# Exploring the Impact of Thermal Environment on Student Well-Being in Sustainable Campus Settings
## 2 Methodology  
### Overview of the Survey Site  
This study investigates the psychological perceptions of female students at the UAEU female campus, focusing on the impact of abaya colors, landscape types, and times of day. The procedure for administering the subjective survey followed the guidelines outlined in ISO 10551 [49], which provides standards for assessing thermal comfort based on subjective human perceptions. This framework emphasizes the importance of subjective surveys for evaluating personal experiences in relation to environmental factors. A quantitative approach was employed to assess eight psychological parameters: body fatigue, eye fatigue, body heat, skin dryness, thermal discomfort, desire to escape, site unattractiveness, and unproductivity (Appendix A.1). Participants rated these parameters on a 5-point Likert scale, where 1 indicates the lowest intensity and 5 indicates the highest intensity [48; 50; 51; 52; 53] (Appendix A.2). This method aligns with ISO 10551's emphasis on using clear and standardized scales to evaluate subjective comfort levels, ensuring that data can be effectively analyzed and compared across participants. Surface temperatures were monitored using FLIR thermal cameras to evaluate thermal conditions at different locations. Data collection occurred on 21-22 June 2023 (summer), and 23 March 2023 (spring), at the UAEU in Al Ain City, UAE. The emissivity during March and June was measured at 0.95, with a reflective temperature of 20 \({}^{\circ}\)C, a relative humidity of 50.0%, and measurements taken at a distance of 1.0 m. By employing this methodology, this study captures the psychological and thermal impact of environmental factors such as Abaya colors, landscape types, and times of day, offering valuable insights into how the environment influences both thermal and psychological comfort. Figure 1 illustrates the data collection site. This study utilized a convenience sampling approach, selecting six female students based on their availability and interest, with three participants per season. Each student experienced three landscape types--naturally shaded, artificially shaded, and unshaded--at specific times: morning (7:00 am-10:00 am), afternoon (1:30 pm-2:30 pm), and evening (8:00 pm-9:00 pm) (Table 1). Participants wore one of three abaya colors--black, white, or light brown--and spent 10-15 min at each site completing a questionnaire on their psychological perceptions of thermal comfort [48]. Thermal conditions were assessed with thermal cameras, and perceptions were evaluated through the Likert scale-based questionnaires. This setup enabled comparisons of how thermal exposures, shading, and clothing colors influence comfort and well-being, providing valuable insights for creating sustainable and comfortable campus environments. This study examines students' thermal perceptions in Al Ain City, UAE, during spring and summer. Four maps were created, showcasing average temperatures and relative humidity for March and June 2023 (Figures 2 and 3), derived from ECMWF ERA5 dataset via GrADS. These maps focus on crucial parameters: relative humidity and surface-level temperature. Additionally, the study investigates long-term temperature trends at UAE University from 1963 to 2023, using Microsoft Excel to graphically represent monthly average temperatures for March and June. The analysis anticipates a consistent upward trend in temperature values over the years.
