[EnergyPlus_Support] thermal mass versus insulation

["Emanuele Naboni" <emanuele.naboni@xxxxxxxxx>]

Gents,

I am running a simulation to understand for a residential building located
in Milan if is better to have an envelope with thermal mass or a light wall
(similar to passive house wall). Both wall have the same K=0.4w/hm2 °C.

The light wall gives better Energy consuptions performance in winter
season, the thermal mass during the summer.
Is this a reasenable result?

Might it be that the thermal mass during the winter absorbe part of the heat
from the HVAC?
Thanks in advance to anyone has experience on the field!
