Used to enter a name for the infiltration
component.

Design flow rate calculation method
|
Contains controls used to select a design flow
calculation method for the selected room’s infiltration component. When one is
selected, a corresponding method value field is enabled under the Design flow
rate calculation method control.
- Flow
per room — When selected, the method used is to directly enter the design
volume flow rate for the room. A flow rate must be entered for the Flow
per room control which is enabled by this selection.
- Flow
per area — When selected, the method used is a factor per floor area of the
zone (room floor area is calculated as a portion of the total zone floor area).
A flow rate must be entered for the Flow
per area control which is enabled by this selection.
- Flow
per exterior area — When selected, the method used is a factor per exterior
surface area of the zone. A flow rate must be entered for the Flow
per exterior area control which is enabled by this selection.
- Flow
per exterior wall area — When selected, the method used is a factor per
exterior wall surface area of the zone. A flow rate must be entered for the Flow
per exterior wall area control which is enabled by this selection.
- Air
changes per hour — When selected, the method used is the number of air changes
per hour for the infiltration amount. The infiltration amount must be entered
for the Air changes per hour control which is enabled by this
selection.

Flow per room
|
Used to enter a flow rate when the Flow rate per
room Design flow calculation method is selected. Flow rate per room denotes the
full design volume flow rate which is the maximum amount of infiltration
expected at design conditions.
|
Flow per area
|
Used to enter a flow rate when the Flow per area
Design flow calculation method is selected. The Flow per area is used to
determine the maximum amount of infiltration expected at design conditions for
the specific area occupied by the selected room type within the zone.
|
Flow per exterior area
|
Used to enter a flow rate when the Flow per
exterior area Design flow calculation method is selected. The Flow per exterior
area is used to determine the maximum amount of infiltration expected at design
conditions for all the exterior areas of the selected room type within the
zone.
|
Flow per exterior wall area
|
Used to enter a flow rate when the Flow per
exterior wall area Design flow calculation method is selected. The Flow per
exterior wall area is used to determine the maximum amount of infiltration
expected at design conditions for the exterior wall areas of the selected room
type within the zone.
|
Air changes per hour
|
Used to enter the number of air changes per hour
rate when the Air changes per hour Design flow calculation method is selected.
The Air changes per hour is used to determine the maximum amount of
infiltration expected at design conditions based on the number of times in each
hour the air volume changes due to infiltration.
|
Schedule
|
Used to select an occupancy schedule for the
selected room’s infiltration component.
