[Equest-users] Occupancy Sensors

[Rimes, Christie]

As it states that the reductions can be scheduled I would think that the
LPD doesn't include the reduction due to occupancy sensors. However in
saying this do we need to put in the reduction in the mandatory areas as
it is going to be roughly the same savings applied to the baseline and
proposed building?

The only caveat I would add is that the occupancy sensor requirement is
exempt IF the spaces have multi-scene control. So if a space has several
lighting options then an occupancy sensor is not required. 

 

My question on this point is: If occupancy sensors are required, does
the ASHRAE 90.1 LPD for that space already include the reduction for
occupancy sensors? Or is the percent reduction taken on top of the LPD
values in 90.1?

Section 9.4.1.2 requires occupancy sensors in the following spaces:

1.classrooms (not including shop classrooms, laboratory classrooms, and
preschool through 12th grade class-rooms)
2.conference/meeting rooms
3.employee lunch and break rooms.

Any other areas that have occupancy sensors can be credited in the
energy model.

Hi,
 
I am a little confused as to what areas I can take claim for having
occupancy sensors under ASHRAE 90.1 2007? I have looked at section 9.4.1
however it is not very clear. Any help would be greatly appreciated.
 
Cheers,
