EnergyPlus vs DOE-2: The Effect of Ground Coupling on Heating and Cooling Energy Consumption of a Slab-On-Grade Code House in a Cold Climate
MetadataShow full item record
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.
