When asked to describe their most coveted space, many homeowners are quick to toss out adjectives like light and airy. Natural light is highly desirable light in a home, simply because it makes everything look appealing. Lighting schemes relying on natural light are called daylighting, and builders and architects are getting more requests than ever before to implement it in new construction. Perhaps it's because we spend many of our busy hours sitting at a desk indoors, but we didn't evolve that way. Daylighting keeps us in touch with the outdoors and time of day, and studies have found that people who work in natural light are more productive [source: Mother Earth News]. There are other benefits to natural light as well, such as a savings on electricity if you don't have to turn on lights. But making the best use of natural light is more detailed than throwing open your curtains and embracing the sun's rays. Glare can be an issue if the sun shines directly, or even indirectly, into the room. Heat also needs to be managed, which is usually best accomplished with curtains or shades. Painting a room a light, reflective color can help amp up the natural light, and the best ceiling color to complement the light is the whitest white you can find.
