Regional Priorities for Sustainable Architectural Design in Tehran City Using the LEED Method (District 22, Tehran)

Implementing appropriate design approaches for reaching the goals of sustainable architecture, establishing a residential complex relying on clean energies and considering the climatic characteristics and utilizing different technologies are among the most important needs of the country based on the outlook documents for the next ten years of architecture. Localization or adjusting measuring approaches and then realizing global sustainable architectural standards are of utmost importance in this regard. Therefore, this study has adopted the LEED method for realizing the standards. In measuring the LEED indicators, the most important one is the regional scores indicator which must be extracted and introduced in the process of assessing the regional sustainability priorities. There was no such assessment in District 22, Tehran. Therefore, the main objective of the current study is to achieve the ranking of strategic priorities responsive to the climatic conditions of Tehran so that it can be used as a reference for measuring the success of sustainability projects and similar designs. So, by assessing and investigating the regions which have such scores, including some instances in south California, projects in India, Arizona, and a lot of other regions it was concluded that the regional priority credits are determined based on their sub measures. Accordingly, 50 questionnaires were distributed as a survey among architectural and civil engineers in graduate and doctoral programs. After gathering the questionnaires, using descriptive and inferential statistics in SPSS software application, the credits with the highest frequency percentage were selected as the regional priorities. These priorities were (1) reducing water consumption, (2) renewable energies on site, (3) optimizing energy consumption, (4) optimizing water consumption, (5) waste management, and (6) green energies.
