The port of Bushehr, with its valuable and unique historical texture, completely matches with its unbearable climate conditions. Over hundreds of years, the port has provided an appropriate ground for human life as no air conditioner is needed there. Unfortunately, this valuable old texture has been destroyed inadvertently. New buildings in the port are just superficial copies of the old buildings’ external surfaces, with no attention to their goal, i.e., the provision of thermal comfort for inhabitants. The new buildings are dramatically increasing without considering the historical texture and climate. As a result, the inhabitants have to use air conditioners in most months continuously; hence, there would be an increase in energy consumption and a disruption in climate balance. This study has been conducted to compare the compatibility of such architecture with the climate and its success in providing climate comfort for the inhabitants. According to the information obtained from the study, the old houses built more than 100 years ago using traditional design had better performance in adaptability with climate. Accordingly, the exploitation of traditional instructions and patterns in a new format would largely reduce energy consumption in hot seasons and eliminate the need for heating in cold seasons. In this regard, a huge amount of energy is saved, resulting in less damage to the environment.
