Shanashil is a material used in the vernacular architecture of some parts of Iran, especially Bushehr with a hot and humid climate. It is a projected space in building facades which provides cool shaded space. While providing cross-ventilation, view and privacy, the space is protected from harsh sunlight. In a hot and humid climate, cross-ventilation is a necessity for indoor spaces. This requires wide windows on building facades. On the other hand is the privacy for residents, especially for women in the Muslim lifestyle. As a result, such large openings should be screened so that one is able to see from within without being seen from outside. In response to these needs, decorative wood screens were created, providing both visual and thermal comfort. "Shanashil" has also become a decorative material over the time and acquired popularity and prestige. There were always some jars in this space used for the passive cooling of entering air, while providing cool water to drink. Similar material to this is "mashrabiya", which is a prominent feature of Arab architecture. In this article, various features of such material and its typology have been described, and then some of its environmental, cultural, economic, and social aspects of sustainability have been inspected. Most of all, its role in decreasing the hot air temperature using ventilation and evaporative cooling is discussed. Furthermore, the values of luminance have been compared between an ordinary wall and the wall with shanashil. We aim to learn the lessons offered by these superbly vernacular architectural materials and apply them in our current designs. As a result, at the end of the article some solutions for using this material in new buildings have been recommended.
