Circular building adaptability in adaptive reuse: multiple case studies in the Netherlands

Purpose: The application of circular building adaptability (CBA) in adaptive reuse becomes an effective action for resource efficiency, long-lasting usability of the built environment and the sped-up transition to a circular economy (CE). This paper aims to explore to which extent CBA-related strategies are applied in adaptive reuse projects,...

Data requirements and availabilities for material passports: A digitally enabled framework for improving the circularity of existing buildings

Passports for circularity, e.g., digital product passports and material passports (MPs), have gained recognition as essential policy instruments for the Circular Economy goals of the European Union. Despite the growing number of approaches, there is a lack of knowledge about the data requirements and availabilities to create MPs for existing...

A Conceptual Framework for a Digital Circular Built Environment: The Data Pipeline, Passport Generator and Passport Pool

This article proposes a conceptual model to address the structural holes in data sharing between (and beyond) actors in the circular built environment supply chain and monitoring circular economy progress. Current digital innovations such as material passports and Building Information Modelling applications aim at increasing quality and...

Circular building adaptability and its determinants: A literature review

Purpose: Adaptability is an inherent quality in building circularity, as adaptability can physically facilitate the reversibility of materials in a closed-reversible chain, also called “loops”. Nevertheless, positioning adaptability in circularity-oriented models could overlook some of the contextual considerations that contribute to the...

The technical or biological loop? Economic and environmental performance of circular building components

The construction sector can become more sustainable by applying the Circular Economy concept, which distinguishes two main pathways: substituting materials for biological materials, or optimizing the use or reuse of technical materials. Practitioners sometimes choose one pathway over the other, but knowledge of which of these pathways yields...

A circular economy life cycle costing model (CE-LCC) for building components

The building industry is responsible for the highest resource use, amount of waste and emissions of all industries. The principles of the Circular Economy (CE) could offer an approach to create a more sustainable built environment. For a transition towards a circular built environment, a comprehensive assessment method is needed to support...

Towards a circular built environment: An integral design tool for circular building components

Purpose: The transition to a circular economy in the built environment is key to achieving a resource-effective society. The built environment can be made more circular by applying circular building components. The purpose of this paper is to present a design tool that can support industry in developing circular building components. Design...
