make components more flexible for usage in districts
--> add parameter "building_name" in components for clear assignment to building
make postprocessing more flexible to generate kpi etc for everry single building and whole districts if there are more than one household in system setup
--> use new parameter "building_name" for iterative calculation of postprocessing
some corrections in kpi calculation in components for clear assignment of outputs in ppdt
