A preliminary phase of architectural and urban design processes is a site analysis. It takes deep study of the climatic, geographical, historical, legal, and infrastructural context of a specific site. As a result of analytic process is a graphical sketch, which sets in relation the relevant environmental information with the morphology of the site in terms of parcel, topography, and built environment. These results are starting point for the development of environment-related strategies during the design process.  Many graphical tools for site analysis have been developed to assist designers in this task. Traditional climate-related site analysis tools are: the Sundial, the Sun Path Diagram, the Radiation Square, the Wind Rose, and the Wind Square.
