Abstract

Although reasonable IAQ pre-assessment becomes a high priority in modern building design, there have been significant challenges in scaling up building material emissions from laboratory results. The measured concentrations in actual large spaces were mostly quite lower than the predicted and did not decay as models suggested, often posing more than 50% discrepancy. The present study systematically identify the sink/source effect of material emissions in material mixture scenarios, and effectively reflect the major sink/source effect in scaling up small-scale emission measurements for more accurate IAQ evaluations in full-scale spaces.
