Case Study of Thermal Comfort, Lighting Conditions and Productivity at Two Classrooms of Poznań University of Technology

Abstract The paper analyses subjective sensations of thermal comfort, lighting conditions and self-reported productivity of 51 students of Poznań Univeristy of Technology (Poland). The study took place in the spring and was based on the use of anonymous questionnaires with questions on thermal sensations, acceptability and preferences as well as the students’ assessment of their current productivity and lighting conditions. The test results indicate that the overwhelming majority was satisfied with thermal environment and lighting conditions in the rooms. Their general sensations were also largely positive, while self – reported productivity was generally assessed to be normal.
