Abstract

Main principles and methods for sunlight tracking in leaves are presented for possible application in shading systems. Plants have developed unique mechanisms for specific climates and locations, where they can determine the amount of exposure for efficient performance. Physiology and geometry are the most significant factors influencing light interception in plants, where leaf distribution, orientation and dynamics influence the exposure to sun radiation. The possibility of developing a shading system for building envelopes, based on the unique shape and structure of plant leaves, which provide them the desired flexibilities induced by sunlight, is discussed and a summary of the main principles is presented. The shade elements have to be more flexible in all directions, where altitude and azimuth angles of the sun have to be considered. An efficient design of shading system for an envelope is achieved when it is adapted to the sun radiation path of each day.
