“…The design team also explored the dynamic visual implications of urban infill projects and developed formal massing schemes that could induce satisfactory dynamic visual experiences. The simulation program's massing functionality can between those who evaluated design (students as designers) and those who were the end users of the designed environment (Watertown residents), a situation that Pre-Occupancy Evaluation using simulative methods should avoid (Shin et al 2017). Therefore, the analysis of simulated data did not create, move, and resize cubic volumes in different building materials.…”

This paper proposes a computer-aided Dynamic Visual Research and Design Protocol for environmental designers to analyze humans’ dynamic visual experiences in the city and to simulate dynamic vision in the design process. The Protocol recommends using action cameras to collect massive dynamic visual data from participants’ first-person perspectives. It prescribes a computer-aided visual analysis approach to produce cinematic charts and storyboards, which further afford qualitative interpretations for aesthetic assessment and discussion. Employing real-time 3D simulation technologies, the Protocol enables the simulation of people’s dynamic vision in designed urban environments to support evaluation in design. Detailed contents and merits of the Protocol were demonstrated by its application in the Urbanscape Studio, a community participatory design course based at Watertown, South Dakota.

“…Moreover, the quantitative performance of environmental systems is rarely compared to occupant experience of these systems, e.g., measured air quality and experienced air quality (For two recent exceptions, see Chang and Touchie (2017) and Touchie et al (2016)). However, there is growing interest in these, with some published studies [24][25][26][27][28][29]. Researchers have acknowledged the need for pre-occupancy evaluations in health care environments, for example, as there is an increasing focus on evidence-based design and a desire for more scientific bases for design decisions [30].…”

Rethinking Performance Gaps: A Regenerative Sustainability Approach to Built Environment Performance Assessment

Globally, there are significant challenges to meeting built environment performance targets. The gaps found between the predicted performance of new or retrofit buildings and their actual performance impede an understanding of how to achieve these targets. This paper points to the importance of reliable and informative building performance assessments. We argue that if we are to make progress in achieving our climate goals, we need to reframe built environment performance with a shift to net positive goals, while recognising the equal importance of human and environmental outcomes. This paper presents a simple conceptual framework for built environment performance assessment and identifies three performance gaps: (i) Prediction Gap (e.g., modelled and measured energy, water consumption); (ii) Expectations Gap (e.g., occupant expectations in pre- and post-occupancy evaluations); and, (iii) Outcomes Gap (e.g., thermal comfort measurements and survey results). We question which of measured or experienced performance is the ‘true’ performance of the built environment. We further identify a “Prediction Paradox”, indicating that it may not be possible to achieve more accurate predictions of building performance at the early design stage. Instead, we propose that Performance Gaps be seen as creative resources, used to improve the resilience of design strategies through continuous monitoring.

“…During the last decades, virtual reality (VR) is becoming increasingly common for the study of spatial behavior and cognition, as well as for other types of research, such as pre-occupancy building evaluations (Shin et al 2017) or evacuation and safety (Kinateder et al 2014(Kinateder et al , 2018. In order to reduce the frequently occurring issue of VR-induced motion-sickness, different approaches are used to emulate movement in VR, which include, among others: continuous translation, intermittent translation, teleportation, or the use of omnidirectional treadmills to provide proprioceptive feedback.…”

Immersive virtual reality (VR) technology has become a popular method for fundamental and applied spatial cognition research. One challenge researchers face is emulating walking in a large-scale virtual space although the user is in fact in a small physical space. To address this, a variety of movement interfaces in VR have been proposed, from traditional joysticks to teleportation and omnidirectional treadmills. These movement methods tap into different mental processes of spatial learning during navigation, but their impacts on distance perception remain unclear. In this paper, we investigated the role of visual display, proprioception, and optic flow on distance perception in a large-scale building by manipulating four different movement methods. Eighty participants either walked in a real building, or moved through its virtual replica using one of three movement methods: VR-treadmill, VR-touchpad, and VR-teleportation. Results revealed that, first, visual display played a major role in both perceived and traversed distance estimates but did not impact environmental distance estimates. Second, proprioception and optic flow did not impact the overall accuracy of distance perception, but having only an intermittent optic flow (in the VR-teleportation movement method) impaired the precision of traversed distance estimates. In conclusion, movement method plays a significant role in distance perception but does not impact the configurational knowledge learned in a large-scale real and virtual building, and the VR-touchpad movement method provides an effective interface for navigation in VR.
