This article outlines the interim results of the Project “Young Cities – Developing Energy – Efficient Urban Fabric in the Tehran-Karaj Region”, an Iranian-German Research Initiative In the framework of the research program “Future Megacities” of the German Federal Ministry for Education and Research (BMBF). Lead by the Technische Universität Berlin (TU Berlin) and the Building and Housing Research Centre of Iran (BHRC) the Project has the broad aim of developing, implementing and evaluating technologies, strategies andmethodologies which allow for realizing sustainable and energy-efficient housing settlements in semi-arid regions, explored within the case study of Hashtgerd New Town. This article focuses on the results of the 35 ha Area Pilot Project in Hashtgerd New Town, a unique testing ground for real-life innovations for energy efficiency in the built environment in Iran. After illustrating the aims and the intention of the Young CitiesProject, the article highlights the role and purpose of the Pilot Project and its methodological approach concentrating on the interaction of planning and simulation for energy-efficiency on the urban scale. The presentation of preliminary results of the Pilot Project highlights the complex, integrative and interdisciplinary approach needed to develop sustainable housing quarters. Elements of the 35 ha Pilot Project described in thearticle include compact and mixed-use urban patterns based on climate-sensitive design referencing to traditional Iranian urban form, water-reducing and adapted landscaping and regionally adapted architecture and typologies.The urban design and urban planning features are linked with a range of innovative infrastructure measures such using experimental equations of Iranian code of practice for seismic resistant design of building. Many different techniques exist for estimating dynamic characteristics of structures, based on various kind of experimental or instrumental data, on many different numerical modeling approaches with various rheological behaviors. Their cost varies a lot from one to another; the preliminary information required is not always available; the results provided are more or less quantitative and not always comparable. In this research we will compare the results obtained from the computer analysis with the prevalent software programs in the country (Iran) and the results obtained from the experimental equations of Iranian code of practice for seismic resistant design of building, with those from shaking table tests and microtremore measurements.
