This document discusses shading devices, their purposes, types, and design considerations. Shading devices are used externally or internally in buildings to protect from direct sunlight and create a comfortable interior environment. They can reduce cooling loads and costs by decreasing heat gain, while also improving comfort and aesthetics. Common types include internal devices like curtains, blinds, and louvers, and external horizontal, vertical, and egg-crate shading. Effective shading design considers the sun path and dimensions to block sunlight at different angles. Examples of shading designs in buildings are provided.

3.  Shading devices are
equipments that are used
externally or internally or
in between the building
spaces to protect from
direct sunlight.
 Objective is to create
comfortable internal
environment

4. WHY SHADING DEVICES ?
• To reduce heat gain during summer, reduce the cooling loads and
therefore minimize costs.
• Improving internal environment for greater comfort.
• Some shading devices improve the internal or external aesthetics of
building.
• Therefore it is essential to use shading devices.

SHADING FROM EXTERNAL ENVIRONMENT

9. DESIGNING SHADING DEVICES
1. Understand the path of the place
2. Select shading type:
• Horizontal
• Vertical
• Egg-crate
3. Identify category : fixed, adjustable
4. Dimensions : Understanding vertical and horizontal sun angles
