Re: [EnergyPlus_Support] thermal mass versus insulation



Our experience is that intenal mass has an small impact on energy consumption. 

Internal mass can sligthly reduce heating Energy consumption in buildings with high solar heat gains. 

It is also possible to get a higher consumption in a more massive building, if the heating system is off in the night. This is due to higher temperature inside the building. 

Here in spain architects use to think that internal mass is an effective measure to save Energy,  
But usually this is not reflected by simulations. 

I hope it helps.

Subject: [EnergyPlus_Support] thermal mass versus insulation

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!
