For this reason, environmental conditions must be evalu- ated for site-specific designs based on sustainability. To design energy-efficient structures, it is essential to evaluate the parameters such as sun, wind, and material in the environment and to create alternatives for the orientation of the buildings. In this context, in this article, based on the climatic conditions of Ankara, the facade features of an office building were determined as a result of optimization simulations, and alternatives were created. The environmental condition data of the model, which was designed using the Rhino–Grasshopper program, were obtained with the Ladybug plug-in. Thanks to the Honeybee plug-in, the position of the sun was determined accord- ing to the day and time zones determined in Ankara, and in this way, alternative facades were pro- duced to the facade design at the location of the building. By using the genetic algorithms, the best of these design alternatives was determined. This optimization method was achieved by detecting the highest peak thanks to frontal optimization based on solar radiation with Rhino–Grasshopper’s Galapagos plug-in. Results show that the partitions on the facade changed according to the posi- tion of the sun. These partitioning alternatives were processed with Galapagos as different alterna- tive inputs, and as a result, facade partitioning with the best possible alternatives emerged.}, number={2}, publisher={Ataturk University}
