There is urgent need for new building insulation materials or building thermal envelope concepts while it is often economically not feasible to achieve nearly zero energy level for buildings in northern climate. The purpose of this study is to research and create solution for applicable facade system or wall construction itself that has dynamic optical and dynamic properties that will adapt to external weather conditions and will be able to react to different outdoor and indoor temperature and lighting conditions using biomimetic principles avoiding the necessity for additional energy input. The goal of such solution is to gather the energy of Sun in summer for heating in winter.
