Architects spend a lot of time and efforts trying to solve their design problems. Actually, they just need to look at and learn from the surrounding environment. Nature can achieve not only humans' requirements but also helps to solve the problems, which they make. It could be considered as a life dictionary due to the diversity that exists. That is what the biomimicry science in general aims. One of the practical fields that applies biomimicry science is architecture. Biomimetic architecture aims to redesign multiple sustainable solutions for human's subversion in the built environment. Chameleon is an amazing word that exists in this dictionary. Some of Chameleon species that live in hot arid zones can reduce about 45% of the solar heat gain only by using its skin due to the special physical components called “chromatophores". In this paper, the biomimetic architecture has been introduced. Besides, some famous case studies of architectural buildings that imitate chameleon have been reviewed, analyzed, and classified according to the biomimetic architecture levels.
