Buildings that are more than 10 years of age generally have considerable renovation/replacement costs due to the rapid deterioration of the systems composing those buildings. For public buildings in particular, which are national & social properties, considerable efforts are required not only to ensure the long life cycle and safety of the facilities, but also to reduce the necessary public expense. To address these, a renovation/replacement cost management system that manages invested maintenance cost and forecasting cost is constructed to establish a reasonable renovation/replacement planning and budget. System acceptability is verified through a pilot test targeting K-public corporation.

Older apartment houses to require energy saving because they use more energy than new apartment house that reflect government policies. However, existing apartment houses has many difficulties in saving energy because they do not have enough energy saving standards considering cost. In this paper, it analyzes the cost benefits and suggest method to improve the energy performance in existing apartment houses. For the cost benefit analysis, a DB at cost analysis was constructed and life cycle cost calculation and energy performance evaluation were performed by establishing target buildings. In order to improve the energy efficiency of existing apartment complexes using the evaluation results, two suggestions were suggested. First, in terms of initial investment cost, the case with only insulation was the largest benefit with an average of 2.52. The case of only window had the smallest benefit of 0.93. Second, in terms of life cycle costs, all cases were estimated to be less than 1, so that economic validity could not be secured. The case of only the insulation was the smallest with an average of 0.11, and the case of both the window and the insulation was the largest with an average of 0.30.

This study conducted a survey targeting baby boomers in the metropolitan area to determine their intention to move to a senior-friendly residential area. The survey results show that baby boomers in the metropolitan area are willing to move to senior-friendly residential areas. Those who wanted to move said that it was because of stable retirement life and senior-friendly welfare facilities. However, the reasons for not wishing to move were the lack of medical and welfare service facilities, lack of jobs, and inconvenience in public transportation. Lastly, it was found that senior-friendly residential areas prefer areas that are adjacent to the metropolitan area, have a well-established living area, and have convenient transportation.
