Various attempts have been made to solve the condensation problem by using existing building materials. However, passive condensation prevention material has difficulty responding to indoor dew point temperatures that change depending on the comfort range of occupants. It is difficult to prevent indoor air quality deterioration because of mold and bacteria as condensation occurs repeatedly under certain outdoor air conditions. If thermoelectric technology that can immediately respond to a wide range of temperature changes is used in the condensation prevention material, the condensation risk can be eliminated in a building. Accordingly, in this study, it was derived that areas where the indoor wall surface temperature in winter fell below the dew point temperature with operating time. Based on the simulation results, it was analyzed the applicability of active condensation prevention material using thermoelectric module, which can flexibly respond to the condensation risk according to the changes of indoor and outdoor temperature and humidity, in building systems. The average daily power consumption of thermoelectric elements per unit area was analyzed as 727.20 Wh/m2/day, 1,249.72 Wh/m2/day, and 1,087.61 Wh/m2/day at the side wall, top and bottom of the front wall. The annual power consumption in one apartment unit was 16.65 kWh/year at the side wall, 28.61 kWh/year at the top of the front wall, and 24.90 kWh/year at the bottom of the front wall. Considering the health of occupants, such as mold and bacteria caused by continued condensation, thermoelectric active condensation prevention material is expected to have excellent economic feasibility.
