Solar Urban Planning and Design

In recent decades, urban population growth, the acceleration of energy consumption and energy price, the increase of public concerns about environmental pollution and the demolition of non-renewable energies, have adverted the attention of different groups to the use of sustainable, available and clean solar energy as a sustainable energy.Specialists like architects and engineers have considered solar energy in designing systems, buildings and equipments. Straggle success achieved in the case, cause the progress of replacing solar systems in buildings and equipments instead of systems consuming unsustainable resources like fossil fuel to be accelerated. But they have not applied coherently yet. In other words, before the enforcement of solar projects in cities, it is necessary to note all the dimensions related to their execution in order to reach their optimum efficiency. The goal that could be attained by long-time and multi dimensional planning.This paper guides the focus of urban and town planning and design on the application of solar energy. That urban planners should consider three aspects of environment, economy and society in three related elements of cities consisting buildings and urban spaces, urban infrastructures and urban land uses to achieve sustainable goals is discussed in this paper.So, after the review of few experiences, the issues and guidelines whose consideration lead to the more efficient solar urban planning and design are outlined.
