A traditional light shelf
is a fixed, horizontally mounted plane that can be placed either outside, inside or on both sides of a window to help create reflecting surfaces for more light to enter a house.
A light shelf
is a daylighting system installed on windows, which introduces external natural light into the interiors of a building.
A simple horizontal surface called a light shelf
can help natural light penetrate further into your building, saving you money on artificial lighting and providing occupants with the benefits of daylighting.
One popular way to make a relatively inexpensive light shelf
is to use a heavy-duty, wire storage shelving unit--the big-box-store price is around $70 for a four-shelf unit--and hang shop lights from the undersides of the shelves with wire (see illustration on Page 56).
The authors in their previous work have studied the thermal performance of a combined dynamic shading system consisting of an overhang, a tiltable internal fabric light shelf
and automated bottom-up roller shades.
* Eliminate the clerestory window and its light shelf
, lower the hung ceiling to a flat 9 ft, reducing the building height by 1 ft 4 in.
Given the apparent need for shading, two systems were analyzed--a) automated top-down roller shades (baseline system) and b) a combined dynamic shading system consisting of an overhang, an internal tiltable fabric light shelf
and automated bottom-up roller shades (advanced system).
In fact, studies of day lighting accompanied with light shelf
systems came up that control day light in buildings.
One popular way to make a light shelf
on the cheap k to use a heavy-duty, wire storage shelving unit (the big-box-store price is $65 for a four-shelf unit), and hang shop lights from the undersides of the shelves with wire (see illustration on Page 69).
A light shelf
reflects natural light upwards, complementing the other sources of indirect lighting.
Lighten the Load The InLighten aluminum composite light shelf
from Kawneer/Alcoa is an interior extension of the company's curtain wall system, serving to reflect sunlight further into the interior spaces of the building and bounce light onto the ceiling.
