Natural Ventilation with Dynamic Façades

In the light of global environmental problems, it is vital for buildings to conserve energy and make use of natural energies. Natural ventilation is one important method for achieving this. In houses, natural ventilation is a very attractive way to control the indoor environment. Compared to this, mid- to high-rise buildings include many closed spaces where windows cannot be opened and internal heat is trapped inside, which increases the cooling load. Based on this situation, consciousness of environmentally friendly buildings and utilization of natural energy becomes high.
