Openings tab in model data under Sloped Roof Windows / Skylights headers
Notes: The settings for roof window dimensions are similar to those for external walls with some important exceptions:
a) The façade settings apply only to sloping roofs. Flat roofs are not covered by this data. To create windows in flat roofs you should draw them at surface level or clone them at building level from other façades. The reason flat roofs do not use the façade mechanism is that there is no top and bottom to set up sills, height vs width etc.
b) Only the 0-None, 4-Fixed width and height
and 5-Fill surface (100%)
façade options are available. There is therefore no way to set up windows using a % glazing (WWR) on roof surfaces.
c) Reveals are not provided for roof surfaces.
There are 3 façade types available for sloped roof surfaces:
The width of the windows including any frame (in m or ft).
The height of the windows including any frame (in m or ft).
The spacing between the each window on the façade (in m or ft). The window spacing is the centre to centre spacing between windows, not the gap between windows.
This is the height of the base of the window from the base of the block (in m or ft).
