“…One of the most important environmental parameters that need to be controlled is carbon dioxide and that can only be achieved through proper ventilation. Inadequate IAQ conditions in classrooms can lead to a reduction in children's performance of up to 30% [11]. (ii) Thermal comfort is the condition of mind that generates satisfaction with the thermal environment.…”

Decades ago, the only requirement to construct a building was to give men the right conditions for the execution of their work or leisure activities. With the development of knowledge about the internal and external environments of buildings, other requirements have been added such as the issue of user comfort. New construction techniques have been incorporated and new products have been created to improve internal environment comfort. This research addressed the importance of using indicators related to environmental comfort in sustainability assessment tools applied to school buildings. It also considered the importance of environmental issues for the good performance of human beings, and the harmonious coexistence of the comfort indicators indoor air quality, thermal comfort, visual comfort, acoustic comfort and ergonomic comfort based on data gathered in research carried out with users of high schools (only students). This research was carried out in two different cities of different countries, Guimarães (Portugal) and Juiz de Fora (Brazil), that have similar characteristics of teaching standards and climate conditions (temperature and air humidity). In this study, interviews were made through questionnaires and, later, the information collected was analyzed. This study demonstrates the need to include an ergonomic indicator for school buildings in sustainability assessment tools.

In the 1970s and 1980s, the effects of pollution in the atmosphere grew from a local to a global scale, affecting the entire planet. Consequently, economic and social issues began to be increasingly more connected with environmental protection. Several measures were taken towards environmental preservation, many of those related to the sustainable construction of buildings. This work intended to make a parallel between comfort indicators among different schools in Brazil, beginning with the specific analyses of schools in Juiz de Fora (Minas Gerais, MG), in the Southeast region, and in Macapá (Amapa, AP), in the Amazon or Northern region. This comparison between schools is made to demonstrate the need to adapt methodologies and certifications that promote sustainability in school buildings for each region of Brazil. Questionnaires about ergonomic, thermal, visual and acoustic comfort, and air quality, were applied in two high-school buildings in Juiz de Fora, Academia School and Santa Catarina School, and in two high schools in Macapá, Tiradentes School and Professor Gabriel Almeida Café school, to understand the difference between these two regions of Brazil regarding comfort conditions. A comparison between the results of the four schools was made, proving the necessity of the elaboration of a specific methodology for each Brazilian region.

“…In more than 50% of the time when the students were in the classroom, the CO 2 concentration reached a maximum value of about 3,600 ppmv at the end of the morning shift, indicating inadequate ventilation. Ghita and Catalina (2015) conducted a detailed research in three schools (new, old and a renewed building) from the Mateeşti (Vâlcea County, Romania) rural area. In all three schools the measured values varied between 2,000-3,000 ppmv, in certain situations the concentration was close to 5,000 ppmv (the old building recorded the highest values).…”

In today's modern society, people spend much of their time in closed spaces (at home, at work, at school etc.), the quality of the air inside these spaces being very important for the occupants' health. This study monitored the indoor air quality in classrooms, seminar and office rooms, within the Faculty of Environmental Science and Engineering from Cluj-Napoca and outside the building (the inner courtyard). Two air sampling campaigns were carried out, one during the cold period (March 2019), and the other during the warm period (April 2019). The monitored substances were: carbon dioxide (CO 2 ), particulate matter (PM 2.5 , PM 10 ), formaldehyde, total volatile organic compounds (TVOC) as well as the temperature and relative humidity of the studied rooms, respectively the outside courtyard, using BQ16 and BQ30 Trotec equipment's. The average values for CO 2 concentration exceeded the recommended 1,000 ppmv ASHRAE standard value, especially after a period when the rooms were not ventilated and the number of people inside increased. Concentrations of PM 2.5 and PM 10 were below the recommended ASHRAE standard value, of 25 µg/m 3 for PM 2.5 and 50 µg/m 3 for PM 10 , so indoor air quality is not inappropriate for this reason. Formaldehyde and TVOC concentrations measured in the monitored rooms, did not exceeded the recommended standard values. Their concentrations were lower outside than inside, so it can be considered that their source was an internal one and their concentrations increased as the number of people in the room increases. In the seminar room the CDI (Chronic Daily Intake) value for formaldehyde has the value 0.052 mg/kg·day, slightly exceeding the recommended value by U.S.EPA (1989), of 0.045 mg/kg·day.
