Study on indoor air quality of a newly built student dormitory in a university in Shenyang

During the heating season, a questionnaire survey was conducted among the test-occupancy staff of a newly built dormitory in a university in Shenyang, Liaoning Province, and the indoor air environment parameters of four dormitories were continuously monitored for 24h. The results show that the test residents have low satisfaction with the indoor air environment. The measured results show that the temperature of the four dormitories with high indoor air temperature ranges from 25.8 ℃ to 29.3℃, indoor air humidity meets the standard requirements, indoor CO2 and PM2.5 concentrations exceed the standard seriously, and HCHO and TVOC concentrations exceed the standard for a small amount of time.
