Veranda as one of the main elements of spatial hierarchy in the traditional Iranian architecture is responsible for providing visual and thermal comfort and energy saving, in the interior and to some extent exterior besides enhancing both the privacy and accessibility as a transition space all around the building. In the Solar Decathlon China 2013 (SDC 2013) house of Team Iran, the roof of veranda has been designed to be a functional part of the above goals. It is composed of several reflector pieces gathered in each veranda frame forming a traditional Iranian pattern. In the southern veranda roof, the reflector pieces are able to rotate on a daily basis, based on the amount of interior light intensity and optimal function of the water wall located in the southern facade. Through the current article this particular veranda design and its detailed mechanisms are thoroughly discussed. Lighting simulations have been performed for the interior of the house, with and without the veranda, in addition to covering different states through the day during distinct seasonal conditions for five specified geometrical layouts in the former case. Meanwhile, a data reduction procedure has been applied and validated by the obtained data in order to get an overall numerical interpretation of each case. The results confirm that the original width between the pattern elements in the traditional layout forms the optimum configuration and the rotation mechanism in the southern veranda roof further enhances the interior visual comfort.

Understanding façade between design and manufacturing : a case study on high-rise office buildings in İstanbul
Şener, Duygu; Güzer, Celal Abdi; Department of Architecture (2006)
The thesis aims to examine how the formation of façades, that is, the interface with a dual response both to interior functioning and exterior urban fabric, is separated from the totality of architectural design by new technological developments and design intentions. This aim is accomplished in three sections, respectively: “analysis of the façade, the properties and formation process in time”; “examining the façade formation of the high-rise office buildings in Levent-Maslak area in respect to the analysi...
The development of a building energy performance evaluation program (EnAd) for architectural design process
Çakıcı, Fatma Zehra; Sorguç, Arzu; Department of Building Science in Architecture (2013)
Energy performance in buildings has become one of the most broadly debated subjects in contemporary architecture; and current legislation has emphasized its importance by requiring buildings to possess an energy performance certificate. Due to the technological advances in computational tools, it is possible to analyze the energy performance of buildings before construction starts; however most energy performance evaluation tools, requiring complex solid models and high technical knowledge in the field, can...
An investigation into building occupant behavior of different household typologies in architecture
Erol Ağırsoy, Meliha İpek; Gürsel Dino, İpek; Department of Architecture (2022-2)
Humans who directly interact with the built environment are a significant parameter of the architectural design process. The uncertainty in occupant behavior is a variable parameter of sustainability in architecture. Human building interaction affects energy consumption and creates an unpredicted result for the building's calculated energy use. The interaction between the occupant and the building is significant for establishing new areas of architectural inquiry. The study aims to observe the influence of ...
Performative design processes in architectural practices in Turkey: architects’ perception
Ataman, Cem; Gürsel Dino, İpek (2021-10-01)
During the last decades, the increasing need to ensure building performance during architectural design has led to highly interactive relations between architecture and various other disciplines, in which concepts of sustainability and building performance are tightly integrated into the design process. However, the adoption of these concepts in architectural practices and the recent advancements in the field have remained rather slow. This research aims to understand performative design (PD) in the context...
Optimizing the fenestration of typical Turkish school building with respect to daylight and thermal performance
Dilber Kılıçarslan, Damla; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2013)
The aim of this study is the maximization of the occupant comfort with the minimization of the energy consumption for artificial lighting, heating and cooling in typical Turkish school buildings through the better design of the fenestrations which were predetermined with a directive called “Eğitim Yapıları Mimari Proje Hazırlanması Genel İlkeleri” i.e. the “General Principles For Preparing Architectural Projects For Educational Buildings” as a monotype regardless of orientation and climate. The study was co...
