[Bldg-sim] Occupany/Vacancy Sensors for Lighting Power

[Abaza Hussein]

We had these sensors in classrooms and it worked great.

How is it saving more? Are you assuming that a person will enter the space
and will not switch the light ON?

Is anyone aware of a CIR or received approval for using vacancy lighting
sensors on a LEED project.  Meaning the sensor works like an occupancy
sensor but does not turn lights on until the user flips the switch.  Then
the lights automatically turn off after sensing no occupancy for a time.  If
so, what is the approved percentage deduction off of light power density.  I
was assuming an additional 10% over regular occupancy sensors but have been
told the savings could really be a lot higher than that.  Thanks.
