Hi Antoine,
as you mentioned, the U-Value is calculated based on the thermal properties of the glazing. The U-Value
displayed in TRNBuild is the U-value computed according to the reference conditions given in the standard EN410.
It is only used for user information and supports choosing the right glazing.
Best

Betreff: [TRNSYS-users] Effective use of overall glass transmission coefficient by Trnbuild
Hi
Looking at the documentation p. 5-111 (Window data used by the Type 56) and 5-167 (Heat Flux between Window Panes) I do not understand what is the exact use of the overall glass transmission coefficient in Trnbuild. Indeed it seems that the overall transmission is rather computed based on the physical properties of glass and gap layers. If the value from the Window file is indeed used could you please confirm me the actual ambient conditions: have they been changed to be closer to the standardized ones?
Thanks a lot for your help
