Abstract:
Objective To explore the method for scientific and comprehensive evaluation on indoor air quality of office building.Methods Three elements viz evaluation indexes,evaluation standards and weight coefficient in comprehensive evalu-ation on indoor air quality were analyzed.The background concentrations of ambient air pollutants were used as evaluation stan-dards.The data on indexes of indoor air pollutants with higher coefficient of variations were calculated by adding higher weight coefficients.The multiple correlation coefficients were used as the independence of the indexes of indoor air pollutants.The weight coefficients of the indexes of indoor air pollutants were calculated using the special formula based on the coefficient of variation and multiple correlation coefficient.This method was tried out ,as a comparative study for the comprehensive evaluation of indoor air quality based on the data on the concen trations of CO 2 ,CO,IP,total count of bacteria,the concentration of formaldehyde,NO 2 and SO 2 ,in indoor air of4office building reported in a certain published article.Results In the above or-der,the weight coefficients of air pollutants mentioned above calculated by this method were0.244,0.083,0.112,0.091,0.232,0.113and0.125,respectively.The evaluation result obtained by this method was more scientific and reasonable than that by the original report.Conclusion This method revealed higher sensitivity in the comprehensive evaluation on indoor air quality in office buildings.
