There has long been a concern that evaluating building thermal performance on the basis of energy loads is inappropriate to achieve overall energy efficiency of houses, particularly passive houses, in temperate climates. Passive buildings designed to be free running may achieve better results in an appropriate evaluation system. The main objective of this study is to investigate differences between thermal performances of houses in different operation modes. The paper illustrates a relationship between indicators of building performance in free running and conditioned modes. Simulation is used to compare the predicted performances of conditioned and free running houses, respectively on the basis of annual energy requirements (MJ/m2) and Degree Discomfort Hours (DDH) in temperate climate of Babolsar, Iran. Despite a strong relationship between these two indicators, some significant differences become clear leading to a discussion of the persistent technical problems and issues, which are encountered when attempting to optimize an efficient architectural design. The result of this study persuades the architects to pay more attention to the process of building energy efficient design regarding to the building operation mod. Application of this result in the building labelling system can promote the passive building design which is an important step to achieve objectives of sustainable development.

In new issues of durable architecture, it is tried to decrease negative effects of new architecture on environment. What is perfectly obvious is making the elements homogenous to their climatic function which was the art of our antecedents. Implementing the windward construction technique, our antecedents have well used the raw and uncontrolled flows of wind. They handled the wind and made it mild, remove the dust and created mild air-conditioning which represents the past environmental stability of Iranian architecture. Using the windward had been conventional in Iran since many years ago. Without any dependence on any kind of energy and without exploiting establishment appliances, it provides the coldness of residential places. This is the same issue on creating stability in environments where humans live in. In this research, the capabilities and limitations to use windward in salt desert's cities of Iran during today's age in were assessed to achieve some criteria quantitatively and qualitatively to enhance the windward and to provide the necessary ground for more efficient use of it. This research is of descriptive- analytical kind. Statistical population of this research includes university professors and architecture authorities in Iran. 30 persons of them were questioned directly. After survey data collection through the questionnaire, the relationships between research variables were tested by implementing swot technique. The obtained results suggest a windward in order to solve the weaknesses of previous air traps parallel to today's need. It indicates that giving the efficiency again to the windward’s by creating some changes in it proportional to today's need of users and in order to enhance its efficiency, provides the conditions to achieve some parts of a sustainable architecture.

The aim of this paper is to explore conventional methods of teaching the arch-design studio with ideas of sustainability and creativity as agents of change. If this is realised, it means the students of architecture can be grounded in designing with sustainability and creativity ideas and can be professionals that design and build with ideas of creativity and sustainability. So, there are real buildings and places that satisfy our clients, the society and in harmony with the environment. The objectives are to know those and what it takes to participate and to explain and recommend the methods in teaching the arch-design studio. Stakeholders of architectural education have observed that the architectural design studio teaching is failing to meet the yearnings and needs of the users, societies, cultures, environments and technological developments and for solution have strongly argued for sustainability and creativity as a combined force of teaching the arch-design studio. Although there are similarities in the curricula of training architects all over the world, but educators go about it in their own convenient and suitable ways and styles and the ideas of sustainability and creativity are not taken seriously and also not formally incorporated in the curricula of training. These stakeholders say that something has to be done to improve the ways and methods of training architects, especially the teaching of the arch-design studio. The study finds collaboration of the academics and practicing architects, integrated team work of inter/multi-disciplinary and selection criteria in teaching the methods of ideas relating to sustainability and creativity in the arch-design studio.

Urban space has been formed in historical texture of cities under the influence of meaning and shape on the one hand and qualities related to human behaviors on the other hand. Among these points, neighborhood centers as the most important areas of social life in urban open space play a critical role in attracting people and improving quality and vitality of environment. This study presents the related literature in an analytical approach and expresses the relationship between neighborhood centers and human presence by structure analysis; it focuses on rules governing presence quality and formed behaviors in this places. In this survey, human and his presence in neighborhood centers are evaluated and urban spaces concept is formed by composing space location characteristics and human behavior. At least, it is sated that people`spresence in urban space of neighborhood centers expresses their thoughts and cultural interactions whose form shows its function and meaning. Therefore, humans would appear in urban space in a way that neighborhood centers quality depends on activity kind and their user's behavioral patterns.
