(in German)

The interactions between climate, noise and lighting in rooms of workplaces with regard to their influence on perception, comfort/well-being and cognitive performance of employees were researched within the framework of a literature study. 19 primary and 4 secondary studies were included. Most of them dealt with climate and noise in the context of office work with regard to comfort and well-being, some with cognitive performance, which was evaluated as a priority. References to lighting and related effects were not very pronounced and were not pursued in depth. The significance was limited by the more youthful test person population and relatively short test durations compared to real daily working hours. Women and men were mostly included in equal numbers (n from 20 to 130). In the primary studies, more or less significant effects could be determined above all in the interactions between climate and noise with regard to sensation (e. g. thermal, acoustic) and well-being (comfort, cosiness), less pronounced also with regard to cognitive performance. Overall, the influence of acoustic factors on indoor comfort is greatest, followed by room temperature and illuminance. There are indications of interactions between noise and temperature in the subjective perception and evaluation of comfort, e. g. thermal comfort decreases with increasing noise levels. As a result of the evaluation of the secondary studies, however, it can be stated that so far no significant interaction effects between the different working environment factors have been found and that further studies are necessary for this. In addition, model approaches for interaction (e. g. regression equations for acceptable ranges of temperature, illuminance and sound pressure level), for target values for optimal environmental conditions (t_a = +21 to +22 °C, E > 300 lx to 1000 lx daylight, line of sight to the outside, L< 50 dB(A)), with regard to gender-specific effects (e. g. light intensity), and with regard to the effects of the different working environments were developed. Gender-specific effects (women accept noisier environments, perceive lower temperatures as colder than men and higher temperatures as more pleasant) and the approach of "perceived control" (individually controlled working environment factors can lead to a high level of acceptance and comfort).
