“…Also other findings of parameters' influence on participants' evaluations confirm the calidity of the model, according to the similarity of the results to the previous studies (e.g., window size effects on participants' spatial perception and satisfaction with amount of view as in [47] and higher occupants' satisfaction of visual comfort, inner space and openness with higher WWRs as in [39]). However in other studies [48], participants' perception and emotional states for instance satisfaction with view and amount of view is influenced by facade clarity and in [58] façade geometry has significant effects on perceived brightness and amount of view.…”

“…Also, the effect of furniture on brightness satisfaction was not statistically significant, but colored materials had a significant effect on participants' satisfaction with brightness [46]. While based on Chamilothori et al (2022) among different parameters (i.e., façade geometry, sky type, spatial context and country), the participants' subjective impressions is only affected by façade geometry [58].…”

Daylight improves indoor environmental quality, the physical and mental health of occupants, and their efficiency. Research in the area of human-centric lighting that considers the visual and non-visual effects of light on human vision, have focused on examining human visual perception in response to a wide variety of lighting aspects. To investigate the effect of surface materials, window size, and shading patterns on participants’ evaluation of brightness, daylight distribution, contrast, and satisfaction with view, a virtual reality experiment is implemented in a university classroom. Moreover, responses are compared with metrics (i.e., RAMMG and illumines level) to evaluate their performance and robustness. Thirty-three subjects evaluated thirteen immersive virtual environments (IVEs) with different glazing visible light transmittance, reflectance coefficient of surfaces, window to wall ratio, number of windows, and shading geometry using a Likert-type scale survey. The results indicated that participants’ evaluation of brightness is influenced by reflection coefficient of the surfaces and WWR. While daylight distribution is affected by number of windows and shading geometry in addition to other studied parameters. Based on the subjects’ responses the contrast is only affected by reflection coefficient of the surfaces. Their satisfaction with amount of outside view is also influenced by WWR and number of windows. Moreover, based on statistical results defining a specific range of acceptable contrast based on the RAMMG metric is not suggested, and users' evaluation depends on the surface material in addition to the reflection coefficient of them. Furthermore, the level of lighting perceived by people is affected by materials and their color (beside the reflection coefficient of the surfaces), number of windows (even with similar WWR), and shading pattern (even with the same aperture ratio) as well as the glazing visible light transmittance.

“…For example, Schielke 32 concluded similar subjective lighting impressions amongst participants from Europe, America, Middle East and Asia by comparing subjective responses to the online survey from small sample sizes (19-26 participants from each region). Moscoso 33 reported significant differences caused by socio-environmental contexts in terms of subjective evaluations of window sizes, whereas Chamilothori 34 found no significant differences caused by socio-environmental contexts in terms of subjective impressions of façade and daylighting patterns. Although these studies focused on lighting impressions by using different research methods (online survey or laboratory experiments), the influence of socio-environmental contexts on subjective lighting assessments is inconclusive.…”

“…However, the perceptual impressions of façade and daylighting patterns were similar amongst Norway, Switzerland and Greece. 34 Pierson et al 22 pointed out that no evidence suggested an influence of socio-environmental context on discomfort from daylight glare across Chile, Belgium, Japan and Switzerland. Different research methods and sample sizes of these studies might contribute to the inconsistent conclusions of socio-environmental contexts.…”

This study compares subjective evaluations of daylighting environments from two universities: the Singapore University of Technology and Design (SUTD) in Singapore and Southeast University (SEU) in Nanjing, China. Two hundred and twenty-nine students evaluated their instantaneous daylighting environments. Four representative daylighting predictors, horizontal illuminance, vertical illuminance, mean luminance of an entire scene and CIE Glare Index (CGI), were matched between two universities using a propensity score matching method. Eighty-eight participants, 44 from each university, were matched in terms of these four daylighting predictors. The results demonstrate that there are statistically significant differences in subjective assessments between these two locations. Under quantitatively similar daylighting environments, more participants at STUD reported adequate daylighting levels with a noticeable degree of daylight glare, as well as desires to decrease current daylighting levels. On the other hand, more participants at SEU reported inadequate daylighting levels with an imperceptible degree of daylight glare, as well as desires to increase current daylighting levels. One reason for subjective assessment differences might be dissimilar socio-environmental contexts, where the participants are acclimatized to different daylighting environments between Singapore and Nanjing.
