is how eQUEST recommends the modeling of door infiltration
=20
=20
Infiltration Coefficient (Door)
=20
Used to compute infiltration of outside air due to cracks around the =
door frame.
=20
Required if the Infiltration Method is Crack, unused otherwise.
=20
DOE-2 uses the following equation to calculate the infiltration:
=20
infiltration air flow (cfm) =3D (Infiltration Coefficient) =B4 =D6P =B4 =
L
=20
where:
=20
P =3D The pressure differential between the inside and outside air =
(inches of water)
=20
L =3D crack length (ft)
=20
The table below lists typical values for the Infiltration Coefficient, =
based on the size of the crack.
See Infiltration and Natural Ventilation.
=20
DOE-2 Command: DOOR
=20
DOE-2 Keyword: INF-COEF;I-C
=20
Type of Door Infiltration Coefficient (cfm/ft =D6inches of water )
Residential Door (3 ft by 7 ft)=20
closed, with weather stripping 2.4
average use without weather stripping 12
average use with weather stripping 9.8
Office Door (3.5 ft by 7 ft)=20
closed 3.1
open 10% of the time 13.5
open 25% of the time 55
open 50% of the time 153
open 10% of the time, vestibule 9.3
Revolving Door=20
average use 12
Garage or Shipping Room Door=20
no use 6
average use 60
Note: This table is based on a wind speed of 7.5 mph (which corresponds =
to approximately 0.5 inches of water), in a direction normal to the =
wall.

Has anyone ever modeled roll up doors in eQuest, and possibly know the =
best way to compare an insulated door with an uninsulated door?=20
