Investigating the Thermal Behavior of Wind Catcher Room of Rasoulian House in Yazd and Proposing Some Methods for its Improvement Original Article, D21 Kazemi Mand Akbarian M . Journal. Civil Eng. Urban. 4(2): 131-136. 2014 ABSTRACT: Yazd traditional houses are valuable and precious inheritance from our ancestors; therefore, some actions such as changing their application must be taken in order to protect and maintain them. Changing the application of these buildings to some others such as educational, cultural and entertainment centers leads to consumption of nonrenewable energies to prepare thermal comfort for their users. However, the consumption of nonrenewable energies can be minimized using potentialities of these houses. This investigation tries to study thermal behavior of the wind catcher room of Rasoulian house in Yazd which nowadays has been changed into a classroom, for architecture students. In addition to thermal behavior at the traditional status, climatic methods which were implemented at this space are also introduced and analyzed; this study also reviews some other researches in order to find some solutions for improving thermal behavior and minimizing nonrenewable energy consumption. Therefore, some methods are explained to use the potentialities of this building with making minimum changes in the body of the building to prepare thermal comfort for its users.

Investigating Performance of Windscop Installed on Towers in Arid Regions with Using Computational Fluid Dynamics (Case Study: I&M Bank in Nairobi) Hooshmand Aini A., Ahmadnia B and Ahmadnia Bh. Journal. Civil Eng. Urban. 4(1): 77-80. 2014 ABSTRACT:The windscops are designed mainly to direct the wind and fresh air in the buildings. The windscops are able to gather the outside air and direct it into the building. If we want to make a windscops very effective, it shall be able to rotate on all directions. The windscops performance reaches to its top point when they are designed to direct the air for a big hall like an amusement park, etc. In this paper we paid more of our focus on performance analysis for a type of windscops which are installed on tower peaks. At first, we conducted analysis by means of GAMBIT software regarding the geometric model of windscops and the structure analysis, and then we continued to analyze them by means of FLUENT software regarding their pattern of flow. The results of such analyses were demonstrated as velocity on X&Y directions, and flow pattern.

Introduction of Panjeh Ali Bazaar and Ahangarha Bazaar of Yazd of Iran with an Analytical View of Sustainability Concepts Original Article, D8 Kazemi M. and Akbarian M Journal. Civil Eng. Urban. 4(1): 47-53. 2014 ABSTRACT: Today the concept of sustainability is considered as one of the important concepts in the world. In this concept, particular attention is paid to a comprehensive and general approach to the association of the three factors of society, economy and the environment. In some developing countries, environmental and technological aspects are considered regardless of social and economic factors. The concept of sustainability or any other concept which is entered in country literature should be interpreted in accordance with the customs and traditions of the country to make it possible for the community to understand and digest in the Iranian culture. In line with the requirements outlined above, this paper intends to investigate comprehensive view of the ancient Persia toward the concept of sustainability, in Panjeh Ali Bazaar and Ahangarha Bazaar of Yazd, while the buildings are analyzed in terms of social, economic and environmental factors. Thus, the study of Panjeh Ali Bazaar and Ahangarha Bazaar of Yazd indicates that environmental strategies used are associated with social and economic aspects, also that the principles and rules used in its sustainable architectural design are derived in a way so as to be useful and usable for today's world and familiar for Iranian community.
