A Case Study on the Odor Preferences and Influencing Factors in Chinese Residential Environments

Research on odor preference is needed to improve indoor environment quality. There-fore, to create a better odor environment in the living space, it is necessary to determine the common characteristics of odor preferences in the living environment for individuals with a similar cultural background. In this study, representative odors that are found in Chinese living spaces were selected and the odor preferences and individual traits were examined using online surveys. A total of 1236 valid responses were collected and the factors affecting odor preferences were assessed, including social, geographic, and behavioral attributes, using correlation and descriptive analysis. The results revealed that gender, age, occupation, income, mode, and frequency were correlated with odor preference characteristics in the living environment and were the primary factors for the odor preference characteristics. Further analysis revealed that the odor preferences across the gender, age, income, and frequency groups were consistent with the trend for the overall characteristics. The results of the study showed that there were significant differences in odor preferences in the living environment across occupations and living patterns. Different occupational groups showed different characteristics in odor preferences, while the complexity of living patterns and the frequency of odor exposure also had a significant impact on odor preferences. These research findings will enable us to develop customized fragrance solutions based on specific olfactory preferences related to gender, age, occupation, income level, and lifestyle. Integrating the study conclusions into the spatial layout, selection of decorative materials, and ventilation design of residential spaces has practical significance for creating living environments that better meet the needs of residents.
