The vernacular architecture around the world, have considered many methods for creating better living conditions and welfare measures. Although it was difficult to work in harmony with cruel nature but wherever there is possibility of its use, the vernacular architecture takes advantage of nature. In Iran’s sustainable architecture there are much evidence of Persian architect’s genius and creativity in using nature to their advantage as: Wind catcher in hot and dry areas, Water storage scattered in many parts of Iran, The Yakhchal in depths of land for conservation and preservation of ice and their use in summer. Among them “Kat”, which is specialized in Dezfol and Shushtar of south-west of Iran, was made with certain conditions. In this paper, we studied on how to use “Kat” functional features in modern use in designing green Sidewalk. Based on these functions, a model for Sidewalk was created which will have a thermotical effect in Sidewalk. This model will keep the temperature over Sidewalk 4-5 degree less than other routes in summer.
