Diagnosis of indoor air quality and ventilation design utilizing expert system

This research is aimed to improve indoor air quality (IAQ) in the building by using the expert system (ES) based on the artificial intelligence (AI). The diagnosis tool of IAQ and ventilation design tool corresponding to 9 kinds of pollutants were developed. For diagnosis the concentration calculated from pollution generation rate and outdoor air is compared to the standard. For designing, the ventilation rate is provided from allowed concentration and pollutant generation rate. This paper explains the view of the systems corresponding to 11 rooms and some examples using “standard house” of AIJ(1) and “HASS102” of Japanese ventilation standard(2).
