Abstract :
The building facade protects the interior space from the outside environment. In addition, most of the energy consumption in the building is aimed at increasing the comfort of the users, and the design of the facade with the correct function can provide the comfort of the users without wasting energy. Due to the necessity of the subject, today the design of kinetic facades to adapt to the surrounding environment of the building has become one of the main concerns of designers. Therefore, the main goal of the research is to design the Convertible Structure of the building facade using natural patterns. Organisms are alive, so, they react to external factors and have many solutions in the field of adaptation. Snapdragon pattern was chosen as a case example in the current research to inspire kinetic mechanism. Plants are very similar to buildings in their function. Both are fixed in place by the root and react to changes in the surrounding environment. Considering that the branches of reducing energy consumption in the building are very wide, therefore, in this research, the approach of daylight control in Shiraz has been chosen. The research method is modeling simulation. In this way, the shading device algorithm was done by the Rhino 6 software and the Grasshopper plugin based on the behavior pattern of the Snapdragon, and finally, the sunlight radiant was analyzed by the Ladybug plugin and the daylight was analyzed by the Honeybee plugin. The results indicate that the shading device designed in the climate of Shiraz, in August from 8:00 am to 4:00 pm on the 10th day, in the case of closed panels, can reduce 75% of the daylight and 64% of the sunlight radiation absorbed by the surface reduced. This causes a 16% decrease in the temperature inside the building.
