The error is generated when the Analysis model is created, i.e. when you enter a 3D Zones view. To do so, make sure that you have a 3D window open on the workspace. On the View menu, point to Display and click Zones. You may need to refresh the 3D Zones view after correcting for this error. On the View menu, click Refresh. Alternatively, use the keyboard shortcut, Ctrl+R.
This error has been generated due to the fact that the dimensions of your window (Height, Width and Level) do not allow it to fit within the dimensions of the designated input wall.
You must consider the height, width and level of your window, in conjunction with the floor and ceiling surface widths of the zone adjacent to the window and the height and width of the input wall.
1. Height: The height of the window itself, including any frame element.
2. Level: The position of the bottom edge of the window with respect to the floor surface (including the floor surface width and frame element). The level cannot be set to less than the floor surface width.
3. Width: The width of the window itself, including any frame element.
The zone adjacent to the window contains both a floor and ceiling surface, each with a defined thickness, or width, as it is referred to within the Edit or New Element dialog.
Suppose your floor surface width is set to 0.05m and your ceiling surface width is 0.1m. If you set your default wall height to 3m, then the useful wall height onto which you can apply a vertical window type is 3m – 0.05m – 0.1m = 2.85m.
The window is not allowed to encroach within the floor or ceiling surface widths. This means that the Level dimension cannot be set to zero if your floor surface width is non-zero (which invariably it will not be).
You should instead enable the Door, rather than the Wall, radio-button or set the Level to equal the floor surface width. It also means that the sum of the Level and Height cannot be such that the top edge of the window is located within the ceiling surface width.
Therefore, the default wall height minus the ceiling surface thickness minus the level (these dimensions are set in the Edit orNew Window dialog) will define the maximum allowable Height, given that the numerical value entered in the Level text-entry box incorporates the floor surface thickness.
How to check floor and ceiling surface widths.
On the Building menu, click Building Elements. On the Building Elements dialog, double-click your floor surface element, e.g. Ground Floor, Upper Floor, etc. Note the width and click OK. The level set for the window must not be less than this value. Double-click the ceiling building element, e.g. Ceiling and again note the width. The sum of the level and height of the window cannot be greater than this value.
How to check the default wall height of the input wall.
On the Building menu, click Floors. Double-click the floor elevation and on the Edit Floor dialog, note the Default Wall Height. This assumes that you have not edited the wall height locally within the 2D Plan view. On the toolbar, click the Select Wallbutton, right-click on your input wall and on the context-menu click Height. On the Wall Heights|Ceiling dialog, verify that the “Use default wall height of current floor” checkbox is enabled.
How to check window dimensions.
On the Building menu, click Windows. Double-click on a window in the list. On the Edit Window dialog you can now check the window dimensions: Width, Height and Level. You should evaluate these in union with the height of the input wall and the ceiling and floor surface widths of the adjacent zone.
To open a 3D Zones view, make sure that you have a 3D window open within the workspace and that it is selected. On the Viewmenu point to Display and then click Zones.
A 3D Zones view will display spaces to which you have applied a zone and any bounded spaces even if unzoned. Remember to refresh the 3D Zones view, either through the View menu (click Refresh) or by using the keyboard shortcut, Ctrl+R.
Note Building Elements adjacent to unzoned areas are not exported to the Building Simulator unless they are also adjacent to a zoned space.
You will not be able to apply a construction to non-exported elements and therefore you will not be able to account for their thermophysical properties. Any heat transfer mechanisms taking place through this “unfinished” section of your building will be ignored by the calculation engine.
Incidentally, a building element between a zoned and unzoned space will be treated by the calculation engine as an adiabatic link.
