Baseline-07212020-1 | 2020/07/21 13:07 | System Summary - Page 25 of 25System load and airflow are the coincident peak for constituent zones, as simulated.

Zone loads for cooling and heating are each coincident peak values with respect to constituent rooms without oversizing factors applied.

Zone airflows are design values that include oversizing and other influences as set for individual zones in System Parameters.
