Diagram of PartialOpaqueSurfaceOpen the diagram

Extends from IDEAS.Buildings.Components.Interfaces.PartialSurface (Partial model for building envelope component).

Information

This model extends IDEAS.Buildings.Components.Interfaces.PartialSurface with parameters that are typical for opaque surfaces, i.e. all surfaces except windows.
