The apartment buildings were hard to emission of water vapor by reduced infiltration. The purpose of this study was to investigate the generation of indoor temperature and humidity in the recent construction of small size apartment buildings. The temperature and humidity were measured in 3 apartments in Seongnam and Daejeon city. During the winter indoor temperature and relative humidity were measured ranged from 20 to $24^{\circ}C$ and 40 to 60%. Generated humidity caused by various characteristics of the residents, rather than external influences. Compare daytime (6:00 to 22:00) and nighttime (22:00 to 6:00), the temperature is low and absolute humidity is high at nighttime. Condensation is likely to occur at nighttime. Using the cumulative relative frequency and absolute humidity, small apartments design criteria (temperature, relative humidity) can be set.
