# .AixLib.ThermalZones.HighOrder.Components.Shadow.ShadowEffect

Shadow effect of horizotal shield, reducing the solar radiation through the window

## Information

Overview

This model represents the reducing effect of solar radiation caused by the shadow on the window surface.

Concept

The model calculates the ratio of the shadow on the window glazing area to determine the radiation reduction.

- For the area without shadow, the solar radiation remains unchanged.
- For the area with shadow, the direct radiation is reduced to zero, the diffuse radiation is reduced according to the defined type.

Assumptions

- The diffuse radiation has a vertical incident angle between 0° (horizontal to the ground) and 90° (vertical to the ground, upward).
- The reduction of reflected radiation is not considered.
