Hi all,

I am interested in combined thermal/pollutant transport simulations to examine room concentrations of PM2.5 and various gases over time resulting 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 compares GCM to standalone-CONTAM. However I haven't yet found sources comparing GCM to CONTAM/EnergyPlus coupling.

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

Thank you!

However I haven't yet found sources comparing GCM to CONTAM/EnergyPlus coupling.shows relatively good agreement between the two methods.
