Hello,
I have a scenario with 5 interview rooms that are periodically occupied by 2-3 people each, so they will be multioccupant spaces, and therefore each space would require thermal controls. Could I have fewer than 5 VAV boxes, but put a thermostat in each space and tie multiple thermostats to one VAV box? The controls arrangement would either be a average of the two thermostat requests, or a master-slave arrangement (if one space is occupied, it controls the box output, if not, the other space does).
Thank you,
Mattie

I ran across your inquiry and last year received this guidance from LEED Coach in response to another question about using apps for thermal/lighting controls, but it is relevant:
For example, for an open office area with six individual workstations, if only one FCU or VAV terminal unit is designed to condition the space, there is only one setpoint temperature that the space can be controlled to. Providing all six occupants with software access to adjust that temperature setpoint would not count as six individual thermal controls since the system could not adjust to accommodate more than just one of the control requests.
