Dormer Settings

When the roof face includes one or more dormers, their parameters can be set. Parameter settings affect all dormers in the roof face.

Wall Thickness

Sets the thickness of the walls in the dormer

Roof Thickness

Sets the thickness of the dormer roof

Style

(Vectorworks Design Series required)

Displays whether the roof face is styled (with the displayed roof style name) or unstyled, and provides the ability to replace a roof style, edit a roof style, or convert a styled roof to unstyled

Wall Clipping

(Vectorworks Design Series required)

Indicates whether the roof face is associated with a set of walls, and provides the ability to associate the roof with a set of walls, or disassociate walls from the roof

Components

(Vectorworks Design Series required)

For unstyled roof faces, opens the Roof Components dialog box to define or edit roof components; see Defining Components for Existing Roofs

Energos

Roofs can participate in Energos energy analysis calculations (see Energos Energy Analysis Module). Vectorworks Architect is required to conduct an energy analysis; however, energy-related parameters can be specified here for informational purposes.

Include in Calculations

When selected, the roof face is eligible to be included in energy calculations, depending on the energy analysis settings for layer/class, element inclusion, and so on.

Boundary Type

Select the type of roof (exterior or foundation).

The system list can be modified; see Specifying System Sets. Editing the system parameters, or adding new ones, allows the exterior and interior RS (surface resistance) values to be specified. If the selected boundary roof calculations are not satisfactory, edit the system list to be extremely specific about the roof surface resistance parameters.

For a finer level of detail about the boundary roof material, click Advanced. The Advanced Settings dialog box opens. Specify advanced settings and then click OK.

●    Exterior Material: For exterior roofs, indicates the general color of the exterior material. The system list can be modified; see Specifying System Sets. The Absorptivity and Emissivity factors are automatically calculated and displayed.

●    Reduction Factor Shading: When the roof is shaded (especially during the summer), enter a shading reduction factor between 0 – 1, where 0 (zero) indicates total shade and 1 indicates no shade.

Calc R-Value/U-Value

Based on the location of the roof within the building (boundary type) and orientation of the heat flow (surface resistance values), the wall R-Value/U-Value is calculated and displayed. This value, along with the area of the roof, is critical for a correct assessment of the building envelope in energy calculations.

Override Calculated Value

Select this option to override the calculated R-Value/U-Value and enter a manual value for the roof instead in Manual R-Value or Manual U-Value
