Abstract
In order to find out indoor air quality (IAQ) condition at the Guilin public building, four office buildings’ IAQ had been investigated with the carry-home fast inspect instrument from November 2010 to September 2011 in Lingui New District. Based on the research data, IAQ in four public buildings in Guilin was evaluated using the decibel concept index method. The results show that SBS happens in three of the buildings. The main pollutants indoor are PM10 and HCHO. Due to the decibel concept, index method requires few assessment indexes; it is easy to operate; however, there will be a large deviation if some unmeasured parameter value is over proof. Regarding CO2, TVOC, and HCHO as chemical pollutant, evaluation index representatives are suitable to estimate IAQ when considering the condition of China. Comparatively, the composite index method may sometimes underestimate it.
