“…The main challenges in the current elevator machine room planning-inefficient communication and predominant use of 2D drawings-have been encountered in other construction projects [1,2,19,24,50,52]. All benefits found in this study correspond to findings of many others that investigate single-user VR [18,52,54,66] and multi-user VR [3,19,20,67,68] in the AEC industry. Users recognize the strong sense of presence, the flexibility in viewing immersive and full-scale environments, as well as the ease of communication as the key benefits of VR.…”

Virtual Reality (VR) is considered among the major technologies to address the inefficient collaboration issue caused by the predominant use of 2D drawings in the construction industry. However, there is still a knowledge gap between researchers and practitioners about the actual benefits of VR in the business context. This paper presents the benefits of VR usage in four real-life high-rise elevator projects from the user and business perspectives. Four VR environments of actual machine rooms for planning were created and tested in a multi-user setting. Overall, users find VR more intuitive than conventional tools to enhance planning accuracy and collaboration. The results also show that VR brings significant economic savings and gains for business in the industry. Future study should investigate the real cost-benefit ratio of VR and streamline its technical implementation within construction projects. The research contributes to the current body of knowledge by providing real-life economic benefits and directions to address the research gap in both academia and industry to promote the wide adoption of VR.

“…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.…”

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.

“…Since the chromogenic windows have the features of dynamic changing of solar transmittance, which increase the difficulty of setting up and control the experiments. In the past decades, the combined use of advanced VR technology and building design have realized the test of user behaviour and achieve energysaving [13][14] . Shahinmoghadam et al integrated the Internet of Things (IoT) and VR in the development of immersive VR applications for real-time monitoring of thermal comfort conditions.…”

Chromogenic windows enable both energy-saving and daylighting regulation. However, the human response to the luminous environment affected by them is difficult to test, since their features of dynamic change and tinting automatically. This study explores the research methods, including experimental design and statistical analysis, by literature review and an experiment demonstration. The results show that a proper size of the test room is significant to obtain desired data, and the advanced VR technologies have the potential to be applied for testing these dynamic variables. Bayesian approaches are recommended to be tried and get more accurate interference about the experimental results.
