I re-read your question…
Yes.

Maximum (System Heating design supply air temperature, Zone Heating design supply air temperature) - Room temp = 11

Subject: [EnergyPlus_Support] G3.1.2.8 Design Airflow Rate - supply-air-to-room-air temperature difference
Hi,
I would like to clarify the following doubt:
- the 11°C of supply-air-to-room-air temperature difference specified by Appendix G of ASHRAE 90.1 must be between the room air and sizing:zone or sizing:system?
Thanks,
Leticia
