Re: [EnergyPlus_Support] Node Numbers in wall construction

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

Here's how Mike answers the question:

Node 1 is the inside face of the
surface, and node N is the outside face of the surface. The placement of
the other nodes is documented in the Construction CondFD report in the
eio output file. It lists the distance for each node and what materials
are on either side of the node. To get this report, use
Output:Constructions,Constructions;


The output works for all nodes that are present, see example file
CondFD1ZonePurchAirAutoSizeWithPCM.idf. It outputs
ZN001:WALL001 Node #1:CondFD Nodal Temperature[C](Hourly)
ZN001:WALL001 Node #2:CondFD Nodal Temperature[C](Hourly)
