Glass is usually recognized as an inert material, meaning that it does not emit volatile organic compounds (VOCs) and is ideal for use in green building.
In addition, glass used as a window or openable facade contributes to natural ventilation. Indeed, depending on occupant needs and climatic scenarios, openable windows can help to provide fresh air entirely via natural ventilation.
