“…Unfortunately, not all studies testing the hue‐heat hypothesis reported the light intensity that was used during the experiments . Also, the duration of exposure could play a role, as, in the aircraft studies, the effect was measured after only 10 min of light exposure . In the current study, the duration of the light exposure was 225 min (three times 75 min) and preparations were done under the same light conditions.…”

Expanding the acceptable range of indoor temperatures allows to reduce building energy consumption and may be beneficial for health. Therefore, we explored whether light conditions can be used to influence thermal perception under various ambient temperatures. In two laboratory experiments, we tested the effect of the correlated color temperature of light (2700 K and 5800 K) and its intensity (5 and 1200 lux) on thermal perception. The light exposures were provided during cool, neutral, and warm thermal conditions. Cold-induced perceived shivering was higher for the 5800 K light exposure. All other parameters related to thermal perception did not significantly differ between the light exposures. Interestingly, the other way around, an increasing ambient temperature resulted in a warmer perception of the light color. In every light condition, it appeared that the perceived light intensity was closest to neutral under the thermoneutral condition. Between different light sessions, the change in visual comfort and the change in thermal comfort were positively related. The main conclusion therefore is that thermal discomfort can be partly compensated by lighting that results in a higher perceived visual comfort. Field studies are required to demonstrate whether lighting can enable new strategies to improve indoor environmental workplace satisfaction.

“…However, in some cases not all the possible combinations of levels across factors have been tested, thus resulting in a fractional factorial design ( fractional ) . In other investigations, only one environmental factor was manipulated, while maintaining other factors at a constant level, to determine whether this had an effect on the subjective perception of other unchanged environmental factors ( one factor ) …”

This study reports the outcomes of a literature survey aimed at exploring how different environmental factors-that is acoustic, thermal, visual, and air quality stimuli-interact in affecting building occupants' perception and performance. Recent laboratory studies have been collected, and their methodological approaches reviewed in terms of experimental design, adopted exposures conditions, perception and performance assessment methods. Results have been summarized and compared to identify interaction patterns between environmental factors and possible practical implications for improving the design of both experimental studies and the built environment. The analysis allows highlighting limitations, potential improvements and future opportunities in this field of research, thus providing a reference for further investigations aimed at a deeper understanding, modeling, and prediction of the impacts caused by the main indoor variables on human comfort and performance.

“…Some studies discussed physical environment factors that affect passenger comfort, such as vibration (Šika, Valášek, Vampola, Füllekrug, & Klimmek, ), noise (Quehl, ), light (Winzen, Albers, & Marggraf‐Micheel, ), temperature and humidity (Giaconia, Orioli, & Di Gangi, ), and air quality (Winzen & Marggraf‐Micheel, ). Bubb () proposed a discomfort pyramid that prioritized the importance of different elements of the cabin environment.…”

With the increase in air travel, comfort is becoming an important issue with which airlines differentiate themselves in a competitive market. Passengers are paying more attention to their comfort experience during flights. However, passenger comfort is affected by various factors that result from the complex cabin system. Besides, the factors have interrelations between one another. How to identify the key factors and comb through their interrelations to improve passenger comfort efficiently is a critical problem in cabin design. To solve this problem, a hybrid model is proposed to identify the key factors and discuss the interrelation between them based on the questionnaire data. First, factor analysis is conducted to segment complex influencing factors into groups and to extract the most important factors. Decision Making Trial and Evaluation Laboratory (DEMATEL) method and fuzzy set theory are combined in the next analysis, considering both the interrelation between factors and the fuzziness of subjective comfort perception concurrently. It forms a structural model and then visualizes the causal relationships among factors through a causal diagram. The results of an empirical study show that the proposed model is capable of identifying the critical factors that affect passenger comfort effectively and could offer a priority of factors to improve passenger comfort.
