A visit to the Smart Living Lab construction site in Fribourg was carried out as part of the axis “Integrated Design, Architecture and Sustainability (IDEAS)”. This architectural field trip resonates with the issues of sustainability and transition addressed within this teaching and research program.Jointly initiated by the Laboratory of Sustainable Architecture and Technologies (LAST) led by Prof. Emmanuel Rey and the Laboratory of Integrated Performance in Design (LIPID) headed by Prof. Marilyne Andersen, the Integrated Design, Architecture and Sustainability (IDEAS) initiative responds to the objective of promoting a holistic, interdisciplinary, and evaluative approach to sustainable architecture within the Faculty of Architecture, Civil and Environmental Engineering (ENAC), while also strengthening exchanges and synergies between the fields of architecture, civil engineering, and environmental sciences and engineering.The IDEAS program is notably based on the teaching of UE K, the coordination of an interdisciplinary minor dedicated to these issues (IDEAS Minor), and the organization of doctoral seminars and regular events such as the IDEAS Lunches.It was within this framework that the visit to the Smart Living Lab was organized, guided by Dr. Sergi Aguacil Moreno, group leader of Building2050. Located on the blueFACTORY site in Fribourg, this interdisciplinary research center — jointly supported by EPFL, HEIA-FR, and the University of Fribourg — is dedicated to the habitat of the future. Conceived as a multidisciplinary hub and a catalyst for innovation, the building designed by the international architectural firm Behnisch Architekten is intended as a “living laboratory” exploring issues of sustainability, energy efficiency, and user well-being.
