Spatial and seasonal variation of air quality in different microenvironments of a technical university in India

The present study aims to assess spatial and seasonal variations of indoor air quality (IAQ) among ten different indoor microenvironments of a technical university in India. Particulate matters (PM10 and PM2.5), total volatile organic compounds (TVOCs), carbon dioxide (CO2), and indoor environmental...

Description
Summary:The present study aims to assess spatial and seasonal variations of indoor air quality (IAQ) among ten different indoor microenvironments of a technical university in India. Particulate matters (PM10 and PM2.5), total volatile organic compounds (TVOCs), carbon dioxide (CO2), and indoor environmental quality (IEQ) indicators (i.e. temperature, relative humidity, and ventilation) were monitored during monsoon, winter and summer seasons from August 2018 to June 2019. The occupants’ perception about IAQ of studied microenvironments was analysed from 137 valid responses. The IAQ was found varying significantly (P
