Abstract

This study examined the applicability of a prototypical apartment model at the unit-position level using weather-normalized city-gas consumption data for 2,212 households in five apartment complexes in Seoul. Building-level gas EUI and unit-position effects were compared with the model, showing differences of only 1.5–2.0%p in orientation-dependent relative gas EUI. At the unit-position level, both datasets showed the same consumption ranking of GS > GC > TS > TC > MS > MC, with an MAE of 4.24%p for the relative increase from MC. Analysis under different orientations and climate conditions showed that the unit-position ranking remained consistent, while the magnitude of relative differences varied with the consumption level of MC. These results demonstrate the applicability of the prototypical apartment model for evaluating relative gas consumption characteristics by unit position.
