CSR:H - Circular Social Residency Informationhub

Situation and Motivation

The EU Green Deal and the introduction of the EU taxonomy present property managers with the challenge of revitalising buildings sustainably. Long utilisation cycles and insufficient information on the composition and quality of building materials - especially in the context of urban mining (Umweltbundesamt, 2021) - make it difficult to plan deconstruction and recycling or reuse processes at an early stage. Particularly in social housing, where considerable material resources are used, there is a lack of comprehensive inventory documentation, while limited personnel and financial capacities make it difficult to strategically record and evaluate the inventory.

Contents and Objectives

The aim of the project is to develop a materials and resources register that can be used nationwide and forms the basis for optimised resource and materials management in the construction industry. The aim is to increase the proportion of recycled materials and reusable components. In addition to the digital recording of masses, quantities, material types and condition assessments, planned refurbishment periods are also recorded and statistical analyses of potential pollutant loads are added. Business and financing models are also being developed to enable manufacturers and trade businesses to develop economically attractive offers for coordinated dismantling, logistics and reprocessing.

Methodological Approach

A multi-stage methodology is being pursued for implementation:

• Digital inventory: By using modern technologies such as laser and LiDAR scanning (also via smartphone), all relevant building and flat data is brought together in a central material database.
• AI-supported material and component analysis: By integrating image data, manual surveys and external data sources, machine learning is used to continuously improve data evaluation and classification.
• Visualisation and platform development: The results are visualised via a user-friendly web map that provides material and product catalogues.
• Business and financing models: Long-term, economically viable offers for dismantling, logistics and recycling are developed on the basis of the material data collected, supported by participatory stakeholder workshops.
• Demonstration and dissemination: The overall process will be tested in selected demonstration projects and the project results will be widely disseminated via workshops, specialist publications and webinars.

Expected Results

The project aims to enable comprehensive, digital recording of the building stock, providing precise data on masses, quantities and condition assessments of the building materials used. This enables early strategic planning of deconstruction and recycling processes, which reduces the ecological footprint in the construction industry and creates economically attractive models for the reuse of materials. Manufacturers and service providers benefit from reliable forecasts and long-term predictable material availability, leading to a viable market for recyclable products. In the long term, the approach supports the achievement of climate targets through a resource-efficient and sustainable construction industry, while at the same time promoting economic sustainability in social housing.
