The contamination of air inside non-residential buildings by chemical substances remains unclear due to lack of investigation and the diverse uses of such buildings. The authors therefore studied the general trend of air quality in government buildings. Multiple regression analyses were conducted to identify the correlations among pollutant concentrations, air temperature, relative humidity, and building age, and the following results were obtained: * The formaldehyde concentrations measured in winter were low in general. *The concentrations measured in summer were also low in Hokkaido, Tohoku, and Tsukuba, which are relatively cool areas. * The results of multiple regression analysis showed that air temperature had almost the same influence as that obtained by Inoue's equation, whereas relative humidity had a slightly greater influence. * The results of multiple regression analyses showed that the concentrations decreased with building age. * The influence of surface materials and amount of ventilation could not be identified. * The air temperature, relative humidity, and building age were classified into several levels, and a multiple regression analysis conducted for each level with the average concentrations for each level as dependent variables yielded coefficients of determination far higher than those obtained without dividing the data into levels.
