The objective of this study was to monitor and record light on/off data in university classrooms equipped with occupancy sensors, compare the data to similar classrooms without occupancy sensors, and ascertain the savings achieved through the use of occupancy sensors. Lighting data were recorded in ten SDSU classrooms during the course of the 1999 Spring Semester. Comparisons were made between rooms with occupancy sensors to those without in an attempt to estimate potential yearly energy savings possible through occupancy sensor installation. The following conclusions were reached regarding the occupancy sensors on campus. a) Due to SDSU's low cost of electricity, and minimal amount of electrical energy savings possible through the use of occupancy sensors, it is not recommended that any additional classrooms be outfitted with occupancy sensors. b) Although the magnitude of actual dollar savings were minor, percent savings possible were comparable to manufacturers recommended savings for occupancy sensors of 30 to 60%. c) Energy savings were calculated on a per square foot of floor space basis, with rooms NFA 125, AD 102, and AE 100 showing the greatest potential for possible occupancy sensor installation. d) Categorizing rooms by type indicated that low expected occupancy rooms and large lecture spaces offered the most promise for future occupancy sensor installation.
