MICROCLIMATE CONTROLLED WITH SLIDING “ECO” PANELS These sliding facade shutters not only provide shade, but also create a microclimate inside the building, forming more pleasant living environment and saving energy. By taking principles, rules and algorithms from nature, and translating them to the design, facade panels are mimicking the leaf structure in order to achieve performance that it has in forming microclimate. Like a leaf, panels control fresh air flow into the building, adapt to the solar exposure thus reducing or maximising insolation if needed, and achieve sufficient structural stiffness with optimal opening ratio and lattice structure. The panels have a slight curvature, with two types: convex and concave, depending on the position and guiding rails. Convex panels are mounted on a rail toward exterior and concave on a rail closer to the windows. All of the panels have sliding mechanism which enables their overlapping, moving, opening and closing. The panel design is inspired by the properties of the leaf: 1. Regulating the airflow and optimising the amount of fresh air 2. Maintaining stiffness and shape 3. Controlling light and temperature by adapting to the environment 4. Changing the interior ambience with adjustable relation between light and shadow Structure of the panel is developed using parametric design, applying natural principles. The algorithm that generates panel’s geometry is a fractal Voronoi diagram which can be found in the structure of the leaf’s cells. Voronoi cells are formed with randomly generated points inside parent geometry. This process is applied in two generations (iterations) with the second one generating cells inside the first one.
