This paper explores the opportunities for locals’ participation as a tool for the sustainable redevelopment of vacant heritage. It focuses on the Politiebureau Groningen Centrum (The Netherlands) as a case study to apply a novel approach to engage community participation in architectural redesign. It fills the academic gap on participation in heritage building redesign lacking diversity in stakeholder perspectives and overcomes some of the current participatory design tools’ downsides, identified in the previous literature: lack of transparent communication and high requirement for participants. This research employs a combination of methods structured by sets of divergent and convergent phases. Cognitive mapping, semi-structured interviewing, and a 2,5D model game were tested in the research for inquiry and redesign testing, the two key participatory stages. The research outcomes include participants’ perceptions and remembrance of the site for generating redesign scenarios, the common ground in their scenario preferences, and their contrasting attitudes toward the overall material and the specific elements. The 2,5D model game tool turns out effective in transparently delivering the redesign possibilities to participants and lowering the requirements of time, language skill, and learning capacity, thus being easily repeatable for other sites and participants to boost social and community values. Future research recommendations are given on applying the approach to larger samples covering all the minorities to get in-depth knowledge on the community’s collective perspectives in relation to their sociodemographic characteristics and validate the hypothesis on their preferences toward materials and elements.@en

The role of heritage buildings in pursuing a more sustainable built environment has been widely discussed in the last decades, from their importance to cohesive and inclusive communities to their contribution to resources conservation and therefore to reducing materials-related carbon emissions. Norms, policies, standards, and design-aid tools have been developed to encourage urban conservation, but a question persists: why are best practices not yet widely implemented? Decision-making processes have an intrinsic behavioural dimension. Decisions are influenced not only by conscious and rational factors related to heritage buildings and their adaptive reuse, but also by a conjugation of social, psychological, and emotional factors related to the designer. This research uses the “Theory of Planned Behaviour” to analyse architects’ design decisions and reveal the common beliefs, challenges, and opportunities in the conservation of heritage buildings. The results show that while responsibility for the failure in the implementation of conservation is often attributed to third parties, individual attitudes and personal beliefs strongly correlate to the adopted behaviours and, thus, need to be targeted for effective change. Understanding the behavioural dimension of the decision-making process in the adaptive reuse of built heritage is essential to maximize the effect of tools and policies that support actual change toward the growth of a circular economy and a more sustainable future.@en

Purpose: This research presents the development of a Building Passport for Sustainable Conservation (BPSC) as a questionnaire with a set of 23 core indicators, for a baseline assessment of heritage buildings. The aim of this tool is to identify priorities for future interventions, by recognising the contributions of heritage buildings to sustainability that should be preserved and the fragilities that need to be improved. Design/methodology/approach: The BPSC uses a selection of core indicators for sustainability observable on heritage buildings. It was applied to four different case studies of modern heritage in the Netherlands, to verify its applicability and limitations. Findings: The results suggest that this tool has the potential to contribute to an expedite assessment, reaching consensual evaluations of priorities for sustainable conservation, while reducing the time and cost of the process, contributing to support informed redesign decisions. Originality/value: Recently, existing building sustainability assessment (BSA) tools have been adapted and new BSA tools developed for heritage buildings. Some tools target existing buildings, but seldom cover cultural significance and heritage values. Others target the after-redesign situations – aiming at assessing how sustainable the redesign is. Often BSA tools are complex and time-consuming, with extensive indicators and data requirements. The BPSC developed in this research covers the main aspects of sustainability and related heritage values, in a simpler tool for a baseline assessment.

The inclusion of Heritage in the global agenda for sustainable development has contributed to a broader discussion around the interconnection between heritage and sustainability. However, the definitions of both concepts lack consensus. In the last decade, hundreds of definitions of sustainability can be identified in the scientific literature. Often these definitions focus on different dimensions of sustainable development and do not cover the overlapping of social, economic and environmental aspects. The indicators vary according to the main goal and/or specific building under assessment. Moreover, the concept/notion of heritage is understood as a social process based upon definitions and values, which are dynamic and evolve. During the last decades, there is growing attention for the integration of such comprehensive concepts and several frameworks have been developed. However, a systematic definition of the relation between the two concepts is lacking. Some authors even pointed out that the multiple approaches, too specific for each context, lack objectivity and reduce credibility. The main goal of this paper is to contribute to a revised definition of sustainable conservation at the intersection of these two concepts, based on a narrative review of the recent literature and international reference documents, developed by different organisations, such as ICOMOS, the United Nations, and the International Organization for Standardization and the European Committee for Standardization.@en

Despite the recognised importance of built heritage for sustainable development, and the multiple tools, recommendations, guidelines, and policies developed in recent years to support decision-making, good sustainable conservation practices often fail to be implemented. Challenges faced by practitioners often relate to external factors, and there is a gap in the understanding of the role of the nature of the designer and the behavioural dimension of the challenges in implementation. This research applies the Theory of Planned Behaviour (TPB) to verify how a building passport for sustainable conservation (BPSC) impacts design students’ intentions and actual design decisions towards built heritage conservation. This research aims to ascertain the role of the BPSC to affect attitudes, subjective norms, and intentions and ultimately change conservation behaviours. The results show that this tool has a positive contribution to reinforce existing attitudinal beliefs. Still, no significant changes were found in the overall conservation behaviours, suggesting that beliefs hindering implementation may more often be related to aesthetic reasons, creativity and innovation, and program requirements, than with beliefs regarding the sustainable performance of the building. This study demonstrates that using the TPB to analyse design processes in the context of built heritage is an innovative methodological approach that contributes to a deeper understanding of the psychological factors affecting sustainability and built heritage conservation decisions. @en

This research addresses the performance gap between intentions towards a sustainable conservation of built heritage and its actual implementation. Socio-psychological models of human behaviour, such as the theory of planned behaviour (TPB), have been studying this dissonance between intention and behaviour, and allow to recognise latent critical factors. This paper provides a systematic literature review of research publications on the intersection of the topics of human behaviour, heritage, and sustainability. It aims to analyse how the TPB has been used in the field of sustainable conservation of built heritage. The studies are categorised according to the type of heritage, main actors targeted, aims, and methodology. A total of 140 publications were analysed. The results show a recent field of research. In the domain of built heritage conservation, behaviour is commonly addressed as a synonym of performance, targeting the building itself. Most publications relating socio-psychological constructs of behaviour and heritage sustainability can be found in the tourism and hospitality field, focusing on tourists’ and residents’ behaviours. The review shows that practitioners are still absent from the literature. However, research addressing other stakeholders shows that the theoretical framework can play an important role in the implementation of sustainable conservation practices in the built heritage.
