RE: [EnergyPlus_Support] Re: Material & Material:NoMass





Thanks Linda for answer,

Let me explain what I understood from you, correct me if I'm not,

You mean that if I used R value , the thermal mass value which it should have been stored in the materials will act as heat gain inside the building during summer which leads for more heat  load?

 

best regards,

Ameen Mattar

If you choose the R only (nomass) materials, you will lose the ability for your building to have thermal mass "storage" in its materials.

Maybe my question wasn't clear 100%.
I mean what is the benefit of evaluating of transient conducion effects in "material" object? and if I used "Material:Nomass" what am I losing practically if it's assuming steady state heat conduction?
Thanks
