Hi all,

I am interested in combined thermal/pollutant transport simulations to examine room concentrations of PM2.5 over time from indoor and outdoor sources.

I have read the NIST documentation on coupled thermal/contaminant simulations to EnergyPlus and TRNSYS. However, it's not immediately clear to me what the pros/cons of these couplings are, in comparison to the EnergyPlus generic contaminant model (GCM).

I have read Taylor et al's "Simulation of pollution transport in buildings: the importance of taking into account dynamic thermal effects" which shows relatively good agreement between the two methods.

Are the underlying contaminant transport calculations the same for both? Why might one choose on vs. the other?

Thank you!
