.23  7.54  1.29 1.29  0.86 0.86  0.80 0.80  1.12 
1.12
    0        6.71  25.47  3.21  7.55  1.35 1.35  0.89 0.89  0.81 0.81  1.15 
1.15
  783        0.00  12.25  3.37  8.14  1.43 1.43  1.20 1.20  1.06 1.06  0.89 
0.89
  783        6.71  25.47  3.29  8.03  1.52 1.52  1.27 1.27  1.14 1.14  0.89 
0.89

However, whatever you see displayed in TRNBuild (either in the Zone Window 
or in the WinID-Pool) is just for display purposes. Type56 performs its own 
calculation of window u-value and SHGC internally during each time step of 
the simulation. There are Type56 outputs (NTYPEs) that will allow you to 
see the values that Type56 is actually calculating for the window properties.

Kind regards,
  David
