In this module, we define “daylighting” and explore the technical elements behind how photosensors work. Our experts will discuss the variations in types of photosensors, such as open-loop vs. closed-loop. To wrap up these technical discussions, we will share some case studies of projects that incorporated daylighting strategies.
