This study attempts to explore the organization of domestic space in Belgium and then to compare them with those found in Korea. Data were collected by questionnaires mailed to 110 staff members, both academic an dadministrative, working at Vrije Universiteit Brussel in Belgium.The major findings of the study can be summarized as fllows: First, the most common pattern of Belgian LDK(living-room dining-room and kichen) layout is the LD type, which separates K from L and D by wall or door while linking L and D to each other. On the other hand, a large portions of Korean LDK layout is the DK type , which seperates L from D and H, but D and K are interconnected. As expected, the bigger the size of floor space, the more likely L-D-K type is to be, which places L, D, and f, separate each other. And the smaller the sire the more probable the DK type and/or the one room type would be, where L, D and K are merged into one room. Second, the enterance of domestic space in Belgium is normally found adjacent to public space. The Belgian entrance often forms a space independent from other parts of the house, or a space that leads directly to garage. These two patterns are rarely found in Korea. Third, Belgians tend to locate Kichen in the front of the house when they design apartment units, Whereas it is not the case in Korea where it is located in the rear.

Recently, as the problem of the traditional on-site labor-intensive construction production method has been raised due to changes in construction work labor and site conditions, the OSC method is gradually spreading as an alternative to this. Even in apartment houses, the application of the PC method is expanding centered on the underground parking lot, but the high cost structure is a problem compared to the conventional formwork method. In this study, factors affecting the calculation of construction cost in the economic evaluation, which are the core of determining the construction method for apartment buildings, are derived through domestic and foreign literature review and expert advice, the importance was analyzed through an opinion survey targeting industry experts. The measures to reduce construction cost were mainly derived from the improvement of the design and manufacturing process. It is expected that the factors affecting the construction cost and improvement measures of the PC method derived from this study will serve as a direction for technology development to spread the application of the PC method for apartment houses in the future.

Recent rise in the supply rate of new public apartment houses leads to an increasement in disputes regarding the construction quality of the apartments between the residents and the construction companies. According to the dispute cases filed for claiming the collective defect repair fees, inter-layer concrete joints turned out to be the most frequently disputed item. For this reason, this study selects the inter-layer concrete joints to further analyze the primary causes and details of each dispute case. From the results of this study, three primary causes of the disputes are found, which are 1) the absence of standard specifications for construction quality control and management after construction; 2) the absence of established standards for repair when construction defects are found; and 3) the fact that the court grants generous compensation for disputes concerning the apartment houses. In order to prevent construction defects in inter-layer concrete joints, this study provides three suggestions including 1) the current standard specifications for inter-layer concrete joints should be further specified by the Ministry of Land, Infrastructure and Transport; 2) a construction defect should be judged according to the compliance to the standard specifications; and 3) a clear and institutional protocol needs to be established for defect repair in cases that new public apartment houses have been judged to have defects.

Windows have an great effect on annual building load because windows are the weakest parts of building envelope thermally. To reduce the consumption of building energy, the thermal performance of window has to be improved in first place. Therefore this research aims to make a quantitative analysis of the heating and cooling load according to the window thermal performance using the heat load simulation program. As a result of the simulation, annual heat load is down 38% according to the decrease of U-value of window, 1.00 W/$m^2K$. and annual heat load is up 10% according to the decrease of shading coefficient, 0.20. The annual load of the window with Low-E glass is 15% lower than the window with pair glass.

In this paper, we design a ubiquitous home automation system for Korean domestic 33-Pyung Apartment based on USN environment. The core of this home automation system is to give Home the 'Intelligence' so that the house can analyze and memorize the occurrences and react spontaneously on the user requirements by means of the World Model, USN, and LBS etc. Ultimately, the resident of this intelligent home might access all of these ubiquitous environments without any feelings about the equipments and peripherals. The methods of user identification, image recognition, and the ultrasonic sensors locations have been applied to Korean domestic 35-Pyung Apartment, but they will be easily generalized to be an extended model because of the flexibility of the World Model. which are confirmed by the imaginary scenario presented at the end of the main left.

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.
