Besonders mit einem Gebäudeabbruch geht ein enormer Ressourcen- und Energieverlust einher. Diese Arbeit fokussiert den Abbruchprozess am Beispiel einer öffentlichen Verwaltung und analysiert die Möglichkeiten dieser, Kreisläufe von Bauteilen und -materialien in der lokalen Bauwirtschaft zu fördern. \r\nZunächst wurde der IST-Prozess für einen Abbruch von Gebäuden am Beispiel des Kreis Lippe aufgenommen und Schwachstellen für die Wiedereinbringung von Bauteilen und -materialien identifiziert. Danach wurden Best Practice Ansätze von öffentlichen Verwaltungen in Deutschland recherchiert und anschließend dies um den europäischen Raum erweitert. Der letzte Teil der Analyse bezieht sich auf das RE-BUILD-OWL Projekt, mit welchem der Kreis Lippe plante eine Vorreiterrolle in zirkulärem Bauen einzunehmen, und wie die Projektergebnisse die Wiedereinbringung von Bauteilen und -materialien im Rückbauprozess positiv beeinflussen können. \r\nEs hat sich gezeigt, dass sich die Best Practice und die Projektergebnisse positiv auf die Schwachstellen des Abbruchprozesses auswirken können. Konkret wurden für den Kreis Lippe vier Handlungsempfehlungen formuliert. 1. Wissensaufbau: Zwar wurde deutlich, dass bei Einzelpersonen großes Fachwissen beseht, ein Austausch zwischen den Mitarbeitenden bestand jedoch nicht ausreichend. Außerdem besteht auch Bedarf an externen Schulungen geschult/ Sensibilisierung. 2. Digitalisierungsstrategie: Langfristig deutet sich im Bausektor ein Wandel zur Nutzung von Building Information Modeling ab. Es wird empfohlen, diesen Wandel im Kreis Lippe vorzubereiten, um die Mitarbeitenden in dem Wandel mitzunehmen und diese Veränderung proaktiv anzugehen. 3. Aktive lokale Marktgestaltung: Der lokale Markt lässt sich durch die Erhöhung der Nachfrage von verfügbaren Sekundärmaterialien und der Erhöhung des Angebotes von verfügbaren Sekundärmaterialien beeinflussen. Wenn zusätzlich innovative Technologien in der Region gefördert werden, lassen sich langfristig Materialkreisläufe entwickeln. 4. Baustoff- und Materialdistribution: Diese Handlungsempfehlung gilt als Teil der Erhöhung des Sekundärmaterialangebots. Um die Angebotserhöhung der Sekundärbauteile und -materialien zu bewerkstelligen, wurden zwei Optionen vorgeschlagen. Zum einen kann die Fremdleistung der Identifizierung und Distribution eingekauft werden, zum anderen ist eine interne Umsetzung mit Aufbau einer Bauteil- und Materialbörse möglich. Wichtig ist in beiden Schritten, dass vor einem Abbruch ein Audit des Gebäudes und eine Klassifizierung der Bauteile und -materialien auf Wiederverwendbarkeit durchgeführt wird. Eine mögliche Umsetzung der Veränderungen wurden in einer beispielhaften SOLL-Prozess-Darstellung skizziert. \r\nDie Ergebnisse dieser Arbeit zeigen das Potenzial sowie konkrete Schritte auf, die der Kreis Lippe hat, um Bauteile und -materialien in einem Kreislauf zu behalten. Die Best Practice Analyse ist nicht spezifisch für den Kreis Lippe durchgeführt worden, weshalb die Ergebnisse zusätzlich für einen allgemein übertragbaren Erkenntnisgewinn zur Verfügung stehen. Auch andere öffentliche Verwaltungen können anhand der Ergebnisse dieser Arbeit Handlungsschritte ableiten.

