Block that outputs the zone group status
Information
This sequence sums up the zone level status calculation to find the outputs that are
needed to define the zone group operation mode.
It requires following inputs from zone lelvel calculation:
-
zonOcc
: if the zone-level local override switch indicates the zone is
occupied,
-
u1Occ
: if the zone is occupied according to its occupancy schedule,
-
tNexOcc
: time to next occupied period,
-
uCooTim
: required cooldown time,
-
uWarTim
: required warm-up time,
-
u1OccHeaHig
: if the zone temperature is lower than the occupied
heating setpoint,
-
u1HigOccCoo
: if the zone temperature is higher than the occupied
cooling setpoint,
-
u1UnoHeaHig
: if the zone temperature is lower than the unoccupied
heating setpoint,
-
THeaSetOff
: zone unoccupied heating setpoint,
-
u1EndSetBac
: if the zone could end the setback mode,
-
u1HigUnoCoo
: if the zone temperature is higher than its unoccupied
cooling setpoint,
-
TCooSetOff
: zone unoccupied cooling setpoint,
-
u1EndSetUp
: if the zone could end the setup mode,
-
TZon
: zone temperature,
-
uWin
: True when the window is open, false when the window is close
or the zone does not have window status sensor.
The sequence gives following outputs for zone group level calculation:
-
uGroOcc
: the zone group should be in occupied mode when there is any
zone becoming occupied according its schedule or due to the local override,
-
nexOcc
: the shortest time to the next occupied period among all the
zones in the group,
-
yCooTim
: longest cooldown time,
-
yWarTim
: longest warm-up time,
-
yOccHeaHig
: if there is zone with temperature being lower than the
occupied heating setpoint, so the group could be in the warm-up mode,
-
yHigOccCoo
: if there is zone with temperature being higher than the
occupied cooling setpoint, so the group could be in the cooldown mode,
-
yColZon
: total number of zones that the temperature is lower than the
unoccupied heating setpoint,
-
ySetBac
: check if the group could be into setback mode due to that
the average zone temperature is lower than the average unoccupied heating setpoint,
-
yEndSetBac
: check if the group should end setback mode due to that
all the zone temperature are above their unoccupied heating setpoint by a limited
value,
-
yHotZon
: total number of zones that the temperature is higher than the
unoccupied cooling setpoint,
-
ySetUp
: check if the group could be into setup mode due to that
the average zone temperature is higher than the average unoccupied cooling setpoint,
-
yEndSetUp
: check if the group should end setup mode due to that
all the zone temperature are below their unoccupied cooling setpoint by a limited
value,
-
TZonMax
: maximum zone temperature in the zone group,
-
TZonMin
: minimum zone temperature in the zone group,
-
yOpeWin
: total number of opening windows.

Block that outputs the operation mode
Information
This block outputs VAV system operating mode. It is implemented according to
ASHRAE guideline G36, section 5.4.3, section 5.4.4, section 5.4.5 and section 5.4.6.
Note that, from the user's point of view, schedules can be a set for individual zones,
or they can be set for an entire zone group, depending on how the user interface is
implemented. From the point of view of the BAS, individual zone schedules are
superimposed to create a zone-group schedule, which then drives system behavior.
-
All zones in each zone group shall be in the same zone-group operating mode. If one
zone in a zone group is placed in any zone-group operating mode other than unoccupied
mode (due to override, sequence logic, or scheduled occupancy), all zones in that
group shall enter that mode.
-
A zone group may be in only one mode at a given time.
Each zone group shall have the operating modes shown below.
Occupied Mode
A zone group is in the occupied mode when
occupancy input u1Occ
is true. This input shall be retrieved from
other sequences that specifies occupancy variation and time remaining to the
next occupied period tNexOcc
. A zone group could be in the occupied
mode when any of the following is true:
-
The time of day is between the zone group's scheduled occupied start and stop times.
-
The schedules have been overriden by the occupant override system.
-
Any zone local override timer is nonzero.
Warm-up Mode
Warm-up mode shall start based on the zone with the longest calculated warm-up
time maxWarUpTim
requirement, but no earlier than 3 hours
(preWarCooTim
) before the start of the scheduled occupied period,
and shall end at the scheduled occupied start time. Zones where the window switch
indicates that a window is open shall be ignored. Note that for each zone,
the optimal warm-up time shall be obtained from an Optimal Start sequences,
computed in a separate block. The figure below shows the sequence.
Cooldown Mode
Cooldown mode shall start based on the zone with the longest calculated
cooldown time maxCooDowTim
requirement, but no earlier than 3 hours
(preWarCooTim
) before the start of the scheduled occupied period,
and shall end at the scheduled occupied start time. Zones where the window switch
indicates that a window is open shall be ignored. Note that for each zone,
the optimal cooldown time shall be obtained from an Optimal Start sequences,
computed in a separate block.
Setback Mode
During unoccupied mode, if any 5 zones (or all zones, if fewer than 5)
in the zone group fall below their unoccupied heating setpoints, or if the average
zone temperature of the zone group falls below the average unoccupied heating setpoint
(uSetBac
becomes true), the zone group shall enter setback mode until
all spaces in the zone group are 1 °C (2 °F) above their
unoccupied setpoints (uEndSetBac
becomes true).
Freeze Protection Setback Mode
During unoccupied Mode, if any single zone falls below 4 °C
(40 °F), the zone group shall enter setback mode until all zones
are above 7 °C (45 °F), and a Level 3 alarm shall be set.
Setup Mode
During unoccupied mode, if any 5 zones (or all zones, if fewer than 5)
in the zone group rise above their unoccupied cooling setpoints, or if the average
zone temperature of the zone group rises above the average unoccupied cooling setpoint
(uSetUp
becomes true), the zone group shall enter setup mode until
all spaces in the zone group are 1 °C (2 °F) below their
unoccupied setpoints. Zones where the window switch indicates that a window is
open shall be ignored.
Unoccupied Mode
Unoccupied mode shall be active if the zone group is not in any other mode.

Compute the AHU operating mode from the group operating mode
Information
This sequence specifies the operation mode of a AHU system, which may serve
multiple zone group. It is implemented according
to Section 5.15.1 of ASHRAE Guideline G36, May 2020.
When zone group served by an air-handling system are in different modes, the following
hierarchy applies (highest one sets AHU mode):
-
Occupied mode
-
Cooldown mode
-
Setup mode
-
Warm-up mode
-
Setback mode
-
Freeze protection setback mode
-
Unoccupied mode
See the operation mode enumeration in
Buildings.Controls.OBC.ASHRAE.G36.Types.OperationModes for the detailed
description.
