Some phenomenologists have tried to interpret the cultural differences of identity in a variety of climatic and natural fields in the light of the Genius Loci theory.

Proving the closeness of these two viewpoints in extent and type of the environmental influences on disposition can open a venue for applying the theory of Genius Loci to establish a basis for environmental design in regions with Islamic and

In the first step, the relationships between environmental and cultural characters are explained in four climate-dispositional patterns using Christian Norberg-Schulz's theory of Genius Loci.

Islamic philosophers have considered the types and the extent of climate's influences on disposition and have distinguished different faculties and behavioral affordances for various temperaments and four climates-"hot and dry", "hot and wet", "cold and dry" and "cold and wet". Temperament and the hot and dry climate have shown to be suitable for the moral training of the mankind and assume the character traits of the God. The findings of the present study, the phenomenologist's ideas concerning the character type and environmental/cultural characters in different climates, and the association of the environment and human, have over lapses with the theories of the Islamic philosophers.
