Thermal bridges - well you could do a kludge or you could use a tool such
as ESP-r which includes descriptive terms for linear thermal bridges for
each surface-edge junction and which includes their impact in the energy
balance. Ok it is a static representation rather than fully dynamic one
but folk in Europe tend to be paranoid about thermal bridges ;-)

Asunto: [EnergyPlus_Support] Modeling of Thermal Bridges ?
Hi all,
when entering the construction of the external walls the thermal bridges are neglected.
However for some buildings this can be a significant error. Therefore I am looking for the best way to include the psi-value (calculated with external program like THERM or HEAT) into the construction.
A quick and dirty solution would be to change the thermal insulation of the wall accordingly (i.e. change the thermal conductivity of one or some materials). However this could be tedious because it might be different for each room, so I get a lot of new pseudo-constructions in to my idf file.
Does anyone have a good solution for this?
Thanks,
Andres
