|A geometric thermal bridge|
The first image of this article shows an Energy2D simulation of the material thermal bridge (discontinuities in thermal conductivity of materials such as steel studs in walls). The second image shows an Energy2D simulation of the geometric thermal bridge (discontinuities in cross section of heat flow such as junctions of two planes).
The following is an excerpt from Dr. Khemlani's article:
"Another ArchiCAD feature that OWP uses extensively is its Thermal Bridging analysis tool, which allows a 2D heat-flow simulation to be run on any element to identify those parts of the building that are responsible for heat loss and might cause vapor condensation as well as other unwanted effects. Again, OWP uses this in conjunction with Energy2D, another tool that provides not only thermal bridging analysis but can also run sophisticated CFD (computation fluid dynamics) simulations, allowing OWP to test out different materials and composites for building components."
