摘要
以室内环境的空气品质以及声、光、热环境为研究对象,根据实测数据,建立不满意百分比指标PD(predicteddissatisfied),基于熵权理论对整个室内环境进行评价。在多因素的室内环境评价过程中,该方法在以实测数据确定评价指标的相对重要程度后,根据各评价对象之间某些评价指标重要度的差异,自动调节各种差异对评价过程的影响,合理的优化了评价过程。以某小区6户人家家庭环境的物理、化学因素测试的数据进行综合评价,其结果与实际情况相吻合。说明该方法所得到的评价结果具有说服力。
By taking the air quality, the sound, the light and the thermal conditions in indoor environment as the objects of study and according to the PD （predicted dissatisfied） indexes established by measured data, an indoor environment evaluation is made based on entropy weight theory. During multi-factor indoor environment evaluation process, this method determines the comparative importance of evaluating indexes according to the measured data, and automatically adjusts the influence of these difference on evaluating process according to the importance discrepancy of evaluating indexes between evaluation objects. And thus, the evaluating process is rationally optimized. By taking the physical and chemical data measured in the indoor environment of six households in a certain community as examples, a comprehensive evaluation is made on these data. The result shows that it is in accord with the actuality and the method is feasible.
