Hello-
I am curious to know if anyone is aware of research or other work that
has investigated the impact of including the mass of the wood or
steel-framed cavity/insulation layer in the opaque surface definitions
of whole building energy models.
I am aware of ASHRAE RP-1145, which outlines a method for developing
"equivalent wall" models of various assemblies, and appears to include
the mass of the framing/insulation layer. However, this research does
not appear to evaluate the impact of mass of this one material layer
separately. I believe it is common to account for mass of other layers,
particularly concrete/masonry, but my experience is the cavity layer is
only simulated with thermal resistance and no mass.
Any leads would be appreciated.
Thanks,
David
Dear David,
My research has highlighted this as an area requiring further investigation.
We have three funding proposals at various stages, and all include further
research in thermal mass.
