P&K KFA (VDI 3781 part 4)
With this form the buildings are placed in a coordinate system. The coordinate system is created automatically or determined when adding a map. Buildings can also be comfortably added via the top view.
If this form was opened via the Edit button, selecting a building in the graphic will set the row accordingly. Contrariwise a click into a row will select or indicate the building in the graphic.
Building names are indicated in reports and graphics and serve as references for discharge devices and supply air openings.
Inactive buildings are ignored in calculation and display.
The coordinates of the left lower vertex (anchor point) of the building in m.
Expansion of the gable side of the building in m. For flat roofs arbitrary
Expansion of the building longitudinal side in m.
Rotation of building around the anchor point counterclockwise in degrees.
Height of the building walls in m.
Terrain Height (Z0)
Height of the building base above the coordinate origin in m.
For roof superstructures: reference to the base building. Otherwise "ground".
Height of the ridge above the eaves in m.
Length of ridge in m. For saddle and pitch roofs it corresponds to the building length.
Position of the ridge opposite the front building longitudinal side in m. For symmetrical roofs, it is half the building width.
Height of the upper level of the mansard above the wall in m.
Length of the upper edge of the mansard in m. In the case of a mansard roof, it corresponds to the building length.
Position of the front upper edge of the mansard opposite the front longitudinal side of the building in m. For symmetrical roof, it is half the difference between building and mansard.
Expansion of the upper edge of the mansard on the gable side in m.
Upper Opening Edge
For a simplified and more pessimistic analysis, a value greater than zero can be entered here. Any supply air openings in this building are then ignored and it is always assumed that there is an affected supply air opening with this height.
