This study sought to design a low-energy Hanok house through the PHPP energy simulation program. The goal is to retain the spirit of Hanok, a traditional Korean house style, and spread the adoption of the Hanok style. Using the standard drawings of the wood-frame house and the Hanok, the analysis of the heat loss of each element and the annual heat demand showed that the Hanok had about six times higher energy demand, and the heat loss was mostly associated with the envelope. As a result of applying to the Hanok principles in the same way as the insulation condition of a modern wood-frame house, the analysis showed an opportunity for about an 80% energy reduction. The need for design standards for the development of low-energy Hanok was confirmed.
