Abstract: Previous laboratory experiments have provided evidence of an effect of time of day on glare sensation. During the tests, temporal variables and personal factors were also measured to analyse their influence on levels of visual discomfort as the day progresses. The results revealed statistically significant and practically relevant tendencies towards greater tolerance to source luminance from artificial lighting at all times of day for earlier chronotypes and for participants not having ingested caffeine. No conclusive evidence was found for the effect of fatigue, sky condition and prior light exposure on glare sensation throughout the day. These findings suggest that temporal variables and personal factors should be measured in conjunction with visual discomfort levels to explore the causes of the wide in idual differences commonly associated with the subjective evaluation of glare sensation.

Abstract: With people spending up to 90% of their time in indoor spaces, windows and the visual connection that they afford to the outside, can play an important role in ensuring physical and psychological well-being. This is particularly relevant in urban settings, a substantial part of our lives, whilst still being significantly understudied. What we know from other environments may not translate to cities, and there may be important differences between the expressed preferences of in iduals and their behaviour. Therefore, this study sought to define suitable methods and metrics to measure view preference in urban environments. Participants were asked to observe urban views whilst three types of data were collected: subjective preference ratings eye-tracking measures and verbal reasoning. We found that when views were preferred, the gaze of the observers was more exploratory, with a higher occurrence of fixations and number of saccades. In addition, participants tend to prefer the presence of people, well-maintained buildings and orderly presented colours. A new link was revealed between the degree of visual exploration and the preference rating of a visual scene. This characteristic pattern of oculomotor behaviour may guide the criteria for framing selected views and accordingly inform window design in buildings.

Abstract: Luminance adjustment is a procedure commonly used to evaluate discomfort glare and the results from adjustment experiments form the basis of some recommendations for limiting its occurrence. There are, however, strong reasons to expect that settings made using adjustment are unintentionally influenced by extraneous variables. This paper discusses bias towards the initial anchor, the setting of the variable stimulus immediately before an adjustment is made. Specifically, the initial luminance is expected to influence the setting that is made by adjustment for ex le, a lower initial luminance leads to a lower setting than a high initial luminance. To investigate anchor bias, a Hopkinson-like multiple-criterion adjustment experiment was undertaken, but with three different anchors. The results confirmed significant bias: glare settings were biased towards the luminance of the initial anchor. This demonstrates a need for caution when using adjustment to explore discomfort glare and when interpreting the results of past studies that used discomfort glare models fitted to data obtained with this procedure.

Abstract: There are strong reasons to suspect that glare sensation varies with the time of day. This study was designed to test whether such a relationship exists. Thirty subjects were exposed to an artificial light source four times of the day. The source luminance was progressively increased and subjects were required to give glare sensation votes corresponding to the level of visual discomfort experienced. Glare indices were calculated for every reported glare sensation vote, and the results were statistically analysed. The findings indicated a tendency towards greater tolerance to luminance increases in artificial lighting as the day progresses. This trend was found not to be statistically related to the possible confounding variable of learning, providing evidence of an effect of time of day on glare sensation.

Abstract: This study aims to explore the opportunities offered by interactive and situated learning (e-learning and m-learning) in support of education for sustainability in disciplines of the built environment. The paper illustrates the development of an online portal and a mobile app aimed at promoting students’ motivation and engagement with sustainability in design, and discusses the outcomes of their testing, investigating users’ acceptance, comparing academic results and analysing feedback. The findings add empirical evidence to the view that information and communication technology-enhanced pedagogies can substantially contribute to the agenda of sustainability in higher education, primarily due to their affordance of interactive communication and contextualisation of knowledge, while guaranteeing flexible time and pace of learning. The study solely focused on the development and testing of e-learning and m-learning tools to foster students’ competence of sustainability in design studio work. The tools trialled were mostly at their prototypical stage and their testing included a relatively short-term evaluation and a narrow, self-selected, user base. However, the approach and findings are felt to be applicable to a much wider range of educational contexts. Interactive and situated pedagogical methods and tools have the potential to prompt a departure from transmissive educational models, encompassing at once theoretical, experiential and analytic learning processes. This is of value to education for sustainability in disciplines of the built environment due to the requirement to holistically consolidate multi-/inter-/trans-disciplinary knowledge into a coherent design whole.
