Today we would like to share the advantages of effective daylighting. Below you can discover the astounding benefits of daylighting.
- A proper daylighting plan can reduce energy costs with little or no additional investment in systems.
- A proper daylighting plan can reduce electricity costs.
- A proper daylighting plan can reduce HVAC (heating, ventilation, and air conditioning) costs.
- Energy savings range from 15 to 40 percent (facilitiesnet.com)
- People have a natural attraction and need for daylight.
- Proper daylight can prevent eyestrain in the workplace or school building.
- Proper daylight can help increase concentration and maintain focus on the task at hand.
- While there can be some upfront additional costs, the overall long-term savings will typically make up for any initial dollars spent on daylighting.

- According to a study done by the Sacramento Municipal Utility District, people perform 10 to 25 percent better on tests of mental function and memory recall when they work in a room with daylight and a view, compared to those with no daylight or view.
- People with a view and exposure to natural light are less likely to report negative health symptoms, according to the Sacramento Municipal Utility District.
- The Heschong Mahone Group, Inc., an organization that provides professional consulting services in the field of energy efficiency, found that office workers perform 6 to 12 percent faster when their indoor work environment offers exposure to daylight.
- According to a daylighting and work performance study by the California Energy Commission, exposure to daylight was consistently linked to a higher level of concentration and better short-term memory recall.
- The study by California Energy Commission also concluded that students in classrooms with the highest levels of daylight performed 7 to 18 percent higher on standardized tests.
- Students in classrooms with the highest levels of daylight were found to progress 20 percent faster on math tests and 26 percent faster on reading tests over the course of one year, according to the Heschong Mahone Group.
- A positive correlation has been made between the number of hours of useful daylight and retail sales, according to two separate studies performed by the Heschong Mahone Group and the California Energy Commission.
- Daylight is an effective stimulant to the human visual system and human circadian system.
- Throughout the day, the variation in the light spectrum of natural daylight is unmatched by any constructed light source. The variation of the natural light spectrum positively “affects the performance of chromatic tasks, where the perception of color is an inherent part of the task”, according to L.G. Williams, author of Perception and Psychophysics.
- Windows that provide a view as well as daylight can reduce stress.
