The cooldown structure works with natural air flow in order to cool the air coming through in the most energy efficient way. To achieve a passive way of cooling we used the Joule-Thomson effect which works with compression and rapid expansion of air and with the

difference of pressure in certain spaces. We developed a shape that enhances the described physical effect and other aerodynamic principles. This project is a starting basis for future product development. We see high potential in the usage of this structure as a second skin facade for a building.
