The effect of perceived environment quality on comfort and productivity has been studied as the poor indoor microclimate quality can negatively affects the people performance. The occupants are likely to be less attentive and concentrate, which over time may lead to detrimental effects on higher productivity attainment. The objective of the present work is to extend the knowledge of the indoor environmental quality effects on performance and productivity. The aim of the work is the study of perceived indoor environment quality influence on the occupants´ productivity. This research work is focused on theoretical analysis, synthesis and confrontation of existing and obtained knowledge. On the base of this knowledge the methodology of research was suggested with emphasis to perceived indoor environment quality and related productivity. Experimental study was realized with the aid of software tool. The experiments were conducted in model study room. The positive effect of perceived indoor microclimate quality to performance and productivity of occupants was confirmed. There were evaluated the impact of the selected physical factors on the perceived indoor environmental quality during the testing process and the students´ performance. The optimal range of indoor microclimate parameters with the goal of achievement the highest productivity was determined. The results of the work confirmed the importance of economy perception concerning to complex solving indoor environment. The indoor environment design without respecting of cost balance and productivity make no sense. These results allow their immediate utilizing in related practice. It may also serve to students and professionals who are oriented on the indoor environment design. This work contributes to knowledge extension of special interdisciplinary area interactions.
