Large scale projects have given way to individual, private initiative resulting in smaller interventions rarely exceeding one lot. For this reason architectural concepts, building types, scopes and construction technology have been marginalized and fallen under the influence of market mechanisms and stringent local planning procedures.New regulations on energy efficiency have risen the standards for thermal insulation therefore increasing the thickness of building enclosure. This actually means that construction costs are increased and net built area, therefore expected profit, reduced. In order to provide the viable ground for both implementation of new regulations and economic benefits for investors, authors of energy efficiency regulations in Serbia have noted a whole set of solar systems, among which

Architecture reflects on itself since Vitruvius, but it is difficult to define its epistemological base, so interpretations are sometimes developed in other disciplines. Thinking about architecture is about reflection on and extension of architectural concepts, cultural practices, and interrelated areas of art, philosophy, politics, etc. Incompleteness of understanding is obvious, and it points us toward a paradigm of complex thinking. Contemporary theoretical field of architecture is largely a product of postmodern architectural thought. This paper examines the position from which to build a modern architectural phenomenological opinion through three methodological models-creative, emotional and rational. This research should contribute to the way of understanding contemporary architectural phenomenon, with the intention of providing a general level of credibility and understanding in order to open the possibility of methodological application for a specific job or field.
