Madlen Kobi participated in the CISBAT “The Built Environment in Transition” Conference organized by the Smart Living Lab (EPFL, Fribourg University and University of Applied Sciences and Architecture Fribourg) which took place on the EPFL campus in Lausanne from September 13-15, 2023. She presented a paper and poster on "Human Energy. An Anthropological Perspective on Labour and Skills in Circular Construction” which she co-authored with Elena Sischarenco and Vanessa Feri. The paper outlines that through the use of human skills and knowledge, energy is mobilised to evaluate, document, dismantle, design, store, transport, and construct with materials. The anthropological approach focuses on people and services instead of treating materials and technologies as independent from the workforce handling them. The results also underline the complexity and diversity of opinions regarding the value of labour in relation to overall project costs.
