Development and Validation of a Multizone Model for Overall Indoor Air Environment Prediction

Many factors can affect the indoor air environment of residential buildings. The most important factors are airflow, air temperature, air humidity, and air contaminant concentration. An indoor air quality analysis that includes the important factors (temperature, humidity, airflow, and concentration) simultaneously, is appropriately entitled ‘overall indoor air environment analysis’. A dynamic model to describe the overall indoor air environment and to determine its variations in a multizone space is proposed. The model analysis was applied to a typical apartment with five rooms on the campus in Yunlin, Taiwan, to compare the overall indoor air environment inferred from experimental data with simulated results in multizone spaces. There was an average agreement between the model and the measurements to within 8% variation.
