Modeling Movable Shading Device in Shiraz Climate for Energy Consumption (Inspired by The Sunflower Movement Algorithm)

The existence of intelligent structures for the passive use of energy-regulating systems for energy consumption of buildings in today's era to optimize energy consumption, is one of the main concerns of users of existing buildings. Patterning of kinetic systems in nature is one of the best ways to reduce energy consumption in passive systems that will have the highest efficiency with the least amount of energy consumption. The aim of this research is modeling movable shading device that is compatible with Shiraz climate to optimize energy consumption. Sunflower has been selected as an inspiration source for this research and the plants movement mechanism has been analyzed.

Material & Methodlogy: 

The method of the study is simulation-modeling and kinetic facade performed parametrically in the Grasshopper and analysis of the objectives using the Ladybug plugins. The south facades shading device of a building in the Shiraz climate has been analyzed.   

Due to the use of intelligent materials, the lack of dynamic system in shading device movement, in addition to reduce energy consumption, the amount of radiation receiving during launch hours can be reduced and increased during radiation hours. In research, in addition to analyzing the structure of the shading device during radiation hours, the amount of sunlight entering the window sill was also examined to determine the optimal opening of the shading device during launch hours.

Modeled shading device can be used as a kinetic external sun shading device that can optimize energy consumption compatible with Shiraz climate.
