There are different flavors of occupancy sensors - simple motion, presence (or absence) of natural light, infrared, switch-based, time clock-based, co mbinations of all of these. Using daylighting sensors, coupled with an occupancy sensor, can be extreme ly efficient and provides consistent light levels over a large, deep lab. We have a system that couples daylighting sensors with an occupancy sensor based on infrared technology. When the first person comes into the lab, th ey flip the light switch to tell the system that it's time to "wake up" (th ere's a timeclock to setback lighting levels and ventilation to an afterhou rs mode). Occupant training is important or else the (significant) energy savings aren't realized. For large, multi-bay labs, it's working pretty we ll, once occupants understand the system and how it works. Actually, they think it's pretty cool technology and isn't annoying to them. Careful conversation with users and health and safety helped to provide a s ystem that's working, mostly because the design team really listened. Hope this helps - simple motion detectors alone won't do the trick and your researchers will be squawking for a switch pretty quick. Debbie ----------------- Debbie M.

I'm looking at a set of laboratory drawings where the design team has inserted them, but it's making my flesh crawl a little thinking about t he lights going off when someone's really still. Just wondering if I'm bei ng too paranoid. Kim Kimberly Begley Jeskie, MPH-OSHM Operations Manager Physical Sciences Directorate Oak Ridge National Laboratory (865) 574-4945
