【摘要】 目的探讨评价办公楼室内空气质量科学的综合评价方法。方法分析了室内空气质量综合评价中评价指标、评价标准和权重系数3个基本要素。采用大气污染物浓度的背景值为评价标准。对不同办公楼内变异系数大的污染物指标赋予较大权重。用复相关系数代表污染物指标的独立性。以变异系数和复相关系数为基础用公式计算权重系数,并用此方法分析了已发表的某文献中报道的4栋办公楼室内空气CO2、CO、IP、细菌总数、甲醛、NO2和SO2的浓度,进行空气质量综合评价。结果用该方法计算出上述指标的权重系数分别为0.244、0.083、0.112、0.091、0.232、0.113和0.125,其评价结果比原报道的结果更科学合理。结论该评价方法应用于办公楼室内空气质量的综合评价具有较高的灵敏度。更多还原

【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.更多还原
