The\ndaylight harvesting system employs light sensors, also known as photocell\nsensors, to detect the prevailing light level in the environment. It then sends\nthe intensity of light received to a controller, which is connected to the\nlighting control system. The control system in turn adjusts the electric lights\nautomatically according to the measured light level.<\/p>\n\n\n\n There\nare two control modes for daylight harvesting; open-loop and closed-loop\ncontrol systems.<\/p>\n\n\n\n In\nan open-loop\ncontrol system<\/strong><\/a>, the photosensor measures only the\nintensity of natural light, thereby adjusting the intensity level of the artificial\nlight to support, offset, or balance the contribution of natural light during\nthe day. <\/p>\n\n\n\n Open-loop\nsensors are typically installed outside the building or near a window or facing\ntowards the source of daylight. Since there is no feedback from the electric\nlighting, this is considered an open-loop.<\/p>\n\n\n\n In a closed-loop\ncontrol system<\/strong><\/a>, the photosensor detects the total amount\nof light intensity, from both natural and electric sources in the environment.\nAnd, based on the detected light intensity level, it adjusts the intensity\nlevel of the artificial light to maintain pre-set ambient light intensities. <\/p>\n\n\n\n Closed-loop\nsensors are typically installed indoors, facing away from the daylight source. <\/p>\n\n\n\n Since\nthe photosensor measures the artificial lighting system\u2019s output, it provides\nfeedback to controller and make further adjustments to maintain the pre-set\nvalue creating a closed loop.<\/p>\n\n\n\n It\nincreases energy savings by dimming or turning Off lights based on the natural\ndaylight entering the space.<\/p>\n\n\n\n It\nhelps to maintain proper light intensity in a space by continuously and automatically\nadjusting lights.<\/p>\n\n\n\n Providing\nright amounts of light to employees helps in maintaining proper circadian\nrhythms that are crucial to good health and adequate sleep besides preventing\nseasonal affective disorders. Letting in natural light to workplaces provide better\nconcentration, creates a positive mood, and drive healthier employee life. <\/p>\n\n\n\n Daylight\nharvesting helps meet Title 24<\/a>\nand ASHRAE 90.1<\/a>\nrequirements using continuous dimming, task tuning, space control, and automatic\/manual\nON\/OFF controls. It achieves the mandatory compliance needs set for building\nconstruction.<\/p>\n\n\n\n Contributing\nto the cause, WiSilica’s sensor devices like WXD2CPLR and WXD2CPLC<\/a> helps in reducing energy consumption in\nenterprises and enables in-house lighting products to be smart and compliant to\nthe energy efficiency standards.<\/p>\n\n\n\n ARIXA<\/a>,\nthe location-aware IoT platform, powers LUMOS<\/a> \u2013\nour Intelligent Wireless Control Solutions to enhance user experience, increase\nlighting comforts, and improve energy efficiency. WiSilica, also offers control devices<\/a> to\nenhance the better experience of daylight harvesting.<\/p>\n\n\n\n WiSilica\nwill continue to delve into daylight harvesting to come up with more energy\nsavings techniques in future posts.

It’s obvious that the natural light is a source of illumination. With ever-increasing demands for energy savings on one side and better recognizing the benefits of natural light for our health on the other side, more businesses are turning to daylight harvesting as means to conserve energy and bring sunlight back into their buildings and workspaces.<\/p>\n![\"Daylight](\"https:\/\/wisilica.com\/company\/wp-content\/uploads\/2020\/05\/4-1024x429.png\")
