Re: [EnergyPlus_Support] Intermediate Building Layer Temperatures





Hi Mrs. Lawrie,

I've just received your reply from the Helpdesk system. I solved crash problem when I removed the material defined as Material:InfraredTransparent.
Now I can run simulations and get CondFD Nodal Temperature values for every building surface (including glazing materials). The thing is EnergyPlus generated results for a number of nodes (which is different for each surface). For example I have a partition wall with  3 nodes reported, or a floor slab with 11 nodes reported.
I'd like to learn how E+ defines the number of nodes to be reported? Are the nodes representing mid-layer or layer-surface temperatures?
Thanks so much.
Regards.

Omer T. Karaguzel

Your file did not crash due to that.  I have already replied from the helpdesk.

Hi All,

My question is about EnergyPlus  output variables:
Is there are method to get surface temperature values of intermediate building layers that make up the whole envelope construction assembly ?
Normally, inside and outside temperature of building surfaces are reported. I tried to use Conduction Finite Difference (CondFD) as a surface heat balance algorithm instead of the usual CTF (Conduction Transfer Function).
According to E+ input/output reference, one of the CondFD outputs is "CondFD Nodal Temperature [C]" for each node in the surface simulated. However, E+ crashes with such input. I already send a ticket to E+ support system.
However, there may be another way of getting such a variable from E+ which I may be ignoring now.
Thanks for the replies.
Best.
