“…Sharing ECFs serves as an important mediator between energy efficiency, occupants' comfort and IEQ satisfaction. Regarding indoor ECFs, studies note that the interaction between occupants and control systems has direct impacts on energy consumption and individual comfort satisfaction [14][15][16].…”

This study investigates human-building interaction in office spaces across multiple countries including Brazil, Italy, Poland, Switzerland, the United States, and Taiwan. We analyze social-psychological, contextual, and demographic factors to explain crosscountry differences in adaptive thermal actions (i.e. cooling and heating behaviors) and conformity to the norms of sharing indoor environmental control features, an indicator of energy consumption. Specifically, personal adjustments such as putting on extra clothes are generally preferred over technological solutions such as adjusting thermostats in reaction to thermal discomfort. Social-psychological factors including attitudes, perceived behavioral control, injunctive norms, and perceived impact of indoor environmental quality on work productivity influence occupants' intention to conform to the norms of sharing environmental control features. Lastly, accessibility to environmental control features, office type, gender, and age are also important factors. These findings demonstrate the roles of social-psychological and certain contextual factors in occupants' interactions with building design as well as their behavior of sharing environmental control features, both of which 2 significantly influence building energy consumption, and thus, broader decarbonization.

“…This task level might be the surrounding or background level of another occupant, but because it is most determinant for the comfort of the occupant to whom it provides the task level, it should be set according to her or his preferences. The surrounding luminance can be personalized when other coworker(s) sit(s) at another desk group; the background luminance will always need to satisfy all present coworkers; consensus control can solve this issue (see, for example, Lashina et al 2019).…”

Dynamic lighting is one of the new trends in lighting research; providing the right lighting level at the right time could possibly increase the alertness and performance of office workers. However, they might have preferences that deviate from this "healthy" lighting. Simultaneously, the building environment becomes increasingly automated, with occupancy-based control as one of the most well-known examples to reduce offices' lighting energy consumption. Nevertheless, preferences for lighting levels in the unoccupied area of the multi-occupant office space have not been addressed yet. Therefore, we studied luminance distribution preferences in relation to time of day and subjective alertness (SA) in a single occupancy scenario. Participants (N = 30) set the surrounding and background lighting six times a day as we first probed for SA. Our results clearly showed that a subset preferred varying luminance distributions; participants had fluctuating feelings of alertness, too. Preferences deviated sometimes from the typical dynamic lighting scenarios, suggesting that they do not always prefer healthy lighting. Moreover, we identified an effect of SA on the preferences, both with and without controlling for time of day. Hence, this study showed that we need to address these two factors when we want to provide satisfactory lighting conditions in case the office is not fully occupied. These are likely to affect other lighting preferences and therefore deserve more attention from research. Because we identified large individual differences, we suggest personalizing dynamic scenarios as the focus of future research.

“…A more recent study (van de Werff et al, 2017) confirmed this finding, also postulating that lighting is adjusted only if it does not lead to conflicts in a shared environment. Although conflicts are usually avoided, Lashina et al (2019) found that some users would tend to change the lighting setting anyway (dominant behaviour), while other users would just accept the change, even if they are not satisfied with the new lighting conditions (submissive behaviour). However, some users do not react to changes because they have high tolerances to lighting variations (Despenic et al, 2017).…”

“…However, the number of interactions mainly varied between individuals rather than interface designs, but all interfaces received a gradually reducing number of interactions, suggesting a sort of behavioural "wow" factor that fades with time. To avoid this, one could deprive the user of the interface for then providing it again later; this would prompt a so-called "loss aversion" (Lashina et al, 2019). In a study of lighting in open plan offices, indeed, Lashina et al (2019) found that individuals appreciate and use the interface more frequently after the forced loss.…”

Measures for the reduction of electric energy loads for lighting have predominantly focussed on increasing the efficiency of lighting systems. This efficiency has now reached levels unthinkable a few decades ago. However, a focus on mere efficiency is physically limiting, and does not necessarily ensure that the anticipated energy savings actually materialise. This paper presents a literature survey aimed at identifying control strategies and user behaviours leading to a reduction in lighting energy use. Whenever possible, the strategies and behaviours discussed are supported by quantitative data. This survey is part of a more extensive review of the potential for reducing energy use through the integrated design of daylight and electric lighting and their control systems. It concludes with identifying key aspects for lighting control decisions with respect to daylight use, control strategies, control interfaces, feedback systems, rebound effects and social norms regarding user behaviour and makes recommendations for further research.
