Persian passive techniques of architecture andurban planning is a representation of logicalplanning version for providing all living comfortsbased on natural and low-carbon sources of

energies. It is useful for us to learn from history inthe awareness that settlements, at best, aremanifestations of human creativity. From theirvery origins people have planned their

settlements and there is much that we can learnfrom the ideas and design concepts, skills andeven rules that have been adopted throughouthistory with the conscience.
