Abstract:
Cities are home to more than half of the world’s population and much of the world’s industry. By 2050, more than 70% of the population – 6.4 billion people – is projected to live in urban areas. Iran has a great opportunity of solar energy and Tehran is located in the semi-arid climate area and due to having more than 280 days of annual sunshine, has a proper annual radiation that makes it appropriate for solar planning. According to this situation this thesis aimed to explain the qualitative and quantitative criteria of a solar efficient neighborhood as a modeling methodology. So the main question of this research is that how a proper solar efficient model could be offered for designing a neighborhood that has been answered by introducing the goal of this project is to provide a model of efficient solar energy.
According to this aim, this thesis has been developed in six chapter. The first chapter contains an overview of the research. Chapter II contains a review of literature and the history of solar modeling at regional, urban and neighborhood scales. Comprehensive energy-efficient models have been proposed in the third chapter that actually are the foundation of solar efficient neighborhood. The fourth chapter has been assigned to recognize the status of the Ayat neighborhood in Narmak, Tehran. In the fifth chapter solar efficient modeling methodology for a neighborhood has been expressed step-by-step, to do this modeling, weaknesses and the inability of previous models is considered to be reviewed, as well as the strengths of previous models upgraded such as attention to the topography of the neighborhood rather than modeling neighborhood on a flat ground and also taking into account the special micro climatic conditions of the region in the Narmak, Tehran. Rest of the chapter, the indicators of daylight, operational energy and potential of photovoltaic devices for urban blocks has been introduced and ultimately implementation of this solar efficient model has been examined in a neighborhood located in Narmak, Using GIS software and Rhino plug-ins such as Grass Hopper and UMI. The Sixth chapter has included the results of the model, answering to the questions of thesis and also expressing some suggestions for future studies.
After applying this model in the neighborhood and assessing of indicators of daylight and operational energy and also potential of photovoltaic devices in 5 urban blocks which has been used extensively during the last three decades in various researches. Results showed that in a constant density linear blocks form is most efficient form regard to micro-climatic conditions and topography of the region.
