Architects Today Still Very Often Create Traditional 2d Plans In The Early Planning Phase, Which Form The Basis For Discussions With Investors, Clients And Engineers. The Designs Are Often Difficult To Understand For Non-Experts And Design Variants Can Only Be Compared With Great Effort. The Use Of BIM Models Simplifies Both Communication And The Actual Creation Through The Use Of Parametric Modeling Approaches. Even Though A Building Project Always Has Very Individual Characteristics, It Makes Sense To Take Experience From Other Projects As A Basis For The Design. Therefore, It May Be That Suitable Floor Plans Of Similar Buildings Already Exist, Which Are A Good Basis For Variant Studies In Early Design Phases. A Challenge Is To Be Able To Access The Experience Of Other Architects. Currently, This Information Is Not Available And Is Difficult To Transfer From One Project To The Next. This Paper Outlines A Solution For A BIM-Based Variant Retrieval Of A Building Design In Early Design Phases Using Case Based Reasoning (CBR) And Pattern Matching (PM). On The One Hand, This Offers The Possibility To Learn From Old Mistakes, And On The Other Hand, It Enables The Quick Selection Of Suitable Variants For A Building From A Diverse Pool Of Variants.
