Anybody know a good way to handle occupancy sensors in rooms?

Thanks,

I have done this in the past with a multiplier, say a 10% reduction with
occupancy sensor vs. without. Here's an example where I've used a global
parameter to use 90% of the baseline values. The #pa("Light OS Occ
Factor") pulls the variable Light OS Occ Factor from the global
parameter.

\$ ---------------------------------------------------------

\$ Global Parameters

\$ ---------------------------------------------------------

PARAMETER

"Light OS Occ Factor" = 0.9 ..

\$ ---------------------------------------------------------

\$ Day Schedules

\$ ---------------------------------------------------------

"Lt OS WD" = DAY-SCHEDULE-PD

TYPE = FRACTION

VALUES = ( 0, &D, &D, &D, &D, {.1*#pa("Light OS Occ
Factor")},

&D, {.3*#pa("Light OS Occ Factor")},

{.9*#pa("Light OS Occ Factor")}, &D, &D, &D, &D, &D, &D, &D,
&D,

{.5*#pa("Light OS Occ Factor")}, {.3*#pa("Light OS Occ
Factor")},

&D, {.2*#pa("Light OS Occ Factor")}, &D,

{.1*#pa("Light OS Occ Factor")}, 0 )

..

"Lt OS Sat" = DAY-SCHEDULE-PD

TYPE = FRACTION

VALUES = ( 0, &D, &D, &D, &D, &D,

{.1*#pa("Light OS Occ Factor")}, &D,

{.3*#pa("Light OS Occ Factor")}, &D, &D, &D,

{.15*#pa("Light OS Occ Factor")}, &D, &D, &D, &D, 0 )
