The building sector is responsible for significant global energy consumption and increased greenhouse gas emissions, especially in recent years. The increasing demand for energy for heating and cooling is one of the factors that has contributed to make more impactful this sector. Because of that it became necessary to intervene not only on the renovation of existing buildings with new materials, components, construction processes and the adoption of nearly zero energy buildings but also on the design of the building envelope, which plays an important role in controlling energy and mass flows between the building and the external environment and consequently on the well-being of users.
