This paper introduces an evolutionary algorithm methodology to solve facade optimization problems in different climates. The algorithm is based on the improvement of simple Genetic Algorithm (GA). The concept of Adaptive Radiation (AR) is derived from the biological process of adaptation where specific species are evolutionarily adapted to their immediate ecological niches. This algorithm obtains near global optimal solutions in significantly less computation time than simple GA. AR is implemented in three different climates in the United States to demonstrate its robustness and efficiency. Climate adaptive facade design strategies for these climates are illustrated based on the optimization results.
