The Indian Institute of Technology Delhi (IIT Delhi) conducted a survey on the state of indoor air quality in various buildings in Delhi including in schools, colleges, hospitals, restaurants, residential buildings and cinemas in 2020. The IIT Delhi survey was conducted in order to find out the quality of air that we breathe indoors in different building spaces and to generate public awareness about the importance of indoor environment.
The survey was done by Centre of Excellence for Research on Clean Air (CERCA), IIT Delhi; Society for Indoor Environment (SIE), and Kaiterra, an air quality instrument company.
As per the findings of the Project MAQUID (Monitoring of Air Quality in Urban Indoors in Delhi) released today, on February 19, said that the educational institutes including schools and colleges tops the list for high particulate matter (PM) concentration. The carbon dioxide levels are also recorded high in hospitals, colleges, offices and in restaurants. This, the survey says, is due to higher occupancy and inadequate ventilation. Though schools too have higher occupancy but all the selected schools were naturally ventilated so carbon dioxide levels are within the permissible limits except one or two schools as defined by ASHRAE, an IIT Delhi statement issued in this regard said.
