A Framework for Sustainable Adaptive Reuse of Heritage Buildings

Thesis Abstract

The rapid urbanization and economic development witnessed in recent decades have intensified the pressure on heritage buildings, leading to their neglect, inappropriate modifications, or demolition, thereby threatening cultural identity and sustainable urban environments. This study addresses the critical need for a comprehensive framework that guides the sustainable adaptive reuse of heritage structures, balancing conservation values with modern functional requirements and environmental considerations. The primary aim of this research is to develop an integrated framework that facilitates sustainable adaptive reuse practices, ensuring that heritage buildings remain relevant and environmentally responsible for future generations. To achieve this, the study articulates specific objectives to analyze existing models and theories underpinning heritage conservation and sustainable design, to identify key factors influencing successful adaptive reuse, and to synthesize these insights into a practical framework adaptable across diverse urban contexts. The research employs a mixed-methods design, combining qualitative and quantitative approaches to ensure a comprehensive understanding of the complex dimensions involved in heritage building reuse. The qualitative phase involves desktop review and thematic analysis of 50 case studies from Europe, North America, and Asia, retrieved from academic journals, heritage conservation reports, and urban planning documentation. This phase aims to identify prevalent practices, challenges, and success factors, guided by the theoretical underpinnings of the Conservation Ethics Theory and the Triple Bottom Line Framework. Subsequently, a survey was conducted among 200 architects, conservation specialists, urban planners, and policymakers across 10 cities with notable heritage assets, using structured questionnaires validated through factor analysis. The quantitative data obtained were analyzed using descriptive statistics, correlation analysis, and multiple regression to elucidate relationships among identified variables. The expected findings include a set of core principles and criteria that encapsulate environmental, social, and economic sustainability considerations within adaptive reuse projects. These will inform the development of a validated, practical framework comprising strategic phases, decision-making tools, and evaluation metrics, tailored towards ensuring heritage protection while fostering sustainable urban development. It is anticipated that factors such as stakeholder involvement, climatic adaptation, material conservation, policy alignment, and community engagement significantly influence reuse success, with quantitative analyses supporting the formulation of actionable guidelines. This study contributes novel insights to the discourse on heritage conservation and sustainable urban planning by synthesizing diverse theoretical perspectives into a cohesive, application-oriented framework. It extends existing knowledge by integrating sustainability metrics with conservation ethics, thus bridging gaps between environmentally driven design and heritage preservation. The framework aims to serve as a decision-support tool for practitioners, policymakers, and researchers engaged in heritage building projects, offering a comprehensive strategy for sustainable adaptive reuse that can be customized across different socio-cultural contexts. The main conclusion underscores the importance of adopting an integrated, multidisciplinary approach to heritage reuse that aligns conservation priorities with sustainable development goals. It recommends the institutionalization of the framework within urban planning policies, the promotion of capacity-building initiatives for heritage practitioners, and the establishment of monitoring systems for ongoing evaluation of reuse projects. Additionally, the study advocates for further empirical testing of the framework in diverse geographic and cultural settings to enhance its robustness and scalability. Overall, this research aims to influence policy formulation, improve practice standards, and stimulate sustainable, culturally sensitive urban regeneration initiatives worldwide.
