Summary

A systematic study of indoor air quality (IAQ)was conducted at four different sites of an academic institution, Indian Institute of Technology, Delhi. The study involved monitoring of carbon dioxide, nitrogen dioxide, sulphur dioxide and total suspended particulate. CO2 is taken as an index for evaluating IAQ. A direct relation is found to exist between occupancy level and CO2 concentration. The study showed that the critical factor for IAQ for naturally ventilated buildings is not the total window area but the window area per occupant and window area per unit floor area. Prevalence of "stack effect" is also observed at various sites.
