Granular lighting control enables significant energy savings with optimized user confort

In the course of the EnLight project, real-life demonstration pilots of intelligent lighting systems were developed in three locations in Europe. In this article these implementations of the EnLight intelligent lighting system are described. The performance was evaluated by comparing the EnLight installations with a baseline of state-of-the-art lighting systems. The validation concentrates on measuring the energy consumption and illumination at the pilot installation sites. In order to validate the light quality, end user acceptance was evaluated with user surveys. The goal of the EnLight project was to achieve 40% energy reduction compared to today's LED retrofit systems without compromising light quality and user comfort. The main results of the EnLight project are discussed in this article with some considerations for future development.
