Sick building syndrome - A case study in a multistory centrally air-conditioned building in the Delhi City

A questionnaire study has been carried out to investigate the prevalence of SBS (Sick Building Syndrome) in a multistory centrally air-conditioned Airport Authority of India building in New Dehli city. The quantification of the users' perception about IAQ was done by converting their responses to a SBS score. A qualitative and quantitative analysis were then conducted. A direct relation between the average SBS score and CO2 concentration was found, clearly signifying the usefulness of SBS score in IAQ.
