(author)After decades of battling the quantitative and qualitative housing deficits, Latin American countries are seeing new types of challenges in housing.

Dos Santos Vieira Brysch, S.L. (author), Gruis, V.H. (author), Czischke, D.K. (author)Building costs play a significant role in determining the affordability of a housing project, and these depend to a large extent on design choices. This paper is based on the premise that collaborative design processes, or co-design, used in collaborative housing (CH) in Europe reduce building costs and consequently increase the affordability of...journal article 2023

Çetin, Sultan (author), Gruis, V.H. (author), Straub, A. (author)Digital technologies are considered enablers of circular economy implementation in the built environment. Literature mainly focuses on conceptual or review studies examining the role of digital tools (e.g., material passport and building information modelling) to close the material loops. There is a lack of understanding of how digital...journal article 2022

Çetin, Sultan (author), Straub, A. (author), Gruis, V.H. (author)The world is facing an alarming housing crisis. The challenge for the construction industry is to find sustainable ways to meet this growing housing demand. The concept of Circular Economy could be an alternative approach as it aims to regenerate, narrow, slow, and close resources loops. Digital technologies are seen as enablers to implementing...conference paper 2022

Jansen, B. (author), van Stijn, A. (author), Gruis, V.H. (author), van Bortel, G.A. (author)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...journal article 2022

(author)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...journal article 2022

Hamida, M.B. (author), Jylhä, T.E. (author), Remøy, H.T. (author), Gruis, V.H. (author)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...journal article 2022

Çetin, Sultan (author), Gruis, V.H. (author), Straub, A. (author)The concept of Circular Economy (CE) and its application in the built environment is an emerging research field. Scholars approach CE from various perspectives covering a wide range of topics from material innovation to city-scale application. However, there is little research on CE implementation in housing stock, particularly that which is...journal article 2021
