Exploring Effective Sensory Experience in the Environmental Design of Sustainable Cafes

The aim of this study was to explore and construct spatial indicators suitable for green cafe ambience. The indicators were further empirically verified. A three-round questionnaire survey, based on the Delphi method, was conducted with 15 experts, including university professors (food and beverage services management and interior environmental design), cafe operators, and personnel from government agencies. Data were collected, and the results on the characteristics of the repeated feedback from the experts were convergent. Thirty-six indicators suitable for the design of green cafe ambience were extracted, of which 17 were verified by actual cafes as highly operable. The five-sense indicators of sustainable green ambience design obtained in this study can facilitate positive customer experiences and enhance the appeal of maintaining sustainable green trends for cafes. These indicators can also provide references for cafe operators in business planning and green cafe ambience design.
