5、ty of Kosice, Vysokoskolska 4, 040 01, Slovakia Abstract The experimental monitoring of indoor air temperature, relative humidity, and carbon dioxide were carried out for the investigation of real state of the indoor en

6、vironment in selected classrooms during winter and summer semester. Concurrently subjective evaluation by questionnaire was conducted. The average value of indoor air temperature was 23.1°C, relative humidity 41.1

7、5 % and CO2 concentration 1315.88 ppm in winter semester. The average value of indoor air temperature was 24.8°C, relative humidity 36.28% and CO2 concentration 1094.62 ppm in summer semester. Results of objective

8、and subjective assessment show that it is important to propose optimization measures for reducing the CO2concentrations and thermal load in summer period. © 2017 The Authors. Published by Elsevier Ltd. Peer-revi

12、 496 – 503 In the first phase of the research nine measurements were carried out during the winter semester. Floor area of the classroom are 12.5 x 5.8m. It is important to note that classroom is located in the attic of

13、the building on the west side. Four groups of students had consecutively lesson for 45 minutes and breaks. During breaks they opened windows to ventilate the room and reduce the CO2 concentrations. The classroom with v

14、olume of 191.4 m3and capacity up to 38 persons was naturally ventilated for 5 minutes (door and 5 windows were opened) before measurement and after each lesson. Then all windows and door were closed (during the lesson)

15、. No forced ventilation or air-conditioning system was used in the classroom. In the classroom, there were 10 windows and 10 skylights, 16 desks from particleboard, 32 plastic chairs, blackboard for chalk, data project

16、or, and the flooring from OSB. Investigation were performed through winter semester and were conducted during four consecutively lessons for 13 weeks. In this study are discussed results from 9 weeks. Number of occupan

17、ts were 42 – 50 for each day divided to four groups. Average number of students in one group is 13, three of them were smokers. The average age of students was 19.5 years. The second stage of the research took place du

18、ring the summer semester. Investigation was performed in a classroom on the same floor like during the first stage of research work. Dimensions of room are 11 m x 5.8m. Classroom is placed in the attic of the building o

19、n the north side. The classroom was equipped with 19 desks from particleboard, 38 plastic chairs, blackboard for chalk, 8 computers, and one PC projector. In the classroom, there were 10 windows and 10 skylights, one d

20、oor, lime plasters with water based paint on the walls, and flooring from OSB. All windows and doors were opened for 5 minutes before the lecture, and then they were closed and re- opened. No forced ventilation or air-c

21、onditioning system was used in the classroom. Investigation was performed during summer semester. This study presents results only for 8 weeks. The number of students in one group was 10, one of them was a smoker. The

22、average age of students was 24 years. Measurements conducted during lectures (90 minutes), 5 minutes breaks and seminars (45 minutes). Overall they lasted 140 minutes. 2.2. Subjective assessment Subjective measurements

23、 were carried out through questionnaires at the beginning and at the end of each lesson. Subjective assessment using questionnaire was carried out in the university classrooms for the purpose of evaluation the influenc

24、e of indoor environmental parameters on students’ performance. Respondents expressed through a questionnaire their feelings from thermal and odor comfort and from overall perception of air quality. Concurrently measure

25、ments of above mentioned factors were carried out. Scales used in the questionnaire are shown in Tab. 1. Table 1. Scales used in the questionnaire. The perception The sensational evaluation Air temperature 3 hot 2 warm
