Due to necessity, people spend most of their lives in enclosed spaces. This creates the need to shape the indoor environment so as to form a state of satisfaction with their surrounding conditions. When shaping or assessing the quality of the indoor environment in buildings, we should primarily focus on its impact on the quality of life of users. Study and work environments are particularly important because attention needs to be paid to, among others, the significant relationship between the inappropriate quality of this environment and psychomotor skills, academic results, work efficiency, or increasing sickness absence and the associated high economic cost of these factors. This article presents the results of research on the condition of the study and work environment. It determines the factors influencing the shaping of indoor environmental conditions and presents the impact of the indoor environment on the quality of the people working there. The relationship between the basic parameters of the indoor microclimate and the level of satisfaction with the environmental conditions and its impact on the comfort of study and work is examined. Attention is paid to the impact of green solutions in buildings in order to improve the quality of life and efficiency in study areas and workplaces.
