Variables factor map of the principal component analysis on THM air concentrations (dimensions 1 & 2: 96% of total variance). Total THM was set as illustrative variable. S7 Equation S1. Determination of air exchange rate (AER) from CO2 decay sequences. Air Exchange Rate can be determined based on decay sequences of CO2 concentration. We assume that each decay sequence corresponds to absence of occupants in the instrumented room. If windows are open, this assumption is not valid and real AER is underestimated. However, given the duration of windows opening (minutes) compared do the sampling period (5 days), we assume that windows opening is negligible. Under these assumptions, AER can be determined based on CO2 concentration according to : πΏπ (πΆππ’π‘ − πΆπππ ) 0 (πΆππ’π‘ − πΆπππ ) = −ο¬π‘ With: Cout : outdoor CO2 concentration (ppm), assumed to be constant at 400 ppm Cind : indoor measured CO2 concentration (ppm) C0ind : indoor initial CO2 concentration (ppm) λ : Air Exchange Rate (vol/hour) t : time (hours) S8
