Reflecting upon noise reduction, temperature control appears as a way to give comfort to all people who enter the jury court. As a result, the air quality was compromised due to the cumulative effect of the concentration of carbon dioxide and other gases that are harmful to health, due to the large number of people, through breathing. With the lack of air conditioning equipment with the function of air renewal, the environment becomes even more dangerous, causing excessive yawning, malaise and even suffocation. The present study aimed to monitor CO2 concentrations, ambient temperature and relative air humidity inside a room in a public building, which uses artificial air conditioning. The collections were carried out in February 2022 from 9:00 am to 3:30 pm, in the morning and afternoon, using portable equipment. Values recommended by ANVISA Resolution No. 9 were used as a comparison parameter. The results gave rise to knowledge about the air quality in this environment, with CO2 concentrations ranging from 957 ppm at 9:27 am to 1157 ppm at 12:46 pm, being above the reference rate of 1000 ppm, the temperature (°C) between 25.19 and 27.00, within the standards and humidity (RH) between 59.83 and 69.13, above the reference rate. It is therefore advisable to implement simple measures such as opening doors and windows during the intervals between trials to renew the air, in order to ensure comfort, well-being for the occupants and the reduction of CO2 concentration, the great villain of the greenhouse effect.
