[TRNSYS-users] windows in Trnsys

[Kersken, Matthias]

Dear Mr. Beuckelaer!
 
Type35a/b (Windows) could be used for a "manual" window; the ratio of energy
transmittance must be supplied as an input.
 
When You create a TRNSYS-glazing in window5 You HAVE TO CHOOSES A FIX frame
to avoid a TRNSYS-error. TRNSYS ignores this fixed frame.
Please refer to: http://www.trnsys.com/FreeDownloads/WindowTutorial.pdf
 
With best regards,

Betreff: [TRNSYS-users] windows in Trnsys



Dear Trnsys-users,

 

I’ve some question concerning windows in Trnsys. When you want to implement
a window (with a known U-value and g-value) but there is no corresponding
window in the library, can you somewhere adapt the U-value and g-value?

I know you can use window5 to make a new window in your library, but
sometimes I don’t know the layers of my window but just the U-value en
g-value. Can you adapt perhaps the values of the additional heat resistance
of an external shading device to achieve the wanted value? Or adapt the
U-value of the profile? 

 

When you do use window5: you have to introduce a profile too.  But in
trnsys, you select the created window under “Glazing”. Do you then still
have to introduce the U-value of the profile in Trnsys or 
 ?

 

Thanks in advance,

  Joke De Beuckelaer    
  project engineer
