The Origin and Nature of Productive Theory, Based on Design Theory, with a Focus on Design in the Field of Architecture

Design theory as the epistemological and knowledgeable core of the design process is the basis for its identity. Along with the emergence of engineering design, developments in design theory have had an increasing impact in many disciplines and academic societies. In a way, design theory has been effective in several academic fields such as creative research. In the field of architecture, the importance and position of theoretical foundations in architecture has long been such that the evaluation of the design product, to a large extent (especially in its current manifestation in the present post-postmodernist era), is supported by the theoretical foundations reflected in form and body. However, due to the lack of a general framework for presenting these solutions, there are frequent discussions about logic, theoretical foundations and even the values of contemporary design. So, it can be said that the present design theory should cover all the steps that are considered in the field of theory to the product of architecture. Consequently, the theoretical foundations of architecture as the most important area of identity to architecture, as a field of study, aimed at defining design or, more precisely, design. In such circumstances, addressing every design problem requires a variety of data and information that is collected and analyzed in a specific way, in line with the objectives defined in a systematic model. In the field of design recognition with such new specifications and approach, design theory can be viewed in a new way. For example, the combination of systemic thinking with the theory (theoretical foundations) of sustainable architecture can be considered as a framework-creating solution. In this way, a new concept of this synergy, called the framework of «sustainable architectural identity», will be created The problem of defining and using theoretical foundations in scientific manner, along with other empirical, technical and skillful resources such as elite opinions and social memory, has created a necessity among designers. This necessity includes the formation of a discourse about what is and how to take a comprehensive, purposeful and systematic model of it. The purpose of this study is to provide a systematic definition of the nature of theoretical foundations in architecture, at three levels: promotion, adaptation and production of science. This perspective has been used to shape the mental structure of designers in relation to its nature, in a process-oriented and productive perception. Obviously, the application of such a thing can be expressed in the model-based use of theoretical foundations of architecture, especially in the process of parametric and algorithmic design, in the post-postmodernist era. The present qualitative research with the method of analysis and descriptive interpretations of library resources, while describing the shaping facts to the theoretical foundations of current architecture, tries to provide a systematic understanding of these factors. The important achievement of this research is achieving theoretical productive fields in architectural design, and shaping the logical model for encountering and intelligently utilizing architectural theory factors for proposed use in the framework of sustainable architectural identity.
