Abstract:
For low-rise buildings, the heat loss through the ground
coupled floor is a significant load component. Studies
showed that the current simulation tools give dissimilar
results for the ground coupled heat transfer (GCHT) in
slab-on-grade constructions. This paper extends the
previous comparative work by comparing EnergyPlus
and DOE-2.1e results for GCHT based on a slab-ongrade
code house in a cold climate. Three GCHT
models were used in the study. These models were
Winkelmann’s (2002) model in DOE-2.1e,
Winkelmann’s model in EnergyPlus and EnergyPlus
with its GCHT calculator utility, Slab.
