[Bldg-sim] Internal Mass Estimations for Grocery Stores

[Herrmann, Lesley]

Hello,

Are there any known resources that provide internal mass estimates (mass/floor area) for energy modeling of big-box commercial retail stores, particularly of the grocery store type?  Obviously, internal mass estimations have a significant impact on HVAC energy consumption and, as I am experiencing, the default internal mass amounts in the EnergyPlus reference buildings tend to be an underestimate for retail stores.

Thanks!
