Reusability Assessment of Obsolete Reinforced Concrete Structural Components

Maléna Bastien Masse, Célia Marine Küpfer, Julie Rachel Devènes, Corentin Jean Dominique Fivet

The production of concrete, the most widely used construction material, detrimentally affects the environment. Obsolete reinforced concrete (RC) load-bearing structures, even when still in good condition, are today prematurely crushed and landfilled or rec ...

Decision Framework to Balance Environmental, Technical, Logistical, and Economic Criteria When Designing Structures With Reused Components

Numa Joy Bertola, Célia Marine Küpfer, Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting

The reuse of structural components in new buildings has great potential to reduce the environmental impacts of the construction sector but remains uncommon practice. An obstacle to its wider implementation is the lack of robust assessment methods and decis ...

Scrutinizing the Circular Economy concept applied at the urban level: A contribution based on the analysis of urban circularity indicators, the categorization of Circular Economy interventions, and the identification of factors fostering the adoption of circular innovation

Valeria Superti

Problem. Our current economic systems are deemed unsustainable. Although a global issue, the objective of living in a sustainable society is increasingly an urban challenge, as a rising 50% of the world's population currently dwell in cities. To secure a b ...

Comparison of environmental assessment methods when reusing building components: a case study

Endrit Hoxha, Corentin Jean Dominique Fivet, Catherine Elvire L. De Wolf

The building industry is responsible for 35% of all solid waste in Europe and more than a third of greenhouse gas (GHG) emissions. To address this, applying circular economy principles to the building sector is crucial, for example by reusing building elem ...

Optimum design of low environmental impact structures through component reuse

Jan Friedrich Georg Brütting

Load-bearing systems (structures) in buildings and infrastructure contribute to a significant share of adverse environmental impacts (EI) because of resource- and energy-intensive fabrication. A currently overlooked circular economy strategy to reduce EI i ...

Smooth Power Direction Transition of a Bidirectional LLC Resonant Converter for DC Transformer Applications

Drazen Dujic, Jakub Kucka

The bidirectional LLC resonant converter operated at fixed switching frequency is a preferable candidate for a true dc transformer that does not actively control the power flow. This is due to its naturally stiff voltage ratio regardless of the imposed loa ...

Increasing reuse in learning objects authoring: a case study with the Cacuria tool

Roberto Gerson De Albuquerque Azevedo

Artifacts and best practices reuse as a way of improving educational resources and easing and speeding up the authoring process have been an important theme since the earliest research efforts on Learning Objects (LOs). In such a context, authoring tools t ...

A digital workflow to quantify regenerative urban design in the context of a changing climate

Parag Rastogi, Pietro Florio, Emanuele Naboni

The regenerative approach to design goes beyond limiting the environmental impact of the built environment and towards the enrichment of the ecosystem, adaptation to climate change, and the improvement of human health. This concept is being applied to buil ...

The utility of flow cytometry for potable reuse

Tamar Kohn, Brian Pecson, Krista Rule Wigginton

Protecting public health from pathogens is critical when treating wastewater to drinking water standards (i.e., planned water reuse). Viruses are a principal concern, yet real-time monitoring strategies do not currently measure virus removal through reuse ...

Optimization Formulations for the Design of Low Embodied Energy Structures Made from Reused Elements

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Gennaro Senatore

The building sector is one of the major contributors to material resource consumption, greenhouse gas emission and waste production. Load-bearing systems have a particularly large environmental impact because of their material and energy intensive manufact ...

Optimum Truss Design with Reused Stock Elements

Joseph Jean François Desruelle, Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting, Gennaro Senatore

This paper proposes the application of optimization techniques to design reticular structures made from a stock of reused elements. Still little explored, the reuse of structural components over multiple service lives has the potential to reduce the enviro ...
