We are using TRNsys to simulate the effect of several measures on the heat consumption of a residential building. One of those measures is the use of low emissivity painting on the inner side of external walls.
Wanting to adjust the longwave emission coefficient, it is noted that the inside userdefined emissivities of surfaces can only be handled by the detailed model. In the menu of the radiation modes of the thermal zones however, this detailed model cannot be checked.
Any ideas on how to overcome this obstacle?
Kind regards,
