Design flow rate calculation method
|
When on, the design flow rate calculation method
can be changed globally for the selected rooms. The design flow rate
calculation methods can be globally changed to one of the following methods:
Note: Activating and selecting from
options on the
Design flow rate calculation method
New data drop-down automatically enables
the applicable infiltration properties ( Flow rate per
room) making them ready to be globally changed.
-
New data — Used to enter the new Design
flow rate calculation method. The design flow rate calculation method selected
here is the design flow rate calculation method the selected rooms' design will
be globally changed to use when the
Apply button is clicked. Design flow
rate calculation methods appear on the available drop-down list. The same
Design flow rate calculation method drop-down list is enabled when
Restrict changes is checked.
-
Restrict changes — When on, the changes
can be restricted by selecting a design flow rate calculation method to omit
from the global change. The design flow rate calculation method selected here
will be checked for in the selected rooms' existing room design data
properties. If the data check finds the same design flow rate calculation
method, the room is omitted from the global change when the Apply button is
clicked.

Flow rate per room
|
When on, the flow rate per room value can be
changed globally for the selected rooms. Flow rate per room refers to a method
of calculating infiltration flow rates by directly entering the design volume
flow rate for the room.
Flow rate per room options are enabled by selecting
Flow rate per room from the
Design flow rate calculation method
options
-
New data — Used to enter the new flow
rate per room value. The flow rate per room value entered here is the flow rate
per room value the selected rooms' design will be globally changed to when the
Apply button is clicked.
- Restrict
changes — When on, the changes can be restricted by entering a flow
rate per room value to omit from the global change. The flow rate per room
value entered here will be checked for in the selected rooms' existing room
design data properties. If the data check finds the same flow rate per room
value, the room is omitted from the global change when the
Apply button is clicked.
|
Flow rate per area
|
When on, the flow rate per area value can be
changed globally for the selected rooms. Flow rate per area refers to a method
of calculating infiltration flow rates by entering a factor per floor area of
the zone (room floor area is calculated as a portion of the total zone floor
area).
Flow rate per are options are
enabled by selecting
Flow rate per area from the
Design flow rate calculation method
options
-
New data — Used to enter the new flow
rate per area value. The flow rate per area value entered here is the flow rate
per area value the selected rooms' design will be globally changed to when the
Apply button is clicked.
-
Restrict changes — When on, the changes
can be restricted by entering a flow rate per area value to omit from the
global change. The flow rate per area value entered here will be checked for in
the selected rooms' existing room design data properties. If the data check
finds the same flow rate per area value, the room is omitted from the global
change when the
Apply button is clicked.

Flow rate per exterior area
|
When on, the flow rate per exterior area value can
be changed globally for the selected rooms. Flow rate per exterior area refers
to a method of calculating infiltration flow rates by entering a factor per
exterior surface area of the zone.
Flow rate per exterior area
options are enabled by selecting
Flow rate per exterior area from the
Design flow rate calculation method
options
- New data —
Used to enter the new flow rate per exterior area value. The flow rate per
exterior area value entered here is the flow rate per exterior area value the
selected rooms' design will be globally changed to when the
Apply button is clicked.
- Restrict
changes — When on, the changes can be restricted by entering a flow
rate per exterior area value to omit from the global change. The flow rate per
exterior area value entered here will be checked for in the selected rooms'
existing room design data properties. If the data check finds the same flow
rate per exterior area value, the room is omitted from the global change when
the
Apply button is clicked.
|
Flow rate per exterior wall area
|
When on, the flow rate per exterior wall area value
can be changed globally for the selected rooms. Flow rate per exterior wall
area refers to a method of calculating infiltration flow rates by entering a
factor per exterior wall surface area of the zone.
Flow rate per exterior wall area
options are enabled by selecting
Flow rate per exterior wall area from
the
Design flow rate calculation method
options
- New data —
Used to enter the new flow rate per exterior wall area value. The flow rate per
exterior wall area value entered here is the flow rate per exterior wall area
value the selected rooms' design will be globally changed to when the
Apply button is clicked.
-
Restrict changes — When on, the changes
can be restricted by entering a flow rate per exterior wall area value to omit
from the global change. The flow rate per exterior wall area value entered here
will be checked for in the selected rooms' existing room design data
properties. If the data check finds the same flow rate per exterior wall area
value, the room is omitted from the global change when the
Apply button is clicked.

Air changes per hour
|
When on, the air changes per hour value can be
changed globally for the selected rooms. The Air changes per hour refers to a
method of calculating infiltration flow rates by entering the number of air
changes per hour for the infiltration amount.
Air changes per hour options are
enabled by selecting
Air changes per hour from the
Design flow rate calculation method
options
-
New data — Used to enter the new air
changes per hour value. The air changes per hour value entered here is the air
changes per hour value the selected rooms' design will be globally changed to
when the
Apply button is clicked.
- Restrict
changes — When on, the changes can be restricted by entering an air
changes per hour value to omit from the global change. The air changes per hour
value entered here will be checked for in the selected rooms' existing room
design data properties. If the data check finds the same air changes per hour
value, the room is omitted from the global change when the
Apply button is clicked.

Schedule
|
When on, the schedule used to calculate
infiltration can be changed globally for the selected rooms.
- New data —
Used to select a new schedule used to calculate infiltration for the selected
rooms. The schedule selected here is the schedule the selected rooms will be
globally changed to use when the
Apply button is clicked.
