One of the most critical reasons for the issue is that Hanok lack usability and are difficult to maintain as a public facilities. Therefore, it is improvement of the usability of Hanok is needed for them to be accepted as public buildings and to set up the maintenance strategy for the style of the wooden structure. This research has defined public buildings in Hanok and classified them into three types according to structural standards. Then, this study analyzed the characteristics of each type, and suggested a checklist for Hanok usability, employing it to analyze the most recent exemplar Hanoks built as results in the governmental research project, monitored them in aspects of the facility management focused on the wooden structure and suggested strategies for sustainability by deriving eight factors in usability and another eight major types of defects to review the current status of the maintenance for the wooden structure. Finally, this study proposed the main direction for Hanok maintenance to establish its strategies for sustainability. Keywords: Hanok; Korean traditional building; public facilities; Han style; usability; assessment system; maintenance strategy; sustainability 1. Introduction Recently, the awareness of environmentally-friendly buildings, nature-friendly urban environment, and sustainable settlement for residents has increased when compared to the past. Hanok, Korean traditional buildings, are mainly used for residential facilities such as houses and accommodations, while inactively applied at public buildings in comparison [1]. Therefore, various attempts for Hanok to be a crucial type on non-residential architecture have been considered through empowering the usability of Hanok. In addition, maintenance and operation are quite important for the type of the wooden structure like Hanok to be more functional and sustainable as the multi-purposed facility for multiple users [2,3]. The purpose of this study is, therefore, to propose evaluation indexes for the usability of Hanok public buildings based on classifications of structural composition and to suggest the main strategies for maintenance operation with monitoring recently-built public facilities in the style of Hanok. For this study, nine target buildings have been selected and analyzed with field surveys using professional devices and monitoring know-hows for a year from November 2017 to November 2018. All of them were built as prototyped testbeds of Korean traditional public facilities by the precedent R&D projects supported by Ministry of Land and Transport Affairs of Korean Government. The range of Hanok to be analyzed in this study is in the building style with Korean traditional characteristics and elements—especially merged with recent technologies, structures, and materials for contemporary Buildings 2019, 9, 11; doi:10.3390/buildings9010011 www.mdpi.com/journal/buildings Buildings 2019, 9, 11 2 of 14 BuildingsBuildingsBuildings 2019 2019 2019, ,9 9 FOR, FOR9 FOR PEER PEER PEER REVIEW REVIEW REVIEW 22 2 use.
