Abstract :
With the development of technology, energy consumption has increased globally, especially in the building sector. Therefore, this issue has become one of the main concerns of architects and designers for building design. One of the solutions provided so far to solve this problem is the use of kinetic shading devices for the facade of the building. Devices that follow the sun's path are an effective way to prevent buildings from overheating. They can also be used to regulate the thermal balance of a building. This feature can be used by the shade control system to save energy and reduce peak usage. However, it is challenging to create the best rule-based management systems that simultaneously minimize sun exposure, overheating, and energy consumption. Considering, that nature has always been a source of inspiration for humans, therefore, plants have been chosen as a source of inspiration for the design of kinetic shading devices. Plants, like buildings, are fixed in place by their roots, yet they react to the actions of their surroundings. Therefore, they have the same function as a building. Thus, we suggest a kinetic shading system in this research that uses Saffron movement. The experimental shading device guarantees the most effective performance with a variety of changes, according to a series of simulations by the Ladybug and Honeybee plugins in Rhino6 software. The results indicate that the movement of the shading device in the climate of Shiraz by the movement of the sun can reduce 40% of the sun's radiant energy absorbed by the transparent surface of the southern facade. In addition, the shading device panels in the closed state can reduce the penetration of sunlight into the inner space of the shading device by 50%. This shows the shading device's optimal performance according to Shiraz's climate.
