Building professionals increasingly recognize the benefits of natural daylight-ing to building occupants. Natural light is essential to the healthy functioning of our bodies, including the regulation of melatonin and hormones; people who don't get enough natural light often have trouble sleeping. But windows provide more than natural light; they also connect building occupants to views of nature. The European Solar Shading Organization (ES-SO) guidebook on solar shading claims that workers who are close to an exterior window report 20 to 25 percent fewer major health complaints, while absenteeism falls by 15 percent when access to windows and daylight is provided. A study conducted by the California Energy Commission found that office workers also perform 10 to 25 percent better on mental function and memory tests when provided with the best possible view.
