As the largest internet enterprise in Korea, Naver has an increasing demand of cloud services. We are inspired by the World Heritage Site of Korea, the Hahoe folk village, which was built within the embracement of mountains. The scheme takes the metaphor of the village and develops into a "learning community" protected by the data. Cooperating with consultants, we take on the technical challenges of data center creatively to achieve an integrated solution that is efficient and sustainable.
