ضرورت احیای عوامل موثر سنتی بر پایداری اقتصادی و مدیریت هزینه (مطالعه موردی خانه طباطبایی ها)

The application of sustainable development and value engineering concepts in the architecture opens a new discussion called economic sustainability, ecologic architecture, green architecture, and environment architecture; all of which refer to the same concept of environment-friendly architecture. Lack of attention to the foundations for sustainability of traditional architecture of Iran and the diverse factors affecting it has charged us a worn and unstable urban fabric. In this world, along with other scientists the architects have been looking for the new ways to reduce costs and maintain energy as a sensitive duty of them. Regarding the ideas and various theories of scholars on the sustainable development, the main points of focus are: 1. Design for human; 2. Resource saving and economic justification; 3. Renewable materials and resources, and recyclables. The present study is intended to investigate the effective factors in moving toward sustainable development and examines the economic justification of vernacular architecture. Hence, by a review of the references and library documents, it conducts an analysis of Tabatabai's house which is a sample of the traditional architecture of Iran and an appropriate pattern showing the techniques of urban architecture. At the end, some strategies will be provided in line with sustainable development and energy preservation.
