This paper aimed to develop a multisensory approach in a university campus, based on quantitative and qualitative approaches, investigating sense walk experiences (thermo-visual sound walk) under interactions of luminous, thermal, and auditory environments. The study was conducted in October 2021, in Chetma university campus in Biskra city, southern Algeria, which remains a famous oasis settlement of arid regions over the country. A comparative and correlation analysis was performed between the physical dimensions collected through a walking experience in three campus routes (outdoor, semi-outdoor and indoor). In addition, a multisensory survey of the walking experience on perceptual dimensions was evaluated in parallel to the empirical contribution. The paper shows that walkers’ thermal levels were balanced between neural and slightly hot in different spatial aspects. The glare was almost unperceived regarding the luminous conditions in the study site. The auditory experience reveals that the conducted points were generally quiet and well placed for educational requirements. Findings also show a strong relationship between the physical dimensions of the luminous and auditory environment. Furthermore, the findings suggest that the thermal and luminous environments are more perceptible than the auditory environment for the walkers of the outdoor and indoor routes. In contrast, the semi-outdoor route is often perceptible by the perceptual dimensions of the luminous and auditory environments. The findings on sensorial thresholds and spatial adaption are essential for the educational practices’ architectural and urban strategies for the Saharan cities and oasis settlements.

The feeling of calm and tranquillity provided by the oases of Algeria can disappear because of the outdated urbanization strategy which is based on the vehicle as a mode of transport. Walkability is one of the most adoptable sustainable strategies to reduce the negative mechanical transportation effects on the quality of life. This paper aimed to examine the correlation and the causation between oases soundscape components and walking speed. The methodology of this field study was based on an empirical approach at the urban settlements in three oases in Algeria. The correlation between walking speed and soundscape components was obtained through the use of the Spearman correlation test. A one-way ANOVA analysis was conducted to assess the effect of the soundscape components on walking speed. A post hoc Tukey test was adopted to explore the sound component that causes increased walking speed. In this study, no significant correlation was explored between the walking speed and the anthrophonical sounds. In contrast, the statistical analysis of the sound walks experience suggests a moderate and significant negative correlation between geophonical and biophonical sounds, with mean walking speed. The results showed that, the cause of the increase in the mean walking speed of the pedestrians is human sound. The findings suggest that further research is needed to focus on the long-term subjective investigation to explore the correlations and the effects between soundscape, walkability and walking speed.

Inclusive design (ID) is a design process that ensures that all people, particularly marginalized groups, can use the environment. Inclusive design (ID) in architecture is based on accurate data related to user experiences where the users’ perception of the built environment demonstrates the optimal facilitation of their expectations, needs, and demands. Despite this, in studies about inclusive design and multisensory architecture, the perspective of visually impaired people (VIP) is still lacking, especially in accessing public spaces. To address this gap, this study aims to investigate how sighted and visually impaired people perceive an oasis settlement urban park’s physical environment and verify the similarities and differences between these two categories. The research was conducted by applying two approaches, one qualitative based on a series of field surveys and the other quantitative relying on in situ measurements of the physical dimensions of the environment. The main findings of this study show that visually impaired people deserve special consideration due to their varying abilities to perceive the surrounding environment. Furthermore, the results indicate that auditory environments are more perceptible to the visually impaired than the sighted. In contrast, findings from the analysis of the perceived restorativeness scale (PRS-11) show that sighted users of the park have a slightly higher average score than visually impaired users regarding its components of Fascination, Being-Away, Coherence, and Scope. According to the Semantic Differential Scale of Multi-Variable Evaluation of the Park Environment, there are no significant differences between park users’ perceptions of the park’s nature and the thermal environment. The conclusion suggests that to ensure users’ well-being, it is crucial to understand the different individual needs among groups of users and come up with innovative and all-inclusive solutions.

The urban heat island (UHI) significantly compromises outdoor thermal comfort and public health in hot climates. While urban vegetation is a recognized mitigation strategy, its performance variability across different urban fabrics remains a critical knowledge gap. This research quantitatively evaluates the microclimatic impact of vegetation strategies by comparing two districts with distinct urban morphologies: low-density and high-density. Using the Envi-met software, we simulated a reference case and four vegetation scenarios with constant 50% grass coverage and incrementally increasing tree percentages (0% to 75%). Thermal performance was assessed through key metrics, including air temperature (Ta), relative humidity (RH), mean radiant temperature (Tmrt), and Physiologically Equivalent Temperature (PET). The results reveal that vegetation’s effectiveness is directly correlated with urban density. The most comprehensive strategy (Scenario-D: 50% grass, 75% trees) reduced peak PET by up to 7.5 °C in the low-density El Khazzan, a reduction nearly three times greater than the 2.7 °C achieved in the high-density El Akkad. Similarly, this scenario achieved a maximum daytime Ta reduction of 0.92 K in El Khazzan, compared to only 0.4 K in the high-density district. The study also identifies a critical trade-off: high-density tree scenarios increased nighttime temperatures by up to 0.4 K due to disrupted airflow, whereas the grass-only scenario maintained thermal stability. These findings underscore that a one-size-fits-all approach to urban greening is insufficient. For practical implications, urban planners must abandon generic strategies and integrate a nuanced understanding of local morphology to maximize the thermal benefits of vegetation, particularly in hot, arid environments.

The user’s experience is critical in spatial design, particularly in outdoor spaces like university campuses, where the physical environment significantly influences students’ relaxation and stress relief. This study investigates the combined impact of thermal, luminous, and auditory environments on students’ perceptions within recreational areas at Bordj Bou Arreridj University Campus. A mixed-method approach combined field surveys and on-site measurements across eleven locations within three distinct spatial configurations. The findings from this study indicate that the auditory environment had the most substantial influence on overall perceptions, surpassing luminous and thermal factors. The open courtyard (Area 1) was perceived as less comfortable due to excessive heat and noise exposure. The shaded zone (Area 2) was identified as the most vulnerable, experiencing significant thermal stress and noise disturbances. In contrast, the secluded patio (Area 3) achieved the highest comfort rating and was perceived as the most cheerful and suitable space. Correlation analysis revealed significant interrelationships between physical and perceptual dimensions, highlighting the critical role of factors such as wind velocity, sky view factor, and illuminance in shaping thermal, luminous, and acoustic perceptions. A fuzzy logic model was developed to predict user perceptions of comfort, suitability, and mood based on measured environmental parameters to address the complexity of multisensory interactions. This study highlights the importance of integrating multisensory evaluations into spatial design to optimize the quality of outdoor environments.

A quantitative evaluation of noise pollution in the public gardens of Biskra, Algeria, was carried out in this research. The equivalent sound level (leq1min) was measured in 27 points distributed over the seven main gardens of the city. The results of the measurements show that the measured level of sound intensity varies from 56.38 dB in the Landon garden to 62.55 dB in the Larbi Ben Mhidi garden. By comparing, the measured values with the noise limit values recommended by the national legislation, the standards of the World Health Organization and the United States Environmental Protection Agency; it is clear that the sound environment in these public gardens do not comply with the recognized standards of acoustic comfort. The gardens’ spaces are heavily over-exposed to traffic noise resulting in high levels acoustic pollution.
