In the past, building facades have had large, opaque wall areas and small windows. Today, architects are designing with large, windows and translucent curtainwalls, allowing more natural light to enter the interior space. Designers consider the connection of the inside and outside of a space and the use of daylighting as a way to both connect to the outside world and also for its effect on people as well as building performance.

These changes have increased the needs for solar management and sun shading. There are many materials and systems that are being used to better control and manage solar radiation. Horizontal and vertical sunscreen elements, and sometimes a combination of both, customize each elevation for optimal occupant comfort and building performance. These elements help to shape the aesthetic and identity of the building.
