Occupancy Sensors Most Recommended Office Lighting Saving Tool
Among new building projects surveyed in the past two years, occupancy sensors were recommended to be installed in 55 percent of applications, according to a recent survey.
While occupancy sensors were the most recommended measure, bi-level switching was the most widely adopted measure.
The Lighting Controls Association authorized ZING Communications Inc. to conduct a survey of a group of about 900 lighting designers, 730 electrical engineers and 530 lighting/energy consultants.
Respondents indicated that occupancy sensors saved them an average 30 percent in lighting energy costs, versus 28 percent for daylighting controls and 23 percent for scheduling (time sweep) controls.
