To achieve climate neutrality by 2050, the EU Council developed the European Green Deal (EGD) which on October 25,2022 was betrayed in a Community directive. The revision of the directive sets up new, more ambitious energy efficiency standards for new and renovated buildings in the EU. The majority of energy losses in buildings are caused by the glazing components on the envelope. Among the many functions of glazing systems, they allow light to enter the interior, can contribute to a building's solar gain, and have traditionally been used to provide natural ventilation for the maintenance of a healthy indoor environment. However, opening several times daily may be still insufficient to provide free air and leads to additional energy losses during this process.
