Urban Mining - anthropogenic resource Cadastre: Estimation of material stocks in buildings using INSPIRE data specification for buildings (BU)

(Submission #405)


The building sector is known to have the largest inventory of materials in industrialized societies. To increase resource reuse and recycling from the anthropogenic stock is one of the key strategy elements of the European Union resource policy. Hence, the idea to establish a building resource inventory is not new; a systematic and transferable approach is still missing. In strategic considerations, it is important what resources are bound within current stock. It is of interest of both, economically and ecologically for modern societies. A material inventory (in matter of compositions) and their specific location can help to define regional strategies to become more resource import independent and strengthen sustainable development. This approach of discovering, recovering and reusing resources from the anthropogenic stock is summarized under the concept of ‘Urban Mining’. However, the re- and upcycling of materials from the building stock is still missing information of kind, quantity and especially spatial distribution. To assess regional material stocks, following a bottom-up approach, two perspectives need to be combined: the “stock-taking” and “spatial” perspective. The “stock-taking perspective” gathers information from investigations of single buildings, so called reference building-inventories. In contrast, the “spatial perspective” should be based on existing spatial data. Currently both perspectives are using different typologies (e.g. building definitions) and even more important data models. The harmonized INSPIRE data-model for buildings can be the key element for area-wide, transferable as well as comparable stock estimations. The gross volume, calculated from 3D building data is used as conversion factor to transfer resource parameters (kg/m³) from reference buildings into the area. Bringing together the bottom-up Urban Mining approach and a harmonized data model for buildings, a common framework for building stock estimation within Europe could be initiated. This presentation will showcase how to establish an ‘Urban Mining Cadastre’ using INSPIRE building models. Based on a feasibility study in the Rhine-Main region (Germany) it can be demonstrated how the INSPIRE model can be used and where there is a need for adjustment to fulfill all criteria required (geometric / semantic). Especially in the sector of non-residential buildings current code-lists need to be extended. The given possibility to store specific individual code-lists in a registry (like GDI-DE Registry) will be discussed. As a result, this use-case will show how INSPIRE datasets can provide a projection of the spatial distribution as well as the temporal availability for the accumulated materials within a region.
