A Study of Photosensor Configuration and Performance in a Daylighted Classroom Space

Abstract

This paper reports on a computer modeling study to assess the performance of different photosensor-controlled diming systems in a daylighted classroom space. The study addresses different photosensor spatial response functions, ceiling positions relative to the window wall and control algorithms. The results show that each of these features impacts overall performance. In particular, the view that each of these features impacts overall performance. In particular, the view that the photosensor has of the window is inversely related to its ability to properly track the daylight provided and dim the electric lighting system accordingly.
