Circular Construction Joining Technology

Development of a Selection Methodology for the Designof Architectural Components in the Context of the Circular Economy

The research investigates circular construction by understanding joining technology as an organizational and systemic rather than a purely material decision. It focuses on how the logic of construction systems determines reversibility, disassembly and reuse. Based on this, a selection methodology for systematic planning in architecture is developed, enabling architects to specifically select building systems according to their circular performance and circular strategy.

  • NOW AVAILABLE IN ENGLISH LANGUAGE: BUILDING SORTED BY TYPE

    CIRCULAR CONSTRUCTION METHODS Full landfills, ambitious climate targets: By 2050, the European Union wants to introduce a comprehensive circular economy. For the turnaround in construction to succeed, material resources must be fully reused and recycled. Pure and low-polluting building materials that are used in reversible component connections and are simply joined are the basic prerequisite…

  • Building in closed loops – Lecture by Daniela Schneider on February 24 in Tübingen

    On February 24, Daniela Schneider, gave a lecture on the topic „Circular planning and building: Paths towards a circular economy“ in the Mensa Uhlandstaße in Tübingen. Her speech tackled the big questions of the construction industry: What does responsible use of resources look like? How can we deal with the existing building stock? And how…


  • Online Panel Discussion of FNR

    Daniela Schneider, doctoral student at the KIT Sustainable Building Professorship, will be taking part in an online panel discussion on the topic of „Cycle-efficient timber building system solutions“ at the themed afternoons on timber construction organised by the Agency for Renewable Resources (FNR) on 15 November 2023. More information about the event here.


  • Seminar: Circular component analysis

    The deconstruction friendliness of a construction and the reusability of materials are decisive parameters for circular planning and building. For high-quality recycling and reuse of materials, material layers as well as components must be planned and installed in a detachable way. The aim of the seminar is to determine the qualitative material value of a…
