Remodeling of apartment houses has been increasing recently and residents have chosen to extend the balcony along with the legalization of balcony extension in apartment houses. Balcony extension provides residents more space, however, it has been investigated that balcony extension increases construction cost, heating and cooling cost and decreases sound insulation performance. Therefore, this study focuses on developing a decision making index for residents in remodeling required apartment houses. The suggested methodology involves surveying actual residents, survey analysis by AHP and decision model development using logistic regression analysis.

The purpose of this study is to find the current problems of using balcony in apartment. For this study, 255 subjects who are resided in economically sized apartment housings were selected. The major results of this study were ; 1) The front balcony was used as arrangement space a laundry drier and a flowerpot table. On the other hand, the rear balcony was used as storage space for a kind of washing powder and receptacle, kim-chi jar and storage container for food etc. 2) The most dissatisfactory respect on the balcony is the width of space. 3) The shelves were often used as storage facilities.

The former studies for expanding a balcony space were tend to be focused on only quantitative aspects. In this study, the characteristics of balcony space on thermal on vironment in apartment house were analysed. First, the effect of the balcony space on thermal environment of living space was analysed by field measurement. Second, the temperature distribution of the bedroom and heating/cooling load with the balcony expansion were analysed by numerical simulation.

The purpose of this study was to analyze the type of extended-balcony floor plan which has been reflected as a various forms after making amendment to the apartment extended-balcony legislation on December 2005 and to understand the design tendency of housing unit plan and the characteristic of living space planning by the type of size(pyeong) and extension. The objects of analysis and the plans are 333 example(235 of $84m^2$, 98 of $59m^2$) from the LH corporation competition. The design tendency of balcony space after extension is as follows; First, a type of extension for simple area to increase the area of room adjacent to balcony through balcony extension. Second, a type of functional reinforcement for private room to separate the mixed function followed by strengthening the individual function of the private room. Third, a type of ${\alpha}$-room to play new functions as hobby room, study room, soho-type room with working from home by extending balcony. Fourth, a integrated type to increase flexible efficiency of bed room, living room and kitchen by integrating extended-balcony from the flexible plan. Along with the evaluation of living style through user's environment-behavior research and the counterplan for evacuation space, indoor thermal environment and space for fulfilling the original function of balcony should be proposed in the future study.

복층이 있는 공간의 음향 특성을 계산식, 시뮬레이션 및 실측을 통해 비교해 보았다. 언더발코니 스피커의 바로 뒤 지역은 메인스피커와 딜레이 차이가 생기며, 중/저음 부분에서 충분한 음압저하가 이뤄지지 않아 컴필터링(Comb-Filtering) 현상이 크게 발생하게 된다. 또한 언더발코니 스피커의 바로 하부 지역은 스피커와 거리가 2~3m 내외로 언더발코니 스피커의 음압이 메인 스피커보다 커져 강대상과 음상일치가 깨지게 된다. 언더발코니 스피커에서 5~6m 이상 벗어나는 지역은 음의 역자승법칙에 따라 언더발코니 스피커 하부 지역보다 10dB이상 차이가 발생하며, 메인스피커에서도 중/고역 주파수(Mid/High Frequency) 음이 유입되지 않아 주파수별 음압 편차가 크게 발생하여 집중도가 떨어지게 된다. 이러한 음향 문제를 최소화하기 위해서 메인스피커의 위치 및 출력에 따른 언더발코니 스피커의 적절한 배치와 출력이 요청된다. 발코니 하부 지역을 더 쾌적한 음향 환경으로 개선하기 위해서는 언더발코니 스피커에 대한 적절한 음향설계 방향이 제시되어야 한다.

In order to prevent incoming solar radiation, it is necessary to study about blinds' blocking out effects of heat that are installed at the balcony at an apartment house. To figure out the heating effects from the windows, a study for indoor thermal environment according to the location of blinds is also needed. In order to find out the changes of indoor thermal environment, we'll compare models of a house building with or without Venetian blinds: one place has an extended living room removing a balcony and another one has a normal balcony. The result is as follows. Without blinds, the place with an extended living room has benefits for saving heat compare to the place with a normal balcony. It's because the warm air heated by the incoming solar radiation moves into the living room through convection current and radiation which causes an increase of the indoor temperature. At an extended living room, the temperature difference from outside and inside, when blinds were installed inside, was $1.9^{\circ}C$ while it was $0.6^{\circ}C$ when the blinds were installed at outside of the balcony. It is evaluated that setting up the blind outside prevents much heat. At the space with a normal balcony, installing blinds at living room windows can save much heat compare to installing blinds at windows at the balcony. The indoor temperature was low when blinds were installed. It can be said that blinds block heat from the incoming solar radiation. Moreover, when blinds are installed, there is a big change of indoor temperature due to the radiation from the blinds' slat and convective activities in between the blinds and windows. This also has to be considered.

Analysis was carried out on the floor impact sound level between existing plan and enlarged plan with balcony remodeled. Because there is no standardized method to measure the floor impact sound for the apartment with balcony remodeled, two sets of sound source and receiver position were applied depending on whether it is enlarged or not. As a result, it is discovered that different positioning of sound source or receiver in the apartment with balcony remodeled could lead to different result.

As with the disappearance of a living room window due to the trend in apartment housing construction that prefers a larger, expanded living room, the sound insulation performance of the balcony window is becoming an important factor to determine the level of indoor noise at an apartment unit. Considering that the indoor noise inside an apartment unit is mandated by law at or below 45dB(A), the balcony window is increasingly assuming an even more important role. Sound insulation performance of the window was measured by examining differences in data involving varying angles of incidence of the sound source as obtained from the same balcony window. Also, acoustic intensity measuring was performed at and around the window to determine its sound insulation quality. Results of measuring on the sound source's angles of incidence indicated that the performance showed some differences in lower frequency ranges, though with no significance. Intensity measuring results showed that the sound insulation performance was reduced near the connection part of the window and the window frame.

At the beginning the 21st century, we are interested in renewable energy especially photovoltaic. So, we have been installed PV at the building roofs so that we call it building integrated photovoltaic. But strictly speaking, installing the PV on the roof is not building integrated. There are few BIPV designs especially for balcony. In the apartment building, roof is good installing place for PV, but its area was limited. Now a day, built apartment building's heights are more and more increased so that the performance of installed PV on the roof cannot be enough to use even the public use. Thereby, we need the new space in the building to install the PV except the building roof. This study suggests the building facade balcony as a new space to install the PV with building integrated PV design. Hence, in this study, we are designed the movable BIPV shading device for apartment building balcony, and verified its performance with computer simulation. Developed device in this study can works as an electronic generation device and an overhang on the side balcony. As a result, the electronic generation performance of device contributes 15~30% to each apartment unit. The more unit width increase, the better contributed device generates.
