This action launches the Infiltration (Title 24) tab edit view.
Note that the infiltration properties are set by the standard and thus this view simply allows the user to review those properties. The subsequent data required for similariton is passed to the air exchanges tab for each space.
Infiltration (Title 24) tab edit view
· Modeling Method: The method to model infiltration. This field is not user editable.
· Design Flow Rate: The quantity of air infiltrating the space in cfm/ft2.
· Model Coefficients A (none): The constant infiltration coefficient. The coefficients are not user editable.
· Model Coefficients B (1/°F): The infiltration coefficient with units 1/°F.
· Model Coefficients C (hr/mile): The infiltration coefficient with units hr/mile.
· Model Coefficients D (hr2/mile2): The infiltration coefficient with units hr2/mile2.
· Schedule Name*: The user input schedule for infiltration modelling. (Schedules will be defaulted for compliance analysis.)
Example Air Exchanges Tab
It should be noted that for Title 24 2022 the infiltration is now adjusted based inputs for Air Barrier, where this determine the infiltration rates for the buildings conditioned spaces. The air barrier properties for the entire building can be set in the building data dialog – see 4.3.2.1, but this can be overwritten at space via the Title 24 tab in space data:
