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 )

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