Demolition of buildings in particular is associated with an enormous loss of resources and energy. This thesis deals with the role of public administrations, in particular with their demolition process, and analyzes the possibilities of these to promote circular economy of building components and materials in the local construction industry.\r\nFirst, the actual process for demolishing buildings was recorded using the example of the Kreis Lippe and weak points for the reuse of components and materials were identified. This was followed by research into best practice in public administration in Germany and then in Europe. Finally, the last part of the analysis refers to RE-BUILD-OWL, a project with which the Kreis Lippe planned to take a pioneering role in circular construction, and how the project results can positively influence the reuse of components and materials in the deconstruction process.\r\nIt was determined that best practice and the project results can have a positive impact on the weak points. Specifically, four recommendations for action were formulated for the Kreis Lippe.  1. building knowledge: Although it became clear that individuals have a great deal of specialist knowledge, there was not enough exchange between the employees. In addition, external training should be provided as well. 2. digitalization strategy: In the long term, there are signs of a shift towards the use of Building Information Modeling in the construction sector. This change should be prepared in the Kreis Lippe in order to take employees along with the change and proactively tackle this change. 3. active local market design: The local market can be influenced by increasing the demand for available secondary materials and by increasing the supply of available secondary materials. If innovative technologies are also promoted in the region, material cycles can be developed in the long term. 4. construction components and material distribution: This recommendation for action is part of increasing the supply of secondary materials. There are two options for increasing the supply of secondary components and materials. On the one hand, the external service of identification and distribution can be purchased; on the other hand, internal implementation with the establishment of a component and material exchange is possible. In both cases, it is important that an audit of the building and a classification of the components and materials for reusability is carried out before demolition. A possible implementation of the changes was outlined in an exemplary target process diagram.\r\nThe results of this work show the potential and concrete steps that the Kreis Lippe has, to keep components and materials in a cycle. The best practice analysis was not carried out specifically for the Kreis Lippe, which is why the results are also available for a generally transferable gain in knowledge. Other public administrations can also derive action steps from the results of this work.","lang":"eng"}],"ddc":["000"]},{"user_id":"83781","place":"Basel","status":"public","intvolume":"        10","page":"124","department":[{"_id":"DEP6012"}],"title":"Methods of Material and Surface Analysis for the Evaluation of Failure Modes for Electrical Connectors","doi":"https://doi.org/10.3390/technologies10060124","citation":{"bjps":"<b>Kolmer P, Shukla AR and Song J</b> (2022) Methods of Material and Surface Analysis for the Evaluation of Failure Modes for Electrical Connectors. <i>Technologies : open access journal</i> <b>10</b>, 124.","chicago":"Kolmer, Philipp, Abhay Rammurti Shukla, and Jian Song. “Methods of Material and Surface Analysis for the Evaluation of Failure Modes for Electrical Connectors.” <i>Technologies : Open Access Journal</i> 10, no. 6 (2022): 124. <a href=\"https://doi.org/10.3390/technologies10060124\">https://doi.org/10.3390/technologies10060124</a>.","chicago-de":"Kolmer, Philipp, Abhay Rammurti Shukla und Jian Song. 2022.

Many of them are forced to restrict budget and reduce production costs. In addition, the customization of product increases continuously. This results in extension of product variation and reduction of product life cycle. Therefore, the companies need a high flexibility to respond quickly to changes in the market and to customer requirements. Lean thinking, as a powerful tool, has been implemented by many companies in production and manufacturing. In order to avoid waste in lean manufacturing, it is necessary to manage efficiently the material flow. In this study, for a lean material handling system in the lean manufacturing of a company, an in-plant milk-run distribution system is taken into consideration. The system consistsof vehicles, which move periodically in certain routes. The materials are delivered in short intervals from a central storage area to several points of use in the production. By using milk-run in plant, the material handling processes can be standardized and therefore the waste can be eliminated. One additional aim of the study with milk-run distribution for the material provision is to minimize the handling time, which determines directly the personal costs. In order to realize the aim, the work has beendivided into several steps. At first, the production processes, especially the material provision for the production have been analyzed. Secondly, the technological solutions have been analyzed in order to handle different loading units required by different machines in the production. Thirdly, the milk-run distribution for lean production is formulated as an optimization problem with the object of minimizing the number of vehicles and the distance traveled under the constraints of specific time periods, capacity of vehicle and related stations etc. Fourthly, two optimization methods are developed in order to find the optimal solution for the milk-run problem and the performance of different methods is also compared."}],"publication_identifier":{"isbn":["978-3-946856-00-9"]},"oa":"1"}]
