As buildings generally have become larger and more airtight, the ventilation rate has decreased further, causing insufficient ventilation which leads to moisture problems such as condensation, mold growth, reduction of thermal insulation performance and corrosion of building materials. In order to prevent moisture problems, it is essential to understand the thermal and hygric status of a climatic region. In this study, the hygrothermal environmental zone considering not only the thermal environment but also the hygric environment was derived by analyzing the climate environment in Korea. The hygrothermal environmental zone has the advantage of being able to take into account the hygrothermal environment of the unexplored regions and to cope with climate change by quantifying the thermal and hygric environmental indexes in each region. Finally, the long-term moisture risk of the building envelopes was evaluated. As the results, it is considered that the proposed hygrothermal environmental zone is appropriate and it is necessary to consider the hygric environment in order to secure the moisture stability of the building envelope.
