What is solar shading?

Read Time:1 Minute, 33 Second

Solar shading, also known as solar control or solar protection, is an important aspect of architectural design aimed at managing the amount of sunlight allowed into buildings. In a world increasingly conscious of energy efficiency and sustainable living, effective solar shading systems play a vital role in the energy performance of our homes and workplaces.

There are two types of solar shading methods: fixed and dynamic.

Fixed solar shading

Fixed solar shading is like a shield for buildings, placed outside part of the structure. You can see examples such as Brise Soleil at https://alusystems.uk/. The main job of these shading systems is to stop too much heat from the sun getting inside while making sure there’s enough natural light. This helps keep things comfortable inside by preventing annoying glare.

In hot seasons, too much sun can make buildings too warm, and that’s when air-cooling systems are used. External shading is a smart way to handle this. It’s designed to work with the sun’s low position in winter, letting sunlight in, or bouncing light inside.

Dynamic shading

Managing sunlight and heat can be tricky because the sun changes angles. The best way to handle this is by using adjustable shading devices.

Most people use internal blinds or curtains, but external systems can work better. They stop sunlight before it hits the glass. Some shading tools, such as awnings, can be permanent or moveable, giving flexibility. You can operate these tools by using cords or electronically with timers.

Good dynamic shading makes indoor spaces comfortable, prevents glare, controls natural light, and keeps things private.

Types of dynamic solar shading summary:

Internal Blinds: Shades inside the building.
Curtains: Hanging fabric to block sunlight.
Internal Shutters: Panels inside that you can close.
External Shutters: Outside panels for sun control.
Adjustable Awnings and Canopies: Moveable structures outside.
