In simple words, the illumination of buildings/work space by natural light is called Daylighting. Benefits of Daylighting are not limited only to energy saving, to list a few they are:
§ Daylighting reduces energy/ HVAC/ electricity costs. Energy savings range from 15 to 70 percent.
§ People have natural need for daylight. It has direct impact on well-being and productivity of employees. Office workers perform 6 to 12 percent faster when their indoor work environment offers exposure to daylight.
§ It creates calm and productive environment. It increases concentration and maintain focus on the task at hand.
§ Daylight is an effective stimulant to the human visual system and prevents eyestrain.
§ People perform 10 to 25 percent better mental functions and memory recall when they work in a room with daylight.
§ People with exposure to natural light are less likely to report negative health symptoms hence it decreases number of sick days taken by employees.
§ Students in classrooms with highest daylight were found to progress 20 to 26 percent faster over the period of one year.
§ A positive correlation has been made between use of daylight and retail sales as well.
§ Increased natural light makes the space look bigger and open.
§ Throughout the day, there's variation in light spectrum of natural daylight and it cannot be reconstructed by any other light source. This natural light spectrum has positive effects on us.
§ Sunlight causes our brains to produce a hormone that improves mood, providing energy and making us feel happy. People who get regular exposure to sunlight tend to be more optimistic and sleep better at night.
§ Natural daylight has maximum CRI (Colour Rendering Index) which means it reveals actual colours of objects around us.
The overall long-term savings/ benefits easily make up for initial investment on daylighting. Our innovative Daylight Harvesting Systems can help you get all these benefits. Please feel free to contact us for more details.
