Developing Sustainable Urban Public Art Installations: Design, Implementation, and Impact Assessment

Thesis Abstract

Urban public art plays a crucial role in shaping civic identity, enhancing aesthetic appeal, and fostering community engagement; however, its sustainability amidst urban growth and environmental challenges remains inadequately addressed. This study aims to develop a comprehensive framework for designing, implementing, and evaluating sustainable urban public art installations, emphasizing environmental, social, and economic sustainability. The specific objectives include identifying key sustainable design principles applicable to urban public art, assessing community perceptions and engagement levels, and evaluating the environmental impact of selected installations. Employing a mixed-methods research design, the study integrates qualitative and quantitative approaches. It involves a survey of 300 residents across three diverse urban districts to gather perceptions of public art's social and aesthetic value, complemented by in-depth semi-structured interviews with 20 urban planners, artists, and local officials to explore user-centered design processes and sustainability considerations. Aesthetic quality and community engagement were quantitatively analyzed using descriptive statistics and factor analysis, while thematic analysis was applied to interview transcripts to extract salient themes related to sustainability and implementation barriers. To assess environmental impacts, life-cycle assessments (LCA) of four recently installed public artworks were conducted, focusing on resource usage, energy consumption, and material longevity, providing comparative insights into sustainable practices. The study anticipates revealing that integrating eco-friendly materials, community participatory processes, and adaptive design strategies significantly enhance sustainability outcomes in urban public art. Key findings are expected to demonstrate positive correlations between community involvement and perceived aesthetic and social benefits, as well as identifying barriers such as resource constraints and technical limitations. Theoretically, the study situates its analysis within the framework of the Theory of Planned Behavior to explain community engagement, and adopts Baum and Hiden’s Triple Bottom Line model to evaluate sustainability performance. The study contributes new knowledge by proposing a multidimensional framework that integrates design principles, community participation models, and environmental assessments, offering practical guidelines for urban policymakers, artists, and planners. The main conclusion underscores that sustainable urban public art is achievable through an interdisciplinary approach that balances aesthetic appeal, social relevance, and environmental responsibility. It recommends establishing standardized guidelines for sustainable materials, fostering participatory design processes, and incorporating lifecycle assessments into project planning to enhance sustainability. Furthermore, the study suggests future research should explore the long-term impacts of sustainable public art on urban resilience and community cohesion, as well as the development of digital tools for monitoring sustainability metrics in real-time. Overall, this research aims to inform best practices in urban public art development, contributing to the evolution of sustainable urban environments that are visually inspiring, socially inclusive, and environmentally responsible.
