Perimeter Zones Are Missing Interior Surfaces

When the energy model contains automatic perimeter/core thermal zoning, some analytical surfaces do not display.

To use perimeter zones for the energy model, in the Energy Settings dialog, define Perimeter Zone Depth, and select Perimeter Zone Division.

When you use perimeter zones, some interior surfaces and division surfaces (theoretical surfaces that divide the space into thermal zones) are not visible.

This behavior is expected. It has little to no impact on the energy simulation. Most spaces in these configurations are maintained at the same temperature. Therefore, no heat exchange occurs between the spaces.
