thermal mass in type 56

["Sakellari Dimitra" <dimitra@xxxxxxxxxx>]

Dear TRNSYS users,
I am using type 56 in order to calculate the thermal behavior of
a building that is served by an exhaust-air heat pump which
is modelled in EES. So far I get satisfying results except of one case:

I get the same zone temperature variations for two zones
with the same h-values but with different constructions (lets say
a massive and a lightweight).

Shouldn't the thermal mass of the construction affect differently
the temperature profiles in cases of fast changing loads?

Is there any way to calculate the time-constant of different 
constructions?

I would be grateful if anyone could help me.

Best Regards
Dimitra
