[EnergyPlus_Support] Re: Thermal mass

Camille,
First thing I could think of is, check your inner and outter layers, if you switch them, and the isolation layer is on the inside, adding thermal mass wouldn't be much effective and you'll notice a very quick response on temperature rise as you describe.
