Ventilated facades can help buildings stay cool by reducing the heat from the sun. This study used computer simulations to design facade elements that increase air flow inside the facade, which helps remove heat more efficiently. The results show that using a ventilated facade can save energy compared to a regular facade, especially when there is a lot of sunlight and high air velocity inside the cavity. By improving the design of facade elements, the air velocity inside the cavity can be increased by up to 75%, making the cooling process even more effective.
