Utilization Schedules
Utilization schedules designate the percentage of a peak value that should be applied throughout the year. There are thirteen sub-types:
|
|
Each sub-type will be displayed in its applicable section of the project. For example, schedules created under the People sub-type will be displayed in the Internal Loads tab of the Room Properties and in the Internal Loads template.
Adjacent Zone Airflow Utilization Schedules
These schedules are displayed in the Create Building sub-section under the Airflow tab/Airflow transfer section of the Room Properties. It will define the percentage of the room airflow that can be transferred. The default values for the day profile graph are:
