A Survey of the Adaptation Rate of Jolfa Housing with the Angle of Radiation

The present paper attempts to study the adaptation rate of Jolfa housing with the angel of radiation. The importance of this topic is due to the recognition and application of environmental and climatic factors that can contribute to development consistency of city. This study, using field observations and applying the information of Iran meteorological organization, indices of method Givoni is performed. However, other information resources are observation and urban designing plans. By analyzing the existing information of Jolfa, it was revealed that in the warm months (July, June) by applying that stuff with high thermal capacity in construction welfare conditions would be provided. But in cold seasons (January, February, March, November, December) needing to mechanical heating is felt and in the rest times of year the welfare conditions are provided. So, in the cold seasons building design approach that emphasizes energy intake. The results of climatic factors and computation techniques applicable law Cosine, monthly thermal needs was evaluated In order to determine the optimal structure in Julfa. In the warm months of year, east and west's direction and in the cold months of year south's direction intake maximum amount of solar energy. However, in according to determined criteria to choose direction of building location, East- west direction is suggested for existing buildings in Jolfa due to in taking low of solar energy in summer and maximum in taking energy in the cold seasons of year.
