Evaluates the indoor air quality and thermal comfort conditions in a newly decorated office building through continuous objective monitoring and subjective questionnaire surveys using a post-occupancy evaluation (POE). The results show that the indoor temperature and relative humidity of the building are low. The influence of occupants in the room on the indoor thermal environment is small. The concentration of CO2 is low, the average concentration of total volatile organic compounds (TVOC) does not exceed the limit of the code, the concentration of fine particulate matter (PM2.5) in some offices exceeds the limit, but the concentration of inhalable particulate matter (PM10) does not exceed the limit. The concentrations of PM2.5 and PM10 are less affected by human activities, and are mainly related to the concentration of outdoor particulate matter. The concentration of TVOC has a significant effect on the occupants’ assessment of indoor air quality, and it is the main parameter that cannot be ignored when establishing an evaluation model of indoor air quality for newly built buildings.
