"Digital urban mining cadaster as a Smart City Instrument";
Vortrag: SDEWES2021 16th Conference on Sustainable Development of Energy, Water and Environment Systems, Dubrovnik (eingeladen); 10.10.2021 - 15.10.2021.

Building stocks and infrastructures are representing the largest material stock of industrial economies. In order to minimize the use of primary resources, greenhouse gas emissions as well as energy consumption for production of new materials, the "Urban Mining" strategy aims to recycle these urban stocks.
Smart City Vienna Strategy is based on the interplay of the three dimensions of: quality of life, resource conservation and innovation.
The Quality of Life addresses Vienna as the city with the highest quality of life and life satisfaction in the world; focusing on social inclusion in its policy design and administrative activities.
Resource Conservation foresees reduction of its local per capita greenhouse gas emissions by 50% by 2030, and by 85% by 2050 (compared to the baseline year of 2005); reduction its local per capita final energy consumption by 30% by 2030, and by 50% by 2050 (compared to the baseline year of 2005) and finally reducing material footprint of consumption per capita by 30% by 2030, and by 50% by 2050. By 2030 Vienna is an innovation leader; Vienna is Europe's digitalization capital.
For enabling of reduction of material footprint as well as to increase recycling rates detailed knowledge about the composition of building stocks is needed, as well as new methods for assessment, modelling and prediction of upcoming material flows in the future.
New business models to enable sustainable digital planning, construction and deconstruction workflows that facilitate the reuse and recycling of building materials and components along the lifecycle are needed.
How can digital technologies such as Building Information Modelling, GIS, blockchain and smart contracts enable a transparent, recycling-friendly assessment and tracking of building materials and building components along the lifecycle, thus minimizing and reducing emissions and waste?
What requirements must be met for a generation of publicly accessible digital urban mining cadaster as an instrument for a Smart City?
