3D modelling of an Asbad (Persian windmill): a link between vernacular architecture and mechanical system with a focus on Nehbandan windmill

Abstract

AbstractAsbads (Persian windmills) present a multifaceted view of using heritage science. These mills are no longer in use due to advances in technology and the advent of new grinding systems. Windmills show perfect harmony between vernacular architecture and mechanical system. This paper aims to review and analyze the mechanism of one of these windmills in Iran and illustrate how these historical buildings can bridge the gaps between these two science branches for better understanding of cultural heritage. To that purpose, a precise 3D modelling of mechanical components and architectural elements is provided based on architectural survey, photographs and sketches. This study addresses how vernacular architecture, with the specific flexibility, can be considered as one of the most useful tools for human beings. Thus, one of the Iranian windmills in Nehbandan was selected through field studies to be modelled. In this construction, local materials such as wood, adobe and stone are used. Findings reveal that windmills and their architectural flexibility are consistent with mechanical components and address environmental needs.
