A new indoor air quality assessment system and its software tool

This article describes the features and operation of a new indoor air quality assessment system and its software tool named SRIBS-IAQ. The assessment system and its software tool were used in a case study to establish its practicality and performance. This assessment system is unique in the sense that it employs an optimization model called the grey model. We establish a set of Air Quality Objectives (AQOs) among which were five compulsive : HCHO, TVOC, C(6)H(6), NH(3) and radon, The others are optional: O(3). CO(2), CO, NO(2), PM10. microbe. It also includes the assessment of comprehensive environmental impacts such as combined toxicity of HCHO and TVOC and the database of Shanghai local meteorology, building materials and construction properties. Based on the different functional building, residence and office, this new indoor air quality assessment system use some scientific models to evaluate the main influence factors and its impact on human health, comfort and productivity in indoor environment, it also to predict the concentration and exposure rules in certain times. And then, in order to reflect the result directly, we use a positive score for this evaluation system. The application of a weighting system of the score was also afforded. Some scientific and reasonable control and improve measurements are put forwarded.
