A green city center - BAF - Biotope area factor

Calculation examples

Each plot of land can be designed in various ways. In principle, measures that lead to an expansion of the area of vegetation on the ground are given priority. Only then should additional possibilities, such as the replacement of asphalt and concrete with other surfaces, be utilized.

The courtyard is mainly covered with asphalt. There is gravel with grass coverage on the periphery, and the tree stands in a soil bed that measures 1 m².
Calculation: BAF Ground state
140 m² Asphalt	x 0.0 =   0 m²
59 m² gravel with grass coverage	x 0.5 = 30 m²
1 m² open soil	x 1.0 =   1 m²

BAF target = 0.3
