Comparative investigation of thermal treatment and ventilation of Iran's indigenous residential buildings Temperate and humid Climate Case study: Kolbadi House (Sari) and Aghajan Nasab House (Babol)

Since the mid of 70s, there has been urgent need to reduction of energy consumption for heating and cooling buildings around the world. In developing countries, energy consumption to maintain a favorable environment in buildings is the largest portion of total energy demand. In developed countries, the ratio of energy consumption for buildings is larger than that used for other purposes. The world tries to replace fossil energy with renewable energy. On the other hand, the comfort is one of important needs for human at all periods of his life. This comfort has been created or deprived of them in different ways. But comfort in building is the most important issue in this regard. One of important factors to access this issue is a comfort space that becomes available with by creating of favorable environment in terms of temperature and ventilation. In the past, residential buildings were designed, so climate-based that heating, cooling and natural ventilation met all climate requirements. This study considers thermal behaviors of two residential buildings (Kolbadi house and Aghajan Nasab House) by “Ecotect” and “Design Builder” software. By findings analysis, the architectural harmony with climate has been considered. Based on the results, even if these strategies are simple but well thought out to create harmony between building and climate with the lowest energy consumption. Finally, most of the time, these two residential buildings have the temperature of 22 centigrade degrees and from 40 to 42 percent are included in comfort band. It is hoped that these results could be used in the design of modern buildings and they have important role in implementation of architectural harmony with the climate and sustainable architecture.
