Poor installation and misaligned supply chain incentives can impact the energy performance and user comfort of External Thermal Insulation Composite System (ETICS) panels. This paper investigates a combined IoT-blockchain solution to create trusted traceability of the process, together with performance-based incentives based on sensor data about the panel state. The system is implemented on the University of Brescia prototype, an experimental test house. The results demonstrate the feasibility of an integrated system of smart contracts, IoT sensors and a digital twin for visualization. The work provides insights into an IoT-blockchain solution applied to a real-world use case for supply chain process improvement.@en
