Smart building EnVElope with solaR Energy STorage

In the era of smart technology and self-learning algorithms, the enclosing structures of contemporary traditional buildings still have static properties, they are unable to adapt to the changing indoor and outdoor conditions. Innovative, conceptually new solutions for enclosing structures that can actively participate in the energy balance of a building would be a breakthrough in the field of energy efficiency of buildings. The aim of the study is to create a smart facade for solar energy storage that can capture, store and release solar energy, partially or fully covering the energy needed for heating, thus reducing the building’s impact on climate change. The offered module will combine the most modern technologies – phase change materials, Fresnel lens, advanced insulation materials and dynamic components. The base module developed in previous projects using the biomimetic approach demonstrates the charging/discharging properties. By adding dynamic components to the developed system, the proposed technology will demonstrate the properties of smart technology. The study will combine two methods – experimental tests in an artificial environment and real climatic conditions to test the improved design of the facade module; and mathematical modeling validated by experimental data. The project will gain new scientific insights into future technologies – dynamic building components that provide solar energy storage and their ability to reduce heating demand, thus contributing to the achievement of national and global energy efficiency goals.
