Vertical devices provide shade based on the bearing angle of the sun. Their effectiveness varies daily, as the sun moves around the horizon.Vertical devices have the ability to block low-angle sun, and consequently the often used on openings facing east or west. Blocking the low angle sun, also blocks views. Adjustable vertical devices can be responsive to the changes in sun angle.
Light shelves are horizontal shading and redirecting devices. They improve the uniformity of natural light in a space by reducing the the level of illumination near the window and redirecting light deeply into space. For best distribution, light shelves should be located as low in a space as possible without causing glare, typically above standing eye level. Improve the effectiveness of light shelves by increasing the ceiling height.
A technique combining both features is a level light shelf with an inward sloping wedge added to the leading edge.This has the effect of pushing high angle sunlight more deeply into space. See sketches below. This feature can be very beneficial, because light shelves typically provide less light when sun is high (summer) than when sun is low (winter).
Light shelves are most effective on the south side as shown below for various climates. Light shelves are not useful for light distribution on north side, but they do not substantially reduce illumination and may make views more comfortable by blocking sky glare.
