External shading system can be defined as external solid or perforated shaded devices that are mounted outside the building. These shades that are mainly in the form panels are static and movable. A reflective film can be applied for glazing and fritting technique can be used for architectural glazing with applied opaque pattern. The shades generally deflect sun rays, thereby decreasing exposure of indoor space to sun rays.
The few advantages of shade blinds in Melbourne are:
- Reduces the need of room cooling systems: If the indoors are fitted with shading systems, then they would be less exposed to sun rays, there by the room would be cooler and the requirement of cooling systems would be very less.
- Glazing effect because of reflective film: The reflective film that is fixed on windows can be used for glazing effect and provides a friendlier environment for indoors.
- Saves energy: The shading systems reduce the need of cooling systems, so it saves energy. The effectiveness of the shading is dependent on building form, shade design and orientation of glazing.
- Reduced cost: Energy for cooling indoors is saved by screens, this helps in saving money on energy. Few models of the screens come in automated model, which may need little energy, but would be much less than energy required for cooling systems.
- Easy to use: Most of the systems are automated and can be operated with a button or by using a hand roller. These screens would not require you to go out and make the changes to the screen.
- Improvement opportunities: External shading devices would provide a modified look to the indoor and outdoor premises of a building. Fixing of a solar film does not require any planning approval unless it alters appearance of the building or the building is under conservation area.
All type of buildings can be attached with shading systems. External shading systems are better than internal systems as they are more effective and provide a lot of comfort if positioned effectively.
