Enter a unique name for this object.

Defined at 1 Pa per meter of crack length. Enter the coefficient used in the following equation: Mass Flow Rate = Air Mass Flow Coefficient * (dP)^Air Mass Flow Exponent. Used only when opening (window or door) is closed.

Unit: kg/s-m

Enter the exponent used in the following equation: Mass Flow Rate = Air Mass Flow Coefficient * (dP)^Air Mass Flow Exponent. Used only when opening (window or door) is closed.

Unit: dimensionless

Minimum: 0.5

Maximum: 1.0

Default: 0.65

Select the type of vertical opening: Non-pivoted opening or Horizontally pivoted opening.

Default: NonPivoted

Extra crack length is used for LVO Non-pivoted type with multiple openable parts. Height of pivoting axis is used for LVO Horizontally pivoted type. Specifies window or door characteristics that depend on the LVO type. For Non-pivoted Type (rectangular windows and doors), this field is the extra crack length in meters due to multiple openable parts, if present. Extra here means in addition to the length of the cracks on the top, bottom and sides of the window/door. For Horizontally pivoted Type, this field gives the height of the pivoting axis measured from the bottom of the glazed part of the window (m).

Unit: m
