Design Fundamentals in the Hot and Humid Climate of Iran: The Case of Khoramshahr

Building design based on principles of architecture in harmony with the climate of each region, in addition to creating thermal comfort in building interiors, reduces fuel consumption and more important it will demonstrate a clean and green environment. This issue becomes more intense in some geological areas like Khoramshahr in Iran, which has a warm, tropical and critical climate, since if this issue is not taking into account, using air conditioning utilities would be necessary in most periods of the year. According to the studies, buildings in harmony with the climate of Khorramshahr will be able to adjust the thermal conditions of their interiors naturally to the human comfort level in 82 % of cases during a year. In such a building, only in 18% of cases during a year, using mechanical systems for cooling the internal spaces is essential. The main problem in this climate is cooling the interior spaces in hot season but in winter these spaces can be kept warm at the level of comfort by using passive or active solar energy or by using simple thermal devices in some situations. This all issues give a good answer to the rules of green architecture which they were carried out by traditional architects as well. Research method of this paper is mainly descriptive and analytical which study the traditional housing of Khorramshahr has been considered for achieving climatic design principles. The results of the studies show that the most problematic issue in this climate is the dry and dusty wind in summer. Since in winter, using solar cooling systems perform a situation that restricts unfavorable climatic factors. In this paper both of above mentioned issues were solved through some guidelines in the area of green architecture.
