methodology
phase 1: building permit research of the current as-is process
phase 2: statistical evaluation of past building permit applications
evaluation of building permits of the last 5 years
requirements determination for the implementation of BIM in the application process
phase 3: information requirements analysis
legal background research and BPMN analysis of the current building permit process research 1

■ 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)

information requirement[definition of set of parameters]
■ successful definition of the information requirements
■ high number of objectifiable and quantifiable items facilitate the introduction
■ high number of sustainability parameters
■ confirmation of requested redundant information
■ high complexity of requirements - data not availabele
