Abstract
At the present time, most Korean residential building depend on the radiant heating system. But this system leads to excessive heat supply by maintaining high level of floor temperature and creates a serious problem of energy overconsumption. In this study, therefore, suggest another or composite heating system that is better energy saving and more comfortable heating system by the mock-up test. And additionally have analysis about energy consumption and considered indoor heating distribution through CFD simulation. In the result, the existing radiant heating system is good for comfortable, but energy consumption is more worst than the air heating system. Therefore heating systems of apartment house are determined by heating zone's characteristics.
