Daylighting is the process of using natural light for illumination, minimizing the need for electrical lighting during daylight hours. There are experts who specialize in daylighting design for new buildings, but many daylighting techniques can be used in existing homes, as well.

Even areas with predominantly overcast days can benefit, as daylight on such days still offers adequate illumination and, often, more diffuse and even light than that available in sunnier regions.

Adding windows for more light is a somewhat obvious solution, although this could be pricey. Clerestory windows, located on the upper part of a wall, can bounce natural light off the ceiling, increasing illumination. Skylights could be another good option, particularly in halls or other enclosed spaces that have few, if any, windows.

Discuss with a professional window contractor whether the costs of new window installation justify the potential energy savings. Do be aware that too much sunlight can cause glare, making people close up blinds and turn to artificial light—the opposite of the effect you’d like to achieve.

To direct light coming through existing windows, use louvers or operable blinds. Another option is to install a “light shelf,” a horizontal light-colored or metal shelf, across a window to ricochet light off the ceiling and back into the room. This shelf, normally located about 12 inches from the top of the window for a standard 8-foot ceiling (lower for a high ceiling), may be mounted inside, outside, or in both locations.

Using light-colored paint is another way to enhance the reflection of natural light in a room. Where appropriate, you may select paint with a high reflective value.

The bottom line is this: If you’d like to get more natural light into your home, consider some of the basic daylighting materials and techniques available.
