    Developing a Model for User Satisfaction Assessment in Energy Efficient Dwellings
    (Univ Politecnica Catalunya, 2022) Usma, Gokhan; Akinci, Nazli Ferah
    Energy efficient dwellings are the buildings, energy consumption of which is minimized throughout their design, construction process and the whole life cycle. They are also defined as buildings which ensure healthy and productive environments for their users. However, the research on energy efficient dwellings in the literature, on the other hand, mainly addresses the topic in the context of environmental and economic sustainability. Residential user satisfaction, which is among the most important factors in the architectural design process, not sufficiently emphasized in the research on energy efficient dwellings. This study aims to determine the user satisfaction in energy efficient dwelling design and application studies comprehensively. Ultimately, it is aimed to develop a model of user satisfaction measurement which can be used throughout the design / construction process and afterwards to this end. Model components were derived from the analysis of various indicators. In this process, characteristics of energy efficient buildings, certification system criteria, housing quality standards and indicators obtained from the academic studies in the literature were taken into consideration. The assessment proposals formed in this way were applied to the pre-determined residential users, and then the indicators were reviewed. In the light of the data obtained through the field survey, the main themes and sub-indicators of the model were finalized. At the end of all the analyses, the explanatory power of the themes of the model were found satisfactory on the phenomenon that is aimed to measure.

    DEVELOPMENT AND ASSESSMENT OF A POST-OCCUPANCY EVALUATION SCALE FOR SUSTAINABLE OFFICE ENVIRONMENTS INSIGHTS FROM THE FNN SUSTAINABILITY CENTRE
    (Univ Zagreb Fac Architecture, 2024) Usma, Gokhan; Olcer, Deniz Erdogan
    This study explores the relationship between users and the built environment through a post -occupancy evaluation (POE) conducted at the FNN Sustainability Centre, a noteworthy sustainable building in the region. The study involved a comprehensive approach, encompassing site visits, managerial interviews, and staff surveys. To establish a robust evaluation framework, a scale was developed by analysing pertinent literature, and indicators were identified to gauge various aspects of the building's performance. Throughout the scale development process, the SPSS data analysis program was used, and expert opinions were solicited to ensure a rigorous and comprehensive methodology. Evaluation categories included lighting, acoustics, climatic comfort and indoor air quality, use and comfort of systems, quality of space and perception, awareness of sustainability and productivity. The building emerged as a physically and psychologically conducive workplace that heightened employee awareness of sustainability. Specific concerns were identified, such as noise disturbance for open -office workers and glare -related issues, which serve as valuable feedback for potential adjustments.

    The Influence of Hot and Humid Climate Data on Modern Architectural Façade Design: A Case Study of Educational Buildings in Adana, Türkiye
    (MDPI, 2025) Usma, Gokhan; Kok, Derya Sokmen
    This study focuses on how modern architecture can be interpreted using regional data and how hot and humid climate data ultimately affect fa & ccedil;ade design. Despite modernism's dominance in 20th-century architecture, research on its adaptation to climates remains limited. Five educational buildings of modern architectural style in Adana, T & uuml;rkiye, a city with a hot-humid climate, were selected for detailed analysis. These buildings were evaluated based on key fa & ccedil;ade parameters such as opening configurations and solar shading elements. Additionally, thermal imaging, sun-path diagram simulation, and thermal comfort evaluations were conducted to assess fa & ccedil;ade performance. The findings suggest that contrary to criticisms of modern architecture's disregard for local conditions, the studied buildings integrate climate-responsive design strategies. In contrast to contemporary architecture's reliance on technical equipment for thermal comfort, this study also demonstrates that passive design strategies and structural decisions can offer effective alternatives in hot and humid climates.

    User satisfaction in multi-storey energy-efficient housing: Implementation of an evaluation model
    (Croatian Association of Civil Engineers - HSGI, 2025) Usma, Gokhan
    User satisfaction with housing plays an important role in improving the quality of life of individuals and sustainable building designs. Measuring user satisfaction is a crucial tool for assessing the suitability of housing to meet user needs and expectations. In this context, assessing user satisfaction with energy-efficient housing is of great importance in terms of both saving energy and increasing comfort. The study aimed to evaluate user satisfaction with a multistorey energy-efficient housing project by using a user satisfaction model in energy-efficient dwellings. The application and testing of the model in a residential project constitutes the unique value of this study. The model was applied to the users of a multistorey housing project in Istanbul through a questionnaire survey. The effects of energy-efficient building elements and insulation, heating, and cooling systems on user satisfaction were evaluated. User satisfaction was evaluated through the themes of comfort conditions, dwelling-environment relationships, health, and system characteristics and service features. The comparison of all themes indicated that 'health' had the lowest satisfaction level owing to insufficient operable windows, limited natural ventilation, and humidity regulation issues, which likely contributed to upper respiratory tract complaints. This study provides important implications for the design of energy-efficient dwellings and for meeting user expectations.
