The elevated water storage tanks highly crowded in the western region in Jeju island is an important landmark of Jeju island. This study examines the reasons that the elevated water storage tanks appeared in a high density. After examination, this study found that the elevated water storage tanks formed under the influences of climate, hydrogeologic structure, soil, topography and land use. In particular, the elevated water storage tanks in Jeju are closely related to the crapping system with which water has to be supplied using sprinkler due to well drained soil and hydrogeological characteristics. The results of this study show that elevated water storage tank landscape in the western region of Jeju island is an agricultural landscape particularly made in the course of farmers' adaptation to the natural environment of Jeju island.

This study is the survey of a transition procedure of building services systems(heat source, HVAC, water supply) through the survey of existing office buildings, building design documents. The preference & major consideration of system selection is the engineer's opinions. The results of this survey can be used in selection of building services system design. In this survey, "Hot & cold water generator system" and "single duct CAV+FCU system", "Elevated water tank system" are selected. The most important consideration in system selection is the energy saving in heat source system, and comfort in HVAC system, and water pressure in water supply system. They prefer "steam boiler+absorption chiller system" for heat source system, "steam boiler+ice thermal storage system", "hot & cold water generator system", "district heating+absorption chiller system" : "single duct CAV+FCU system" and "single duct VAV+convector system" for HVAC system: and "booster pump system" for water supply system.
