The concept of Living Lab was originally proposed by Professor William Mitchell from the Massachusetts Institute of Technology (MIT). He believed that Living Lab is a research method that brings laboratory experimental environments into the real-life environments of users for verification, by implementing various complex solutions through perception, prototyping, validation, and improvement in diverse and evolving practical living settings. An extension of Living Lab is Campus as a Living Lab, which means "using the campus as a living laboratory." Participants and implementers of experiments are also members of the campus community. Everyone can contribute ideas, provide feedback, and share results. Organized by National Tsing Hua University, the "NTHU Campus as a Living Lab (NTHU CLL)" primarily involves three key stakeholders on campus: teachers, staff, and students. The aim is to achieve the ultimate goal of "campus sustainability" through stakeholder collaboration, sharing of expertise, drafting experimental plans, and practical implementation. The second NTHU Campus as a Living Lab will be held in 2023, with the goal of posing questions to the university and having students solve them. Through the collaboration of stakeholders, projects submissions, two outcome presentations and evaluations, an exhibition, two workshops, and a sustainable solutions café, the students' sustainable execution capabilities will be enhanced, linking the question-posing units with course teachers. The main activities of this project include project submissions, capacity-building workshops, and outcome sharing. - Project Submissions: NTHU students propose research results and suggestions for sustainable issues faced by the university or suggest solutions for sustainable campus issues they have observed. - Capacity-building Workshops: Through design thinking workshops, students identify the root of problems and propose more effective solutions using design methods. - Outcome Sharing: Through an exhibition in April and outcome sharing in October, students' practical results are showcased, enabling the whole school community to see and facilitating collaboration with partners, stakeholders, and campus members, providing feedback and participation opportunities. This edition has 10 student teams participating with projects that were displayed at the staged exhibition in April. Co-organized by the National Tsing Hua University Regional Innovation Center and the student club "NTHU Green Dots," the exhibition was held during the university's anniversary celebration in the corridor of the Wanhong Library, attracting internal and external visitors to increase project exposure. Visitors were encouraged to provide feedback for each project and were entered into a prize draw to receive eco-friendly potted plants, enhancing interaction and providing valuable and sufficient feedback to the participating teams. The exhibition also employed recyclable hardware display boards, embodying the vision of "sustainable curation." In October, the outcome sharing and evaluation meeting selected five winning teams, including: - "ABLE": Planning Ma Tai Tribe tour itineraries and cultural experience workshops - "International Study Buddy Program Team": Establishing a community for foreign and Taiwanese students to do cultural exchanges and matching different county USR and high school teams with foreign students. - "Where Does the Garbage Go": Investigating and implementing a waste reduction plan at dormitories - "Eggs in the Future Sky": Activating the Chengde space, hosting a spring gathering, and a sustainable sky exhibition - "Glorious Nation": Real-life library and course experience sharing platform - "Sustainability Explorers": Product suggestions and promotional improvements for sustainable smart vending machines.
