[EnergyPlus_Support] Thermal mass

dear E+ users,

I've modelize an office building (around 500m²) which is heated with electric convective baseboards and I think that thermal masses are underestimate. Temperature variations are too quick, until three degrees in ten minutes. 

I did several tests :

- addind internal thermal mass : temperature falling is slower but the rise of temperature is almost the same. Have you exemple of realistic thermal masses for office building ?

- use capacity multiplier or change the zone volume. It seems that use a capacity multiplier 2 or multiply by 2 zone volumes give different results. It's normal ?

Thanks,

Camille
