The purpose of this study is to examine residents' perception and needs for storage according to the family life cycle. In order to achieve our goal, the questionnaire survey is used. We sample the questionnaire surveys of 250 apartment households in Seoul. The data collect by the questionnaire survey was analyzed by examining the frequency, percentage on the SPSS/PC+ Statistics package. The results of the study are obtained as follows: 1) In research on the actual storage condition, residents tend to feel constraint on storage of the season goods and the storage satisfaction on the service area is founded lowest. Therefore, it is needed more efficient space plan on the balcony storage and the interior storage for the season goods. 2) In research on the storage consciousness and attitude, residents tend to keep the goods of no use and prefer to arrange neatly rather than use conveniently. Therefore, it is needed more efficient space in the balcony for the storage of the goods of no use and the colsed furniture rather than the open furniture is suited for arrangement. 3) In research on the storage needs, needs for the built-in furniture in all family life cycle show highly and residents want to a space for the exclusive use of the storage. In a solution, we propose to equip with the interior storage and the exterior cooperative storage

The apartment will be much more convenient than the other one in the application of green technologies, providing the merits by mass production. For example, pre-manufactured building materials can be effectively adapted to the formation of buildings. Recently, the form of double-enveloped window system has been developed for the purposed of minimizing energy loss occurred around windows. On the other hand, the expansion of balcony area was legalized and thus, a visual buffer area does not exist any more. All-glass window wall on apartment houses without a balcony produces pretty harmful area with direct sunbeam. A various types of glass can be applied to the window system and it plays a critical role in the determination of inner visual environment. For the purpose of verifying the potential of its daylighting, a mock-up model has been constructed and tested. The refurbished version of conventional window shows its illuminated characteristics. Clear and Low-e glass have been adapted for window area and daylighting ratio has been compared in both test cells.

Purpose: Various policies to reduce the energy consumption have been carried out to save Earth environment against global warming and environmental pollution in many countries. Energy consumption of buildings in Korea has reached 24% of total energy consumption, and energy consumption of apartment has been continuously increasing. Therefore, Korea government has executed building energy efficiency rating certification system to control energy consumption of buildings. Method: This study was conducted to evaluate the energy performance of apartment unit plans according to the increasement of front width of unit plans, and tried to present the basic data to design more energy conscious unit plans for apartments. For the study, three shapes of unit plans -the 2Bay, 3Bay and 4bay unit- were selected for imput models. They were simulated using ECO2 software to assess building energy efficiency rating certification in Korea. Result: According to the results, in cases that balcony windows were not installed, the primary energy consumption of the 3Bay and 4Bay units were less than 2Bay unit, respectively, 0.1% and 2,5%. The primary energy consumption of the 3Bay and 4Bay units, in cases that balcony windows were installed, was less than 2Bay unit, respectively, 1.7% and 3.2%.

The purpose of this study is to analyze characteristics of apartment housing unit plans based on analyzing overall patterns of housing unit plans and identifying the types of unit plans according to the size and to provide the fundamental data for developing diverse dwelling unit plans of apartment. This study deals with apartment housing unit plans built between 1999 and 2000 in Seoul, the capital region and new town. The major findings of this study are as follows; 1) Most apartment housing unit plans have fixed and uniform layouts. Most apartment housing units have L-DK type meaning they have isolated living room space. Certain layouts(especially $60-85\textrm{m}^2$ sized unit plans) show a "trickle-down" phenomenon with respect to the areas of units according to time series. 2) New plan types are rarely proposed since 2000, especially in large-sized(area more than $120\textrm{m}^2$) and $60-85\textrm{m}^2$ sized plans. 3) Another feature of apartment housing unit plans is increase of the service are (balcony, entrance area, additional kitchen, and storage area), and introduction of masters space (composition of master bedroom, dressing room, powder room, path, and etc.) and etc.)

This study aims at finding the trend changes of spatial configuration in housing units of Korean apartments in the 2000s. Among the housing units in the apartments built by large construction companies, we have selected ones with small and regular sizes, $59m^2$ and $84m^2$ respectively, and investigated the number of bays, the location of wet zone and the spatial flexibility in the housing units selected for analysis. In conclusion, the number of bays in the housing unit has gradually increased, after allowing for the structural change of the balcony in the legal. It is estimated that the trend has came from the intent to increase the numbers of the externally exposed surfaces of the balcony, ensure a good view, lighting, ventilation and spatial flexibility. The location of wet zone, water-needed space such as a bathroom or a kitchen, has changed in the direction to facilitate the expansion and modification of space. Variable range of space has gradually expanded by using the balcony and wet zone as much as possible. In order to configure more effectively spaces in housing environments, the future study should be implemented to develop tools for realizing sustainable housing environment at the levels of not only the housing unit. but also the entire building, housing site, and city.

Regarding to the Domestic housing politics to improve residing environment and effective use of country land, apartment buildings have been constructed since early of 1970s. Now apartment is taking over 50% out of entire housing in Korea. In the view point of PV application to the apartment, PV has amny advantages because of the wideness of out-walls and high floors building in APT. Therefore, if APT could use the electricity produced by BIPV, we can solve more easily environment and energy problems caused by housing. The research conclusion by analysing conditions and application method to introduce BIPV application to APT in near future is as below. -The out look of APT has been developed periodically and recently gable roof or canopy is popular which PV installation is more favorable. -For Balcony part with double skin facade sassy window, It has a preferable condition to install on the wall depending on the window direction. -In case of shorter distance between buildings due to high ratio of outside measurement, it is more desirable to install PV on the roof than on the wall of Apartment by considering low solar altitude. -Also depending on the direction of APT building, it is more effective and productive in electricity in the broad surface of side wall of APT. -In case of superhigh floor APT where facade system is mostly double skin facade of curtain wall system, PV module can replace the traditional curtain wall and will reduce architectural materials and obtain various out look design thereof.
