#space_daylighted_area_window_width(space) ⇒ String

Determines the method used to extend the daylighted area horizontally next to a window. If the method is ‘fixed’, 2 ft is added to the width of each window. If the method is ‘proportional’, a distance equal to half of the head height of the window is added. If the method is ‘none’, no additional width is added.

Returns:

  • (String) —

    returns ‘fixed’ or ‘proportional’

#space_daylighting_control_required?(space, areas) ⇒ Array<Bool>

Determine if the space requires daylighting controls for toplighting, primary sidelighting, and secondary sidelighting. Defaults to false for all types.

Parameters:
