Surface area of the attic ceiling in square meters. Does not have a relation with "length".
Used to calculate total_roof_area and contributes to roof heat loss calculations.
For F280 and EnerGuide: A parameter for heat loss calculations representing generally upward heat flow through a horizontal surface into an unheated space.
See Entity
Length of the attic edge in meters. Not directly used but may be used for geometry validation. Does not have to be relevant to the roof perimeter or area.
For EnerGuide: Used as the insulation compression line.
OptionalroomName of the room this attic is associated with
Provides a general idea of the attic volume. Does not materially impact F280 or EnerGuide.
Structural type of the attic roof
Array of windows installed in the roof/attic space. Assigning windows is not generally recommended for attics.
Represents an attic space in the building structure. Contains the attic's dimensions, type, and any associated roof windows. Generally it is used for unheated attic in which the insulation is on the ceiling line.
