How accurately do the eaves have to be drawn?

The eaves widths used by the program are determined from the distance between the external wall and the roof line.

The eaves width must be drawn as accurately as possible when modelling the shading of windows.

BERS works out the length of the eave and the horizontal offset so no additional data entry is required.


NOTE: When you draw the roof line the eaves width should be made the distance between the outside surface of the external wall and the outside edge of the roof gutter.
