Air quality has a major impact on human health, especially inside buildings with an artificial climate. In closed environments, which contain a low rate of air renewal, the concentration of chemical and biological contaminants increases considerably. High concentrations of these contaminants can cause serious infectious diseases. In this context, the present study aimed to develop a Maintenance, Operation and Control Plan – MOCP applied to the air conditioners of selected sample points; laboratory 06, classroom 07 and classroom 26, sampling points 1, 2 and 3 respectively, of the Reitor Rezende de Ribeiro Rezende building at the Centro Universitário do Distrito Federal - UDF based on the analysis of indoor air quality-IAQ, in comparison with the rules and regulations of ANVISA and Law No. 13,589/2018, which provides for the mandatory preparation of a MOCP for environments with artificial air conditioning. Data were collected at the three selected sampling points and at the building parking lot between the months of November 2019 and March 2020 and a MOCP was proposed for the air conditioners installed at the respective points. The analysis of temperature, air humidity, air speed, chemical and microbiological was carried out following the methodology contained in the recommendations contained in ANVISA Resolution nº 09/2003, the results of the temperature verification varied between 22.7 °C and 25.20 °C, the results of humidity verification ranged between 28.30% and 68.0%, the air velocity at all all sampling points remained below 0.25 m/s, the number of colony forming units (CFU) of fungi were obtained between 45.0- 155.5 CFU/m³, the aerodispersoid concentration was maintained at 65 µg / m³ in all sample points and the carbon dioxide concentrations were 509.00 ppm, 633.00 ppm and 517.00 ppm. Sampling point 01 presented all results of physical parameters outside the recommendation of ANVISA, while results of sample points 02 and 03 varied during the two collections being within, below and above the recommendation of ANVISA. The analysis of these data supported the elaboration of the PMOC for the selected sampling points within the UDF, which in the future may be implemented in the entire 4R building, since these data are directly linked to indoor air quality, which are fundamental for the maintenance of equipment and for the preservation and wellbeing of human health.
