This study analyzes the design and application process of Frost Protected Shallow Foundations (FPSF) developed and applied in Northern Europe and the United States, while analyzing the institutional circumstances that make it difficult to introduce FPSF in Korea. Currently, the foundation design code in Korea stipulates that the foundation should be placed below the frost depth to prevent freezing, which results in deep excavation and high construction costs. However, FPSF provides a cost-effective and energy-efficient alternative by raising the frost line and minimizing frost penetration by utilizing insulation. In Northern Europe, FPSF has been established since the mid-20th century through experimental research and practical applications using high-performance insulation. In the United States, the adoption of FPSF has expanded since the early 2000s, with clear design guidelines provided through standards such as ASCE 32-01 and major building codes such as IRC and IBC. On the other hand, in Korea, there is no FPSF design code suitable for the local climate environment. Therefore, this study emphasizes the need to develop FPSF design guidelines that take into account Korea's environmental conditions, and can be used as basic data for related policies and research and development.
