Towards implementation of circular building components: A longitudinal study on the stakeholder choices in the development of 8 circular building components

Implementing circular building components can contribute to the transition to a circular economy. There are many possible circular design options for building components. Knowledge on which options are feasible to implement remains limited. Existing feasibility studies do not compare multiple circular design options, building components and...

Cooking Up a Circular Kitchen: A Longitudinal Study of Stakeholder Choices in the Development of a Circular Building Component

The built environment can be made more circular by gradually replacing building components with more circular components during construction, renovation, or maintenance. However, many different design options can be seen as circular. Although there is a growing number of studies about circular design options, research on what makes these options...

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...

Circular Housing Retrofit Strategies and Solutions: Towards Modular, Mass-Customised and 'Cyclable' Retrofit Products

The building sector consumes 40 % of resources globally, produces 40 % of global waste and 33 % of CO₂ emissions. Creating a circular built environment is therefore of paramount importance to a sustainable society. The housing stock can be made more circular through circular retrofitting. However, strategies and solutions...
