A room segment is the smallest indivisible element. A room comprises at least one or several adjacent
room segments. A room segment is defined and created only once. Room segments are typically combined
several times to rooms over the course of a building's lifecycle.
20.1.4 Central control functions and grouping
Grouping is used to implement central control functions and to coordinate demand and forced signals from
the various rooms in an entire building, building wing, floor, etc.
Hidden behind the central control functions are system functions, such as operator interventions via
BACnet clients, schedulers, automatic reactions, and data from a weather station.
Central functions influence:
● Room operating mode (occupancy and use in room)
● HVAC control via various setpoint requirements depending on the room operating mode
● HVAC setpoints via a weather-dependent adjustment
● Lighting control
● Shading control (blinds)
Grouping can be used to coordinate demand, operating, and forced signals, that is:
● Request signals for hot water distribution (heating circuit)
● Request signals for chilled water distribution (cooling circuit)
● Record demand, operating, and forced signals for the primary air handling unit
