User satisfaction in multi-storey energy-efficient housing: Implementation of an evaluation model

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.
