Ventilated facades are building exterior systems designed to improve energy efficiency and indoor comfort. They consist of an outer layer that creates a gap between the facade and the building's insulation. This gap allows air to circulate, helping to regulate temperature and moisture levels. The design of ventilated facades can also enhance the aesthetic appeal of a building. Common materials used include metal, glass, and ceramic, which can be arranged in various patterns. This system not only protects the building from weather elements but also reduces energy consumption by minimizing the need for heating and cooling.
