[legal research & precoss analysis]

[GOffice - evaluated data]

■ selective implementation into the building permit process possible

■ poor role of sustainability aspects

■ insufficient consideration of the requirements

■ a modest overall efficiency of the process

■ selective implementation into the building permit process possible

■ poor role of sustainability aspects

■ insufficient consideration of the requirements

■ a modest overall efficiency of the process

■ the status quo differs significantly from the digital technical possibilities available today

■ the dataset reveals a medium processing time, relatively high number of variants

■ the database is incomplete - not fully representative modest data quality

■ poor sustainability aspects (low number of KlimaHaus entries)
