2.4.13 Installation of daylighting sensors (on/off)


It is a system that automatically adjusts the quantity of light emitted by the lamp according to the contribution of natural light in the area where it is located. The lamps are connected/disconnected automatically to detect a level of determined brightness (they are turned on at night and turned off during the day).


  • Medium energy savings depending on the natural light contribution in the rooms (up to about 30%)

  • Ability to designate lighting zones

  • Lower maintenance


  • More complicated lighting schematics & installation

  • Longer installation

  • Products require initial calibration

  • May not work properly if installed in an improper location

Economic assessment
