The building to be examined has load capacity of cooling (259 kw), heating (316 kw) and geothermal capacity of cooling (333.8 kw) and heating (335.4 kw). In the process of design, first internal load and ventilation load of building were calculated with data such as insulation and finishing materials. Second, thermal conduction test was conducted for the installation of PE pipe for underground heat exchanger and water circulation for 2,882 min. Then heat exchanger quantity, drilled hole quantity and geothermal heat pump capacity were calculated with thermal conduction rate (2.83 W/mK). Third, geothermal circulating pump, hot and cold water circulating pump, expansion tank, buffer tank and apparatus were calculated with the estimated load. All equipments were arranged in machinery room and piping connected with each equipment. As a result of employing geothermal system to the building and comparing the system with existing urban gas energy consumption, it was found that the energy consumption and energy-saving rates of each season was varied. And this study confirmed the effect of energy saving effects of 7.1~37% compared to existing urban gas heating and cooling system. In addition, cooling tower to be installed on the front of the building resulted ill block noise and prevent civil complaint. Moreover, the effects of promoting the use of new and renewable energy to residents were also great.
Construction and maintenance of the buildings should be planned to prevent the defects in apartment houses. Therefore, defect in each process survey were analyzed by construction companies or management office, and the results are presented a follows: First, processes are roughly categorized into three groups such as construction, facilities, and electric field. The process in which most defects occurred in the construction field is followed by facilities and electricity. The total rates of defects are 71.78% in construction, 19.32% in facilities, and 8.90% in electricity. Second, the distribution rates of defects to be maintained were 20.37% in construction using wooden materials, 18.03% in floor hating, 12.79% in tiling, and 9.54% in paperhanging. The rates of defects found in facilities were 29.12% in bathing facilities, 45.64% in kitchen facilities, and 68.95% in lighting. Third, the rates of defects to be repaired were 4.37% in construction, 1.11% in facilities, and 0.14% in electricity, which show that the repair rare was very low except for construction.
