How do we salvage the system?Retrofit with occupancy sensors
⢠Install new passive ceiling sensors to control small groups⢠Recommission system to operate on occupancy instead of
time
Advantages of occupancy based⢠Should have less complaintsâŚif youâre not under the
fixture, you donât need that light⢠New âzonesâ based on sensor coverage area should not
impact future layout changes⢠Less tampering of system since sensors are 20âft in the air⢠Corporate can remotely monitor system through BACnet
