| Abstract |
As urbanization progresses, power and energy facilities play a crucial role in urban infrastructure, yet their visual impact is often underestimated. This study investigates the influence of biophilic design on public visual attention and subjective evaluation of facade designs for power and energy facilities. The research objectives are: (1) to examine how biophilic design enhances visual attractiveness and subjective evaluation of power and energy facility facades; (2) to compare the effectiveness of direct and indirect biophilic designs in capturing visual attention and improving subjective evaluation; and (3) to explore the relationship between key visual attention metrics, particularly fixation duration and fixation count, and the subjective evaluation of facade design. Combining eye-tracking technology with the Semantic Differential (SD) evaluation method, a quantitative analysis was conducted under three facade design conditions: traditional design, indirect biophilic design, and direct biophilic design. The results indicate that biophilic designs significantly enhance both visual attention and subjective ratings, with direct biophilic design being the most effective. Additionally, key eye-tracking metrics show a significant positive correlation with subjective evaluation of facade design. These findings provide valuable insights for integrating natural elements into the architectural design of urban infrastructure-particularly power and energy facilities-to enhance public visual experience and perception, contributing to improved urban spatial design. |
