Advances in technology have changed the lifestyles of most people around the world, thus causing an increase in energy consumption and environmental pollution. Since buildings’ facade can play an important role in providing human comfort, decreasing energy consumption, and environmental pollution, facade design should integrate various technologies together by considering construction materials, cost-effectiveness, occupant’s requirements, and climatic zones. Considering all of these design parameters together and their complex relationships with each other is not easily achieved by applying conventional design methods. Hence, the Quality Function Deployment (QFD) method, which is based on considering users’ needs throughout the design and production phase of industrial products, was studied and the possibility to adapt it to design appropriate building facades was explored. In this dissertation, a framework, which consists of four phases, was defined by adapting the QFD method. These phases are; Design targets phase, Occupants’ requirements phase, Design techniques phase, and Facade design phase. These phases consist of various steps including analysis of 49 case studies, two questionnaire surveys, five Analytic Hierarchy Process (AHP) matrices, and two House of Quality (HoQ) matrices. To complete these phases, the primary and secondary design targets were determined from a comprehensive literature review and analysis of 49 case studies. Then, this information was used to prepare questions for two dedicated questionnaire surveys regarding the design targets, occupants’ requirements, and technical solutions. The surveys were fulfilled by identifying the preferences of occupants regarding their requirements and design targets in the first survey, and preferences of architects about technical solutions and design targets in the second survey. These surveys were conducted with 120 occupants (66 from Turkey & 54 from Iran) and 82 architects (40 from Turkey & 42 from Iran). The data from the questionnaire surveys regarding the primary and secondary design targets were used in five AHP matrices to calculate their priorities. The data from the questionnaire surveys regarding the occupants’ requirements and technical solutions were used in the first HoQ matrix to determine the priorities of the technical solutions. In order to calculate the priorities of the appropriate facade systems, output of the first HoQ matrix was transferred to the second HoQ matrix to find their correlation with facade systems determined from the case study buildings. According to the results of the QFD matrices, it is found that adapting QFD method for architectural design improves the design process. Consequently, the occupants’ requirements and architects’ opinions regarding the complex design parameters were transferred from one design phase to the other without getting lost to achieve a universally acceptable and appropriate facade design. In conclusion, the QFD framework proposed in this dissertation can be used not only to design appropriate facade systems but also other building components, even entire buildings, by considering user requirements.

Investigating the performances of photovoltaic modules/systems for Central Anatolia using a thermal modeling approach Tunçel, Bilge; Akınoğlu, Bülent Gültekin; Department of Physics (2019) Effective use and performance enhancement of the renewable energy systems are becoming increasingly important as climate change is widely recognized as one of the most crucial problems for the Earth. Turkey, a country within the solar belt, has an abundance of solar energy potential. Economical, environmental and physical investigations are needed to ensure effective utilization of this potential. In this thesis, using the meteorological parameters of the Central Anatolia and parameters of photovoltaic (PV)...
Adopting sustainability assessment criteria to guide urban regeneraton projects: two case studies in Ankara Seyhan, Zeynep.; Elias Özkan, Soofia Tahira; Department of Architecture (2019) Increasing awareness of climate change, loss of biodiversity and increase in environmental pollution due to the current trends of consumption in the urban areas have brought about a myriad of schemas to guide environmentally friendly urban developments. These schemes or Neighborhood Sustainability Assessment Tools (NSA Tools) provide a convenient way to establish healthier and sustainable cities. Meanwhile, Turkey is going through a rapid urban transformation process that is being questioned with respect to...
A Facade mapping method to understand human comfort in buildings with highly glazed facades Tüzer, Ceren.; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2019) The energy demand of societies increases continuously with related to technological improvements, population increases and daily needs. Building sector is one of the highest energy consumer sector. Office buildings are also critical type of buildings, because these types of buildings generally accommodate lots of occupant and there is high demand of energy for lighting, heating, ventilation, and air conditioning to provide indoor air quality, thermal and visual comfort. The buildings with glass curtain wall...
A multiobjective approach to energy environment planning problem Arikan, Y; Kilic, C (1996-05-16) The energy planning problem has gained a new dimension in view of the effects of energy production and consumption on environmental decline and ecological damage. The problem was usually formulated in total cost minimization form and the environmental effects of energy activities were not taken into account. It has been well understood now that decisions concerning energy supply cannot be based on a single objective, since energy policies have multiple consequences which cannot and should not be ignored. Th...
A data-driven approach for predicting solar energy potential of buildings in urban fabric Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7) Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
