What is Daylight Harversting Control?

Daylight harversting control, also called constant lux lighting control.

It’s a smart lighting system designed to optimize energy use by automatically adjusting artificial light levels based on the amount of available natural light. This method ensures that spaces maintain a consistent level of illumination (lux level) while minimizing energy consumption by reducing the use of artificial light when sufficient daylight is present. It’s suitable for spaces where it’s important to not distract occupants.

Typical Application: Offices and Corporate Buildings, Educational Institutions etc.

Key Features and Advantages of Daylight Harvesting Control:

The system continuously monitors the available natural daylight and automatically adjusts the artificial lighting to maintain a constant lux level, ensuring optimal lighting conditions at all times. The system can be divided into zones or areas, allowing different sections of a space to be controlled independently. For example, areas near windows may require less artificial light, while interior areas with less natural light will need more artificial lighting.
