Pollution concentrations in buildings.

Pollutants in a substantial number of buildings have now been investigated by public and private agencies. The archive of data on indoor pollutant levels observed in office buildings under conditions of normal operation and occupancy are reviewed using a computer based Building Performance Database. Representative values of 153 pollutants as well as detailed frequency distributions of commonly measured pollutants and of temperature and humidity are presented. These distributions may offer architects and engineers a means to predict pollutant patterns to be expected in new buildings as well as provide a standard against which pollution patterns in individual buildings can be evaluated.
