The advent of an aging society has raised the necessity for housing development to meet the growing demands of baby boomers expected to act as the main consumers in the future housing market. This study aims to identify the characteristics of apartment houses favored by baby boomers in their post-retirement plans. Based on a literature review and survey, the study is targeted at a certain baby boom generation residing in mid- sized and large-sized apartments with a floor space of more than 30 pyeong in Gangnam, Seoul. The study reveals that baby boomers favor an active post-retirement life where they can enjoy proper leisure without considerable change in daily routines, and for that reason they choose an apartment house well equipped with neighboring, convenient facilities for their post-retirement. Their housing size shows a downward tendency in response to changes in economic conditions and number of family members living together. Health-related factors such as a comfortable natural environment and greenery also play a key role in their residence selection. Their regional preference is divided into the downtown and suburbs, and thus it will be necessary to satisfy the needs of these two consumer groups in the future housing market. This study lays the foundation for offering basic materials for the development and marketing of apartment houses.

Recently, the size of tiles used for bathroom walls in apartment houses is gradually increasing in size. The problem is that when these large-sized tiles are attached by the sticking method, due to the nature of the method, there is a concern about the stability of the attachment to the part (pupil) where the tile and the adhesive are not attached. The problem is serious as it leads to lawsuits in the outbreak court. In addition, it is urgent to verify the adhesion stability of the sticking method because secondary damage occurs due to a safety accident caused by the falling of the tile. Ministry of Land, Infrastructure and Transport [Investigation of defects in apartment houses, calculation of repair cost and defect determination criteria] ① The tile adhesion strength is 0.39N/mm² or more and ② It is specified to fill 80% or more of the base area of the tile backside, but this is currently trendy. It is considered that large-sized tiles need to be verified from multiple angles, and as part of that, we intend to verify the adhesion stability according to the area to be attached to large-sized tiles.

To design mechanical ventilation for bathroom of apartment houses where air supply and exhaust are taken into consideration, mock-ups of ventilation systems, widely used in bathroom of apartment houses with an area of 100$\textrm{m}^2$, were made and installed in a laboratory. These ventilation mock-ups were available for control of air supply and exhaust, and the sizes of supply openings were 40cm${\times}$1cm, 40cm${\times}$3cm, and 40cm${\times}$5cm. They were installed at five positions, spaced 45cm at a height of 5cm from the floor. The exhaust fan was designed for its operating voltage to be set to five steps(100V, 130V, 150V, 180V and 220V) in order to control its air flow rates. When the size and position of each supply opening were changed with the wind velocity of the exhaust fan set to the step 5, the ventilation rates were measured and analyzed by the concentration decay method of tracer gas method, in order to present an efficient mechanical ventilation system. The results of the study revealed that the ventilations rates would increase in the presence of supply openings, compared to the absence of supply openings, and that the larger the size of the supply opening, the more the ventilation rates. Therefore, it was found necessary to take air supply into consideration.

서울시 25개 자치구를 대상으로 주택 유형 및 세대구성원 등 여러 요인별로 1인당1일 수돗물 사용량(lpcd)을 비교 분석하였다. 조사대상인 표본으로부터 서울시 전체 모집단의 수돗물 사용량을 추정하여 제시하였다. 이를 위하여 서울시 주택유형 비율 통계자료를 이용하였으며, 실제 비율을 표본 결과에 적용하여 서울시 전체의 1인1일 수돗물 사용량을 추정하였다. 세대구성원수가 증가할수록 1인 1일 수돗물사용량은 감소하고 있다. 이는 세대구성원수와 상관없이 한 세대가 1인인 경우에도 취사, 세탁 등에 공통으로 사용하는 물의 양이 있기 때문인 것으로 판단된다. 아파트의 경우 세대구성원수 증가에 따른 평균적인 수돗물사용량 감소량은 1인세대에서 2인세대로 변할 때 233 L(47.6%)이며, 2인세대에서 3인세대로 변할 때 62 L(20.8%)이며, 3인세대에서 4인세대로 변할 때 32 L (16.9%)이며 4인세대에서 5인세대로 변할 때 18 L(9.0%)로 나타났다. 선형회귀식을 구하여 검토한 결과, 세대구성원이 1인증가함에 따라 감소율이 12%씩 감소하는 것을 보여주고 있다.

This study was conducted to calculate the LCC of a apartment complex with a type of heating system, district heating and cogeneration system. For the purpose of analyzing LCC according to size of apartment complex, 500, 1,500 and 4,000 houses of model apartment selected. This research performs design of heating system and the life cycle cost analysis including an initial cost, energy cost, maintenance and operation cost, replacement cost and renovation cost during the project period(15years). According to the calculated results, 1) Initial cost of cogeneration system with 500, 1500 and 4000 houses is higher than district heating system each of 20%, 13%, 12%. 2) In case of cogeneration system, the payback period by electric generation is 5.21, 4.92 and 4.47 years and saving cost was calculated 29 billion won, 94 billion won and 262 billion won after payback period. 3) Cogeneration system LCC was 1.12, 1.07 and 1.06 times larger than district system with the size of apartment complex. According to the case of this study district heating system is more efficient than cogeneration system in terms of the reduction of LCC. 4) Gas Engine Co-generation System is more efficient than other systems because it can collect progressive part from electric charge progressive stage system. However, the efficiency is decreasing because of raising of fuel bills(LNG) and lowering of power rate for house use. Especially the engine is foreign-made so the cost of maintenance and repair is high and the technical expert is short. 5) District heating is also affected by fuel bills so we should improve energy efficiency through recovering of waste heat(incineration heat, etc.). Also, we should supply district cooling on the pattern of heat using of let the temperature high in winter and low in summer.

The Brands which were selected for this study ranked from first to fifth in the contractor ranking and now account for 64 percent of the apartments in sale in Seoul and Gyeonggi Province. In addition, the size between $99m^2$ and $165m^2$ were selected, because it was most preferred at the 2011 survey for user preference on the size of apartment. As this study is for the colors shown on the monintor, colors were extracted from the images of web site with L*, a*, b*. And then, they were converted to Munsell values through computer program, which values were used to identify the color characteristics of hue, tone and to apply the theory of Moon Spencer. The result of the study on the color characteristics of the kitchen and dining room of the five brands' apartments is as follows. Regarding the color use, most of the brands used Y and YR color while as the accent color, P, PB and G were used. This result of main color use for hue was same as the guideline by the literature review, but color for tone showed the difference between brands and the difference between sizes. Next, regarding the color combination, first ambiguity of color harmony was shown the most. And the larger the size was, the more the contrast of color harmony was shown. It means that the color tone had close relation with the sizes of households.
