Abstract
Aims: Fixed vertical and horizontal canopies that are used in buildings give a low level of clean and inexpensive energy. Therefore, modern technology should use in constructing new buildings in order to have maximum use of this blessing. One of these technologies is kinetic canopies which they can put on the façade. This would result in optimal use of sunlight and also a dynamic design style. The purpose of the current study is to present a kinetic smart shell model inspired by the Mimosa pudica motion algorithm in order to optimize energy consumption.
Materials & Methods: This study is quantitative and simulation-modeling research that modeling of kinetic shell has done in the Rhino 6 software and Grasshopper and climate analysis has performed using the Ladybug plugins. The shell has been analyzed on the south facade of a building in the Shiraz climate.
Findings: In the current study, attempted to create one-degree-angle canopies in each of the horizontal constituents by optimizing the facade to achieve better performance and aesthetic form. The amount of radiation received in this analysis ranges from 0 to 50.16kwh/m2. Finally, a table on the analysis of the kinetic shell energy from 6 to 19 o'clock in August and the climate of Shiraz was presented.
Conclusion: Modeled smart shell can be used as a kinetic canopy that can optimize energy consumption compatable with Shiraz climate.

Abstract
Aim: One of the proposed solutions to reduce energy consumption is to use nature as a source of inspiration. Surveys show that a large part of energy consumption is related to buildings. Considering that the building facade is the boundary between the interior and exterior space, it should be well-designed to reduce energy consumption. One of the solutions is to use an intelligent shading device that controls the entry of daylight in a hot climate.
Method: This research, with its quantitative nature and simulation-modeling research method, has designed a kinetic shell in a building inspired by the movement mechanism of the Rafflesia to control the daylight of the building in the Shiraz climate.
Findings: The research findings indicate that the petals of the Rafflesia performed their opening and closing pattern in five consecutive movements and can act as a kinetic pattern or as a source of inspiration for the movement of the intelligent shading device of the building facade.
Conclusion: In the current research, the petals are considered with triangle geometry, which opens and closes from zero to 45 degrees at the top. In addition, according to the sun’s path from 7 AM to 7 PM, successive steps of opening and closing the flower take place, which can significantly absorb 20% of the radiation and 10% of sunlight hours. Therefore, the movement pattern of the Rafflesia in the hot and dry climate of shiraz has reduced radiation, which shows the optimal performance of the kinetic shading device.
