Re: [EnergyPlus_Support] External wall U value setting

["Jean Marais jeannieboef@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Exactly, that is why it is important when changing U-value by changing layers that the layer with the least specific mass (insulation layer) is the only one to adjust (as DesignBuilder does). Good point, Linda.

Note that if you use just U/R values for walls in the definitions for EnergyPlus, you lose the thermal mass effects that the specific thermal properties give.

Hi,

Is it possible to set U values of external walls in Energy Plus? I would like to give specific value instead of changing thermal properties (specific heat, conductivity etc) of each layer one by one.


Sincerely
