The main goal of En-ActivETICS project is to develop Energy Activated External Thermal Insulation Composite System for smart building envelope, by combination of traditional low thermal conductivity insulation system ETICS with high heat capacity phase change material (PCM) and flexible photovoltaic (FPV) system generating electrical power. The proposed solution is a new step in the development of building facade technology allowing to achieve a component classified to the group of functional material. The innovative character of the project arises due to the research and technological challenge which is the development of novel, cost and energy effective building component, the examination of its thermal and mechanical properties as well as validation and demonstration of the proposed solution in the relevant environment. The result of the project will be comprehensively tested En-ActivETICS, revealing the capability to adjust its physical properties for better building performance.
