.IDEAS.Buildings.Components.OuterWall

Information

This is the main wall model that should be used to simulate a wall or roof between a zone and the outside environment.

Typical use and important parameters

See IDEAS.Buildings.Components.Interfaces.PartialOpaqueSurface for equations, options, parameters, validation and dynamics that are common for all surfaces.

In addition to these parameters, this model computes the shade cast by an outside object such as a building using IDEAS.Buildings.Components.Shading.BuildingShade if parameter hasBuildingShade=true. Values for parameters L, dh and hWal then have to be specified.

Options

The model IDEAS.Buildings.Components.Shading.BuildingShade is implemented by default but it can be redeclared in the advanced tab. In this case the user still has to provide values for L, dh and hWal to avoid failing an assert that verifies the parameter consistency. The values are however not used in this case. The correct shading parameter values should then be passed through the redeclaration.
