Dear All When i was trying to make a new wall type in the wall type manager; i couldnt explain how the Uvalue in the wall type manager is calculated, for istance:
if i make a wall with a single layer of 0.1 m of Concrete U-value = 4.595 and if i make a wall with a single layer of 0.2 m of Concrete (same layer type) U-value=3.770 but normaly the U-value will be devided by 2 if i double the thikness form 0.1 to 0.2!!! I tried to change the values of convective heat transfert coefficient but the Uvalue didnt change: So how we can explain theses values the U-value ?
