Abstract
This paper explores the role of sustainability into an environmental and historical IT-supported project, named Gaia Vesteralen. The project utilises spatial AR/projection mapping technology to promote environmental and cultural awareness. We applied a qualitative research approach to explore sustainability aspects of the project. Sustainability Analysis Framework (SusAF) is a widely used approach to sustainability design that revealed issues related to projection mapping technology. The results suggest that sustainability is a multifaceted concept, and the project aims to balance different dimensions of sustainability while delivering engaging, immersive experiences to a diverse museum audience. The complexities of integrating sustainability into technologically driven initiatives are carefully balanced with goals of environmental, social, and economic responsibility. The findings suggest that the Gaia Vesteralen project represents an aspiring attempt to integrate sustainability into a technology-driven exhibition.
